IB Symbol

Fritz — Tue, 15 Jul 2008 06:59:16 GMT

I have installed RE 2008/1 366 and try to configure my watchlist with IB-Futures. All woks fine with ES,ER2,NQ,EMD,ZN and ZB but I cannot get historical data for YM, 6A,6B,6C,6E, QM,QG

I also have tried AUD instead of 6A but I always get the error no 200, IB-Symbol not correct.

How can I setup my watchlist for ib-futures ?

Live system misses trade signals

Ossie68 — Wed, 02 Jul 2008 06:54:34 GMT

My live system seems to ocassionally ignore trade signals based on 1 minute data. In those instances, it does not generate pending orders (it goes without saying that the live system was activated). However, when I run a simulation these trades do show up in the trade list results as expected. What could have caused this?

How to place a simple trailing stop?

ThomasZ — Sat, 07 Jun 2008 20:01:04 GMT

Hello,

can someone please show me an example that shows how to place a simple trailing stop that takes the lowest low of the last 3 bars on a long position. Or if the way to implement it is principle the same then just a simple ATR TrailingStop.

I've searched for it but wasn't really successfully. Even also the examples that are delivered with the RE installation doesn't include a trailingstop. However, we all know how important a trailing stop is. :)

Live system does not initiate orders

Ossie68 — Wed, 21 May 2008 15:19:53 GMT

I try to run my trading system in the live environment but it does not place orders upon trigger signals. I have my IB TWS simulation (paper trading) account running in the background to execute the orders but nothing happens. However, the IB live data feeds works fine and so does the trading system when running the simulation. Also, the folder that contains the symbol I want to trade has IB set as the Broker Service to be used. What am I missing here?

The symbol I want to trade is an 'EOE' future (Currency: EUR / Exchange: FTA / Tick size: 0.05 / Contract size: 200 / Exchange opening hours from 9 AM - 17:35 PM CET or 3 - 11:35 AM EST). I understand from http://www.rightedgesystems.com/forums/FindPost1819.aspx that you have to make sure that you have the tick size and contract size set correctly in the symbol information, otherwise IB may reject the order because it does not conform to the minimum price variation.

Error after starting live system

Ossie68 — Tue, 27 May 2008 04:31:05 GMT

RE succesfully executed an order on a trading system signal that appeared in the Open Positions pane as well in my TWS paper trade account. Later, I stopped the live system and when I tried to restart the live system some time later, I got the below error message. I don't see the open position in RE any longer but I do see it in TWS, however, I notice that the "API" page tab in TWS that was created once the order was filled has disappeared.

EOD Market Order; what price is used?

hairy_mug — Mon, 26 May 2008 10:11:15 GMT

I build a system and test against the "paper broker".

When it fills a market order, what price does it use? For EOD is market the H+L*.5 (average price)?

and does it base the fill on today's price OR the next day's price?

Clearly, when the system goes live, the entry orders I place (based on the scan) will be delayed by a day; the exit market orders will also be delayed...

Just trying to get ny head around it...

Thanks!

Stop loss order rejected

jcd77ehq — Tue, 20 May 2008 15:33:08 GMT

I'm using Live System to trade through Interactive Brokers and I'm having a bit of a problem with the stop-loss orders. The market order to buy gets filled and the stop-limit order for my profit target goes through but the stop-loss order always comes back "Stop loss order rejected: the price does not conform to the minimum price variation for this contract."

I've searched the forum but I don't seem to see this problem mentioned. Any help is appreciated. Thanks.

Discretionary trades

phg — Tue, 04 Mar 2008 09:28:22 GMT

While discretionary trading is a welcome addition, more explanation is needed. Are fill, cancel and update events triggered? Do the trades happen immediately, or at the next bar end (as if they constituted a "trigger")? One concern is that my placeorder procedure sets a number of enviromental conditions that are presumed to be in place when events occur. Is there a flag that distinguishes discretionary trades from others? That might be used to exempt discretionary trades from some checking.

Further, one might want the ability to declare that a trade has occured, one that does not drive events. This arises where you have made a manual trade in TWS and you subsequently want your RE strategy to pick the point to cover.

