(MQL4) How to send multiple orders at the sametime?

[Chan Mike]

I am using two OrderSend to send out two market orders. If the market is moving quickly, the price of two orders could differ(previous tick to current tick). How can i send two market orders simultaneously that makes the entry price of two orders the same?

You can't send two market orders at the same time.

You can have two orders at the same price only with pending orders - send two stop or limit orders with the same price, again one at a time.

You can't. Send out one order with double the size and do a partial close where the first TP would be.
