Thank you! That's really helpful!As I closed MT5 the log reseted,
here are screenshots of everything I've found on the MT5 folder that looks like a log file.
3 first pics are the log file in MT5, last one is the log file in MQL5-Position sizer
I hope it's enough. Thanks for your time.
PS I'm on ver 3.07
First, about not being able to cancel the order. This has nothing to do with the Position Sizer and should be resolved with your broker's support service. There is simply no way an attached EA can influence your ability to manually close orders.
Now to the Position Sizer opening a Sell Stop order. You say that you had a Pending order set up, but the PS unexpectedly opened a Sell Stop order. A Sell Stop order is a type of a Pending order. Were you trying to open a Sell Limit order or a Buy Stop order instead?