(I don't find anything in the Help or Guide documentation?)

PositionOrder Examples

phg — Wed, 17 Oct 2007 16:51:32 GMT

Are there any examples of the use of PositionOrder objects in any of the sample strategies or ones uploaded to the site? Am I right that you have to use one if you want to set a BarsValid number?

Something is wrong but what?

Running in live strategy mode after the system executing an openingsorder on signals this error is made.In the live system console the order is set as pending order.

Broker = paperbroker connected through TWS from IB.

Realtime Hedge: OpenPosition() called form OrderFilled()

DrKoch — Mon, 14 Jan 2008 10:06:12 GMT

In order to get a realtime hedge I tried to open a short position whenever one of my long positions gets filled.

I placed an OpenPosition( ... Short ...) inside the OrderFilled() Event Handler.

BUT: it looks like RE ignores this OpenPosition() call. If I place exactly the same call somewhere outside the event handler (say in NewSymbolBar) everything works fine...

Any ideas?

Position order status

phg — Thu, 18 Oct 2007 07:25:48 GMT

Suppose a bought position rises over time such that you would like to establish a trailing stop to sell, but not if there is already some form of a sell-type order pending (from a previously handled trigger). Or vice-versa. I'm trying to figure out how to establish either a SetProfitTarget or a trailing stop, but not if the other is already in force.

Is there status information about outstanding order(s) against a position, given the posID? Perhaps this situation is such that good use could be made of the 'tag' property, to keep track of what order is outstanding? Can more than one order at a time be outstanding, or does submitting an order cause an outstanding order to be canceled?

IB forex symbol names

jthorne — Mon, 13 Aug 2007 23:30:17 GMT

Okay, this should be easy, but I've failed on every count. What is the proper symbol naming convention for forex pairs when connecting to Interactive Brokers?

GBPCHF
GBP.CHF
GBP/CHF

Everything comes up unknown. I know the data connection to IB is good (I can easily retrieve stocks).

Stop Orders in Paper Broker

BigBerner — Mon, 30 Apr 2007 22:37:03 GMT

Stop orders in the Paper Broker do not seem to work correctly. It seems to me that it will take the last traded price of the last bar as the stop level irrespective of what you place in "limit" in SystemData.OpenPosition.

Also orders that get filled in the Paper Broker are not updated in the Live System window until the start of the next bar.

And lastly, how do you place a StopLimit order? There does not seem to be any place to pass a stop level and a limit level.

Sell at limit order

Jones — Sun, 03 Jun 2007 08:39:34 GMT

Hi,

This seems a dumb question to ask, but I havent been able to find a reference in documentation or an example strategy that does it.

How do I do a sell at limit in c#?

I can see OpenPosition() can have an order type of limit, but ClosePosition() is at market only.

Live System does not place order

kd7038 — Fri, 23 Mar 2007 17:02:42 GMT

I tried to run the following trading system in the live system:

using System;
using System.Drawing;
using RightEdge.Common;
using System.Collections.Generic;
using RightEdge.Indicators;

public class SystemMain : SystemBase
{
public override void Startup()
{
// Set system wide options here

// Here is your profit target value
this.SystemData.ProfitTarget = 0.04;
// Here is your time out exit value.
// Change this to 0 for no time-out
this.SystemData.BarCountExit = 7;

// Set up indicators here
Indicators["BBL"].CreateIndicator(new BollingerBandLower(14, 1.9));
Indicators["BBL"].SetInputs(BarElement.Close);
Indicators["BBL"].SeriesColor = Color.Red;
Indicators["BBL"].AddToCharts();
}

public override void NewSymbolBar(Symbol symbol, BarData bar)
{
ISeries bbLower = Indicators["BBL"][symbol];
double targetPrice = bbLower[bbLower.Count - 1];
string id = string.Empty;
string des = string.Empty;
//this.SystemData.OpenPosition(symbol, PositionType.Long, OrderType.Limit ,out id targetPrice);
this.PositionManager.OpenPosition(symbol, PositionType.Long, OrderType.Limit, targetPrice, 0, des, id );
}
}

I use IB Paper Trader. Live System Bars = 20

It works fine in simulation mode.

