Hi there,

We have received the exception and the issue will be solved in an upcoming release.

Regarding the SL issue, we would need the cBot code and backtesting parameters in order to reproduce this and explain what happens.

Best regards,

Hi Panagiotis,

In visual backtesting another instance, I received another crash with error code #6271DD1D. 

Can you also solve this error in upcoming release please?

Can you also tell me the broker? This usually happens when your SL falls within the symbol's spread. Please check if this is the case

Hi there,

You can use Positions.Opened event and check if the stop loss was set. If the stop loss is null you can act accordingly i.e. place it at a valid distance.

I want not to submit an order if the StopLoss price is invalid. 

so, I wrote a if check statement like below but my order is still without SL (empty SL). Why?

double stopLossPrice = Symbol.Bid - StopLossPips * Symbol.PipSize;
double takeProfitPrice = Symbol.Bid + TakeProfitPips * Symbol.PipSize;

if (stopLossPrice < Symbol.Ask - Symbol.Spread) // Check if stop loss is valid
     ExecuteMarketOrder(TradeType.Buy, Symbol.Name, volume, "Test", StopLossPips, TakeProfitPips, stopLossPrice.ToString());
