I have made some progress on identifying the memory leak and expect to have it fixed in the next build.
Thanks,
Daniel

Hi,
I'm currently reviewing RE 2010 using the free trial option of 45 days (great stuff!).
I have coded and tested my first trading system and have the exact same problem: when the simulation is complete and I click the Equity Curve tab, the app freezes and uses 100% of 1 core on my Dual Core CPU.
Can I help you identify the problem? The only thing I did was to click Equity Curve.
Running latest version of RE 2010 on XP Home.
Please let me know if I can be of further assistance.
Best,
PBJ

The system results memory leak should be fixed in the next build.
We still need to fix the equity curve issue, that may or may not make it into the next build.
Thanks,
Daniel

Ok Daniel thanks.
I must bring to your attention that it's hard for a new comer like me to test the software fully before purchasing if I cannot display an equity curve.
Do you have an idea what triggers the freeze (and 100% CPU usage) when the Equity Curve tab is clicked? The graphic component maybe? An infinite loop?
A little more information on my configuration:
OS : XP Home Edition SP3 32 bits FR
RAM : 2.5 GB
CPU : Pentium 4 @3.00 GHz
.Net Framework: currently "repairing" 3.5 SP1 (just to see if the problem comes from it)
RightEdge: Edition 2010 Build 17 - free 45 day trial
System: my first trading system tentative, running simulation on C (Citigroup stock), daily bars from Yahoo! historical data services (included in RE), ~8377 daily bars
Let me know if I can be of further assistance. I'd be pleased to help you help me.
Best,
PBJ

| Too many data points and zooming are two possible causes, but we are also looking into ways to make it faster on our end. Approximately how many bars is your simulation?

One other thing to add to the list to check is when you start a sim and the data starts loading then you cancel the simulation before it finishes.
When doing this have seen it hold the memory that it had been using.

I've improved the equity curve's performance. The chart control was apparently getting bogged down when trying to draw the equity curve with too many data points. I've limited the number of data points to 1000. It still takes up a lot of CPU time when you move your mouse over the chart (because it keeps redrawing it), but I think it will be much improved. This will be in the next build, so once we release that, try it out and let us know.
Thanks,
Daniel