Thanks

Duplicate fills reported in Paper Broker

BigBerner — Tue, 01 May 2007 02:13:48 GMT

If you set PositionManager.SetProfitTarget and PositionManager.SetStopLoss at the same time in the Paper Broker and then one of the orders is hit, you get a duplicate notification in the Closed Positions tab. Here is example code.

Public Overrides Sub OnPositionTrade(ByVal trade As RightEdge.Common.Trade, ByVal pos As RightEdge.Common.Position, ByVal state As RightEdge.Common.Position.State)

MyBase.OnPositionTrade(trade, pos, state)

Dim OnePoint As Double = pos.Symbol.SymbolInformation.TickSize

Dim LongProfitTarget As Double = trade.Price + (3 * OnePoint)

Dim LongStopLevel As Double = trade.Price - (3 * OnePoint)

'Set Profit Target

If pos.PositionType = PositionType.Long And state = Position.State.Open Then

PositionManager.SetProfitTarget(pos.PosID, LongProfitTarget, False)

End If

'Set Stop Loss

If pos.PositionType = PositionType.Long And state = Position.State.Open Then

PositionManager.SetStopLoss(pos.PosID, LongStopLevel, False)

End If

End Sub

Broker Service

BigBerner — Mon, 19 Feb 2007 03:01:35 GMT

I have started building a Broker Service and have a few questions.

1. Could you explain to me what the purpose of AddOrderUpdatedDelegate, AddPositionAvailableDelegate, RemoveOrderUpdatedDelegate, RemovePositionAvailableDelegate is. I couldn't really work out what I was supposed to be doing here from the sample.

2. My Broker does not have a function to return the cash in the account for GetBuyingPower. Should I just set this to 0, or will that stop orders going through? (in which case I guess I would set it to 10,000,000 or something like that)

3. My broker API only allows for limit and market orders to be placed. Am I correct in saying that this means that when I write a strategy in RE, that whilst I can use stop orders for back testing, that when I switch to live trading I will need to change my code to handle the stop from within RE. I am assuming that when a stop order is generated by a strategy in RE that it is sent directly to the broker for monitoring within the broker software, rather than being moinitored by RE and released as a market order when the level is hit. (What I am getting at here is, is the functionality of the BrokerOrderType enumeration members handled by RE, or does your broker software need to be able to handle this functionality?)

4. Really just a comment here, but I thought the BrokerTransactionType enumeration members names to be a bit confusing (Buy = Buy, Short = Sell, Sell = Close long, Cover = close short). Would have made more sense to have something like, Buy, Sell, ExitLong, ExitShort.

PositionManager.SetStopLoss

BigBerner — Thu, 03 May 2007 02:55:48 GMT

If you use PositionManager.SetStopLoss in the Paper Broker it generates an order of type StopLimit. I think this should be an order of type Stop.

Cancel Orders

BigBerner — Thu, 26 Apr 2007 22:51:23 GMT

I am having trouble with cancelling an order. The bit I am having trouble with is tracking the order ID. Lets say I am running a system on a number of symbols, I place an order to buy on stop, and the next bar I wish to cancel the order. How do I get the orderID for that order? If I call PositionManager.GetPendingOrdersForPosition(PosID) I need the PosID, so I tried setting a PosID in SystemData.OpenPosition and using that, but when I run a simulation I get the error message that the PosID has already been used. If I let RE assign a PosID in SystemData.OpenPosition how would I know what PosID goes with the order I am trying to cancel. I am sure there is a simple solution but I am not seeing it at the moment.

Live System Window

BigBerner — Wed, 11 Apr 2007 02:34:24 GMT

When an order is input to the Live System window the Limit Price column is formatted as $xx.xx. The format needs to be changed as not all prices are in dollars and cents. Also if a price has more than two decimal places it is being rounded to two at the moment.

Thanks.

Orders and order management

BigBerner — Thu, 22 Mar 2007 00:06:37 GMT

I think a tutorial on order placement and management would be useful. It has taken me quite a while to work out how to do things. Most of the systems uploaded on the site simply place buy orders at market and nothing else. Also I am finding some of the terminology used a little unclear.

