OrderSend in backtest mode

[[Deleted]]

Can OrderSend return -1 in the backtester?
I have an EA which gets different results in the backtester depending on if I handle OrderSend errors.

See documentation https://docs.mql4.com/trading/OrderSend

The main function used to open a position or place a pending order. Returns number of the ticket assigned to the order by the trade server or -1 if it fails. To get additional error information, one has to call the GetLastError() function.
