I have tested this code in MT4 build 788 in both ECN and normal accounts, its ok in both cases. What problem exactly do you get?

You have to normalize your volume, nothing to do with ECN or not.

i have small mql knowledge. can you help me for edit it?

[Dr. Trader]

You have to call function NormalizeDouble with first parameter - your volume, and second parameter - digits in lot, usually 2 or 1. This will make sure that your volume has only two decimal digits. Its similar to round, and must be mandatory used for all volumes and prices before OrderSend.

Vol = NormalizeDouble(Vol, 2);

Also, make sure to do the same with your order price, stoploss, takeprofit:

double orderPrice = Ask;
double orderStoploss = Ask-0.001;

orderPrice = NormalizeDouble(orderPrice, _Digits);
orderStoploss = NormalizeDouble(orderStoploss, _Digits);

 

Usually I use following code to make sure that volume is setup according to broker settings:
