Help needed with EA coding

Hi guys,

can you help me please? So I try to write own EA.
When I change the size, it changes the number of trades. For example.
I did backtest in tester graph (MetaTrader) for the last 5 years and got 400 trades with defined lots 0.01
And when I set lots 0.09 and made backtest again for the last 5 years got only 100 trades....

I do not understand how size affects the number of trades...


double Size = 0.01;

ticket = OrderSend(Symbol(),OP_SELL,Size,Bid,0,Bid+SL,Bid-PT,Text,Magic_number,0,Red);

Do you have any experinces with this problem please?
Thanks, have a nice day.

Sorry for my english ) So I hope that you understand...

here .... trades with size 0.01 and trades with size 0.09 .....

For size 0.01 to 0.08 are all results the same. Total trades, ProfitFactor etc.

Only for SIZE 0.09 are results different........

Without seeing the code, it is impossible to answer.
What are you seeing in the journal?
Could it be that you don't have enough margin to place the trades with a higher lot size?

Thank you very much....not enough margin is the problem for missing trades with a higher lot size.... For size 0.09 it only took trades where is 1.1000 and lower price...
