How to get the maximum number of open positions

[sdlg]

How to get the maximum number of open positions of broker's limit, not the number of Lots. I don't know using which function.

Thanks in advance

I think you can only get the maximum number of open pending orders. I don't think there is a limit on the number of positions.

Margin requirements will be the limiting factor, not the count.

Is that really true?

At least one broker (Roboforex) has a limitation in number of open positions, not only in number of pending orders.

On the Roboforex site you can read:

Maximum number of open positions for MT5 accounts	1000
Maximum number of active orders for MT5 accounts	500

My question is: is there any MQL5 function to get the maximum number of open positions?

Thanka for your answer.

Why have you posted your MT5 question in the MQL4 section, (bottom of the Root page)?

Because I did not notice it!

I'm so sorry.😎
