How to check opened order is long or short?

[John Voidman]

Hi, fellow MT4 users. I have a simple logic in trading which in pseudo would be 

if(no order in the order pool)
  can long or short otherwise wait ;
if(exists opened long order) 
{
  if(situation A meets)
    close order;
}
if(exists opened short order)
{ 
  if(situation B meets)
    close order; 
}

This first if would be easy as if(OrdersTotal()==0) which means no pending or opened orders in the order pool, which is what I need.

But the second if and third are tricky cause I'd like to check "opened" orders are long or short not just orders(which include pending orders). How should I do this?

use Orderselect

Pak Hong Poon:
use Orderselect

OrderSelect(index or ticket, flag, mode)

MODE_TRADES (default)- order selected from trading pool(opened and pending orders)

To my recollection Orderselect can't exclude pending orders.

Use OrderType()

It's either OP_BUY or OP_SELL

See here https://docs.mql4.com/trading/ordertype

And make sure to select the order first by using OrderSelect() function.

you can choose after you selected the order, that is what "select" means

I think this way still could select pending orders and check it's type what I need is just opened orders not pending ones.

You can simply reject any order other then OP_BUY and OP_SELL in your code.

Then it will just skip any pending orders.

They carry a different identifier.

OP_BUY - buy order,
OP_SELL - sell order,
OP_BUYLIMIT - buy limit pending order,
OP_BUYSTOP - buy stop pending order,
OP_SELLLIMIT - sell limit pending order,
OP_SELLSTOP - sell stop pending order.

Thanks, that's new knowledge for me, much obliged.
