**Chang Suk Chung:**

Hi, everyone,

I am developing expert advisor.

But there is an "invalid volume" problem in my coding.

Below is the method I learn and think at mql5 articles.

I am going to put above code into "on Init" function of my expert advisor.

Lot size of order at my expert advisor is 0.1 and volume is 0.01.

Is it right?

Please help me.

Thanks to everyone.
