Hi All,
I would like to ask someone to clarify me 3 basic things:
when MT4 executes a command: OrderSend() - is it waiting to get a confirmation from the market that the order has been confirmed / refused / requoted / etc., or it's going immedialtely to next command ?
how exactly should I deal with requotes in my EA ?
in manual trading when requote occures I (teoretically) have a moment to confirm requoting of the price.
in EA system sends me an error #138 and than what am I supposed to do ? is there any way to confirm the requoting procedure or should I send the same command with the same parameters again ?
it's seldom, but occures from time to time to get a busy context... but actually what does it mean ?
is there any way to check the context business prior to sending an ordersend() command ?
will marketinfo(symbol(), MODE_TRADEALLOWED) solve the problem with context ?
thank you in advance for prompt and professional answer,
CoVal