For example if I place an order to buy on stop just above the market using systemdata.openposition I will now have a working order in the broker. I only want to have this order placed once. Does the "Max open" field in the Position Management section of the system properties stop this order from being placed again when the next bar completes (assuming I set it to 1) ? There are currently no open positions but if it lets it go through there are going to be more than one.

How do I check what orders are currently being worked in the broker? I think it might be PositionManager.GetPendingOrdersForPosition or .GetPendingPositions. What is the difference between these two functions?

Modify Order method

BigBerner — Thu, 22 Mar 2007 06:32:02 GMT

Any thoughts on having the ability to modify a working order. As things stand at the moment I think you need to cancel the order and then place a new one. There are a couple of drawbacks doing it this way. Firstly if the order has been partially filled then there is some extra work involved in getting the unfilled quantity in order to place the new order. Secondly, if you are trading a deep market you may be sitting in a queue waiting to get done, and by cancelling the order and placing a new one (say if you wanted to alter the quantity of the order) you lose your spot in the queue and go to the back of the line. I don't think it is anything that is urgent, but it would probably warrent doing sometime in the future.

Symbol Open Time/ Close Time

BigBerner — Wed, 28 Feb 2007 18:47:35 GMT

I am building a broker plugin for a broker that only supports limit and market orders through its API, so I am handling other order types myself in the plugin. To handle market on close or market on open orders I need to get the open and close times for a symbol. Any suggestions on how I could do this?

Supported Broker plans

BigBerner — Wed, 28 Feb 2007 19:01:34 GMT

Just out of interest I was wondering what brokers you plan to support in the future. In terms of wide appeal probably PATS and Trading Technologies would be my suggestions. I use EccoPro (www.eccoware.com) and have built to their API but it would be nice to know there are some alternatives available. Also if you do plan to add any brokers, any ideas on when you plan to do this?

OrderType and BrokerOrderType

BigBerner — Thu, 22 Feb 2007 02:38:43 GMT

Just noticed that the OrderType enumeration and the BrokerOrderType enumeration have different members. OrderType has Market, MarketOnOpen, MarketOnClose, Limit and LimitOnClose, whereas BrokerOrderType also has PeggedToMarket, Stop, StopLimit, and TrailingStop.

Currently using the OpenPositionMethod I would not be able to place PeggedToMarket, Stop, StopLimit and TrailingStop orders. It looks as though the OrderType enumeration has not been updated to include these order types - is this correct?

New methods added to IService Interface

dplaisted — Mon, 26 Feb 2007 21:41:22 GMT

We have added three new methods to the IService interface. These methods allow a service to define various custom settings, and to display a dialog to modify them. They were added in response to feedback that services may need more settings than a server address, port, username, and password. They were also added to allow commission settings to be specified for the paper trade broker.

Here are the three methods:

[code]

bool HasCustomSettings();
bool ShowCustomSettingsForm(ref SerializableDictionary<string, string> settings);
bool Initialize(SerializableDictionary<string, string> settings);

[/code]

If you have written a service plugin, you will need to add these three methods. If you do not need to use custom settings in your service, return false from HasCustomSettings() and ShowCustomSettingsForm(), and return true from Initialize().

If you would like to use custom settings, then return true from HasCustomSettings(). This will enable the "Other Settings..." button in the service setup dialog for your plugin. When this button is pressed, ShowCustomSettingsForm() will be called. You should then show a dialog allowing the settings to be changed. If the user accepts the changes made in your dialog box, you should return true, and the settings dictionary that was passed in should reflect the updated settings. If the user cancels, return false. The Initialize() method will be called just after your plugin is created, giving you access to the current custom settings.

The settings dictionary that is passed to you will be empty the if the service has been created and the user hasn't set up the custom settings yet. Also, if you want to store some type of data besides a string, you will have to convert it back and forth. Here is some sample code from the Paper trader which shows how you can handle these issues.

