Differential in calculation result in broker vs mt5

New comment
 

Hi Guys,


I have made mathematical interpretation in one of my expert advisor, my issue is when I testing it on MT5 demo account the results are correctly placed, but when I testing it in my broker's demo account its suddenly changes it value, for example i bought 0.01 lot at 2750 and target it only 0.2 then it should come as a 2750.200, but in my brokers demo and real account its get changes, how can i solve this issue, I want same results as in MT5 demo and brokers demo, can anyone help? I am giving piece of code here,


 if(buyPositionCount == 1)
        {
            double tgtBuy_0_01x = ((entryBuy_0_01 * 0.01) / 0.01);
            double tgtBuy_0_01 = NormalizeDouble(tgtBuy_0_01x + 0.201, 3);
            obj_Trade.PositionModify(positionTicketBuy_0_01, 0, tgtBuy_0_01);
        }
        
        if(buyPositionCount == 2)
        {
            double tgtBuy_0_03x = ((entryBuy_0_01 * 0.01) + (entryBuy_0_03 * 0.03) / 0.04);
            double tgtBuy_0_03 = NormalizeDouble(tgtBuy_0_03x + 0.201, 3);
            obj_Trade.PositionModify(positionTicketBuy_0_01, 0, tgtBuy_0_03);
            obj_Trade.PositionModify(positionTicketBuy_0_03, 0, tgtBuy_0_03);         
        }
 
i do not see any spread in your calculation.

the spreads are different with each broker and mt5 demo. Unless mt5 demo and your broker has 100% same spread, then, your entry prices WILL be different.

Use the Search feature of this website for term "Spread". and go to link "Documents" on the left hand side of desktop site. You will see examples of how to retrieve the spread in realtime.

Besides the previous posts suggestions, in essence your code should also read the contact specifications for the symbol and then adjust accordingly.

Implement the following in your code to make it more robust ...
