Calculate the right lot size MQL4/MT4

Hi,

last night i have tried to include the script in attachments in my EA but it doesn't work.

So the main problem for me is the riks per trade. Many people use this function for calculate the right size of lots.

lot=NormalizeDouble(AccountFreeMargin()*MaximumRisk/1000.0,2);

But is not sufficient. So I have found this Script. it is perfect but only for manual traders.

First my GAP Ea with Moving Average and then the Script for the calculation of the Lot size. Can someone help me to include the script in the EA? or give me some suggestions?


Thanks

I don't quite understand how that script of yours is perfect even for manual traders... it doesn't even allow user to declare the amt of risk...

omg

i have found a esier solution for the problem:

lot=NormalizeDouble(AccountBalance()*MaximumRisk/StopLoss/(MarketInfo(Symbol(), MODE_TICKVALUE)),2);


i think it works.

the problem is now that i don't know how to calculate the diff. betwenn Moving Averange and Open of the Pos. I know how but its diffrent for Buy and Sell.

double lot=Lots;
double StopLoss=50;
//---- select lot size
lot=NormalizeDouble(AccountBalance()*MaximumRisk/StopLoss/(MarketInfo(Symbol(), MODE_TICKVALUE)),2);


How can I say it is Buy or Sell Stopp?

double StopLoss = iMA(NULL,0,MovingPeriod,MovingShift,MODE_EMA,PRICE_CLOSE,0)-iOpen(Symbol(), PERIOD_M1, 0);

doesn't work. HELP.

The new trend to go to 5 decimals will hurt your calculations.
