Max Lot Size that i can execute based on AccountBalance (MQL4)

Hello friends!,
How can i know / How can i build a function in MQL4 that will tell me what is the Maximum Lot Size that i can trade with based on my AccountBalance in MQL4?

i'm trying to backtest something but im getting the ERROR: "Error opening order: 134 : not enough money.",

That error happens when the EA trying to execute a trade with a much higher Lot Size that it should use,

the question is how can i avoid this error and still execute the trade but based on the maximum lot size that i can execute based on my account balance?..

that way it will still execute an order but with the maximum lot size it can pull, so i wont get this error and wont miss trades.

BTW the function must calculate the Leverage and Margin..

thank you i how you understand

It depends on the broker. Go to market watch and right click your instrument, say EURUSD then go to specification. There you can see maximal volume. Usually it will be 100 lots, some 1000 lots.

thanks but i need the mql4 code function that tells me what is the max lot i can open with my account balance with my margin, i know that my max lot size is 100 or 1000 with some brokers...,

please help..

NVM, FIXED , thanks

Hi Karish, I'm having the same issue. Can you share what you found to fix the problem?

Probably the attached spreadsheet might help.
