How to calculate max lot that we can trade.

New comment
 

Hi all,

When I trade with my $ 8,900 demo account and open buy with 7.5 lots the error massage is "not enough money".

Can anybody help me, how to calculate max lot that we can trade ?.

thanks

 

Depends firstly on the MAX_LOT size the broker has set...

Also on leverage, other open trades on the account, base currency of the account relative to the base of the pair traded, etc

As as example

200:1 leverage

Euro based account

An order of EURUSD

7.5 lots would require a free margin of at least €3750 + spread

(so 400:1 leverage would need around €7500)

Note - some brokers have a 'minimum free margin level' above zero, others (effectively) below zero

Good Luck

And do you know how to check the leverage with MQL4 ?

Use AccountLeverage() function.

 

Thanks robofx.org,

one more question, how to increase lots in pending order ?, eg: from 3 lots to 5 lots.

I usualy close order and open new one.

Is there any easy way ?

thanks

Use the OrderModify() function.
