Use MarketInfo, as suggested.

But if you are using OnTick() to activate code on a new bar, remember that a new bar on your host chart doesn't mean a new bar has started on any other symbol. So you'll need a way to identify a new bar for each symbol. I ended up using a struct array to keep a track of each symbol and it's current bar time, might be a better way!

The open, sell, close functions you'll find are straightforward once you get your head around MarketInfo.

Hi Andrew,

Thank you for your help and reply, I saw many useful Info in MarketInfo() and I am trying to use it. It seems this will help me. I am developing a small subroutine and pass the trade parameters like Symbol, SL, TP, Lot size, and more to it. it will open order and return false if fail or true if it is successful. I hope I can do this task. Thank you again for help