[code]

private double _flatCommission = 0.0;

private double _perShareCommission = 0.0;

private double _minCommission = 0.0;

private double _maxCommission = 0.0;

public virtual bool HasCustomSettings()

{

return true;

}

public virtual bool ShowCustomSettingsForm(ref SerializableDictionary<string, string> settings)

{

PaperTraderSettings dlg = new PaperTraderSettings();
string val;
if (settings.TryGetValue("FlatCommission", out val))
{
dlg.FlatCommission = double.Parse(val);
}
if (settings.TryGetValue("PerShareCommission", out val))
{
dlg.PerShareCommission = double.Parse(val);
}
if (settings.TryGetValue("MinCommission", out val))
{
dlg.MinCommission = double.Parse(val);
}
if (settings.TryGetValue("MaxCommission", out val))
{
dlg.MaxCommission = double.Parse(val);
}
if (dlg.ShowDialog() == System.Windows.Forms.DialogResult.OK)
{
settings["FlatCommission"] = dlg.FlatCommission.ToString();
settings["PerShareCommission"] = dlg.PerShareCommission.ToString();
settings["MinCommission"] = dlg.MinCommission.ToString();
settings["MaxCommission"] = dlg.MaxCommission.ToString();
return true;
}
return false;

}

public virtual bool Initialize(SerializableDictionary<string, string> settings)

{

_flatCommission = 0.0;
_perShareCommission = 0.0;
_minCommission = 0.0;
_maxCommission = 0.0;
string val;
if (settings.TryGetValue("FlatCommission", out val))
{
if (!double.TryParse(val, out _flatCommission))
{
lastError = "FlatCommission was not a number.";
return false;
}
}
if (settings.TryGetValue("PerShareCommission", out val))
{
if (!double.TryParse(val, out _perShareCommission))
{
lastError = "PerShareCommission was not a number.";
return false;
}
}
if (settings.TryGetValue("MinCommission", out val))
{
if (!double.TryParse(val, out _minCommission))
{
lastError = "MinCommission was not a number.";
return false;
}
}
if (settings.TryGetValue("MaxCommission", out val))
{
if (!double.TryParse(val, out _maxCommission))
{
lastError = "MaxCommission was not a number.";
return false;
}
}
return true;

}

[/code]

Thanks,
Daniel

Position management error handling

dplaisted — Mon, 15 Jan 2007 21:45:36 GMT

We are in the process of rewriting our position manager to be much more flexible, to support position resizing, pyramiding, and partial fills. We want it to be as robust as possible. So right now I am considering a "worst-case scenario" which will hopefully never happen to you, but if it does we want to handle it in the best way possible. The issue is what to do if the position size goes "negative."

There might be various ways that this could happen, but here is one scenario. You open a position with 100 shares and a profit target. The profit target is implemented as a limit order to sell 100 shares. Some time later, you decide to sell off half of the position. So the order is sent to sell 50 shares. Normally what would happen is that when you receive confirmation that the 50 shares have been sold, the profit target limit order will be canceled and a new one will be sent for 50 shares instead of 100. But it is possible that the limit price would hit between the time that you send the sell order for 50 shares and the time that you receive the message that the shares have been sold and are able to resize the profit target order. Since you sold 150 shares from a position that only had 100 shares, you are now short 50 shares.

At first glance it might seem like this situation is avoidable by resizing the profit target order before sending the order to sell 50 shares. But you might want to sell the 50 shares with a limit order, and in that case you don't know if it will execute until you receive notification that it went through.

So, if something like this happens, what should the position manager do? Right now I am thinking that it should just use a market order to get you back to zero shares. This seems like what you would do anyway if you ended up with an unwanted position, and I'm not sure what else an automated system could do.

We welcome any feedback you may have.

Virtual broker

billb — Tue, 17 Oct 2006 08:44:34 GMT

We've completed the initial development of a virtual broker and integrated it with RE. This puts us in a very good position for implementing real brokers. Since the virtual broker acts like any other broker to RE, the plumbing is in place and we're pretty excited about this development. Will keep you posted.

Is the Broker Interface for Interactive Brokers Available for RightEdge?

steinhausq — Mon, 14 Aug 2006 11:11:48 GMT

I would like to know whether the current beta release of RightEdge includes a functioning broker order interface to Interactive Brokers?

Is it possible to generate orders to IB from RightEdge at this time?

Are there any examples or code snippets on how to generate realtime orders to a broker from a RightEdge trading system?

Thanks!
