WLP stops working after I've using it for a few minutes or longer. Seems to happen while doing optimizations. I would appreciate any help you can give me.

Thanks

We're interested in how can the issue be reproduced, so could you follow this checklist to send us a detailed report?

* Is there any other activity going on? How many workspaces? Other WL tools running?
* Which Optimizer produces the crash (Exhaustive, MC, GA)? Or does it happen with all? Immediately or after some number of runs?
* Portfolio simulation mode? or Raw Profit mode? If latter, maybe a specific symbol?
* Position Sizing and Data Loading settings
* Which data provider? External symbols used?
* Strategy code - custom? bundled strategy? rule-based?
* Preferences (F12) - in case any changes were applied to Backtest, Slippage, and Advanced, indicating them won't hurt

We're interested in how can the issue be reproduced, so could you follow this checklist to send us a detailed report?

* Is there any other activity going on? How many workspaces? Other WL tools running?

Other activities: I frequently have at least a web browser and Active Trader Pro running at the same time.
Workspaces: I have not created any workspaces.
Other WL tools running: I usually have one oe two more optimizations running at the same time for the same symbol.

* Which Optimizer produces the crash (Exhaustive, MC, GA)? Or does it happen with all? Immediately or after some number of runs?

I use GA. Never occurs immediately.

* Portfolio simulation mode? or Raw Profit mode? If latter, maybe a specific symbol?

Raw profit mode. Just happened on .RUT.

* Position Sizing and Data Loading settings

$1,000,000. One year of daily data.

* Which data provider? External symbols used?

Fidelity. I don't know what external symbols are.

* Strategy code - custom? bundled strategy? rule-based?

I'm using strategies I created using rules and then converting to code-based.

* Preferences (F12) - in case any changes were applied to Backtest, Slippage, and Advanced, indicating them won't hurt

Backtest Settings: No boxes checked.
Slippage: No boxes checked.
Advanced Options: Open the Orders window and "Also, switch to view the Orders for that Trade's Account" boxes checked.

Thank you, this is very informative and mentioning GA gives a strong hint. Please click on Support and do "Create a new support ticket" from there for further investigation with the GA developer. tia.
