RightEdge - The Ultimate Backtesting and Trading System Development Platform
Live Data Pane
The live data pane is where incoming tick data can be viewed. Starting the data stream happens one of two ways. The first way is to start live data manually using the Start button on the live options toolbar. The second way is to start a live system. After the live system is loaded and the specified amount of historical data is loaded, the live system will automatically begin live data collection.
Once live data is started it can be stopped by the stop button on the live options toolbar or by stopping a currently running system.
Discarding Live Data
Depending on the number of symbols for which you are capturing live data, whether you are saving tick data, and other factors (such as the speed of your computer), live data may arrive too fast to process. As this happens, the list of pending ticks will grow. Eventually, RightEdge will catch up by discarding all of the current pending ticks. A warning will show up at the bottom of the live data pane as shown below.
You can control the length of time before RightEdge discards tick data with the Maximum Live Data Backlog setting. To avoid discarding data, you can reduce the number of symbols you retrieve data for, switch to a higher performance data store, or turn off the option to save raw tick data in the watchlist folder settings.
Tick data may also be dropped if the time for a tick is out of order, or if it is outside of exchange hours that you have specified in the live options.
Configuring the View
Different pieces of tick data are valuable to different systems and different asset classes. For example, the bid and ask portions of the tick are more valuable than the last price in the case of forex. To accommodate varying needs, the columns displayed as well as the column order are configurable and persist between program runs.
To change the order of the columns, simply click and drag a column. Release the mouse button when the column is dragged past the boundary of the target column. Using the above illustration as an example, to put the Last Volume column at the far right, click and drag the Last Volume column until it is past the rightmost border of the Change column.
Columns in the grid can also be added or removed. This is accomplished by right clicking anywhere in the grid and selecting the Configure Columns menu option.
The list on the left contains the columns that are not displayed currently but may be displayed if desired. The list of the right contains the columns that are currently displayed.
Click the Add >> button to move a column from the Available Columns list to the Visible Columns list. Click the Add All >> button to move all of the available columns into the visible columns list. Click the << Remove button to move a column from the Visible Columns list back to the Available Columns list. Click the << Remove All button to move all of the visible columns into the available columns list.
Once the desired columns are in the Visible Columns section, clicking a visible column entry will allow individual column manipulation. When a visible column is selected it can be ordered using the Move Up and Move Down buttons.
Column Size will change the size of the currently selected column.
When applicable, the Decimal Places field will be enabled to allow setting a default number of decimal places when the value for this column is rendered.
