Thanks, I am learning everyday.

I don't know MQL much and For Zorro I am still trying how to code "Lot" correctly.
and "IsTradeTime".

Could you please a simple code for them?

In MQL, I don't know what they mean - "RangeFromComment()" and "ND()"

About this code, Do I need to use a imcomplete bar in this script?
if(bt != Time[0]) {
bt = Time[0];
}

These type of volatility EAs is so popular now.
What do you think of them? Are they really profitable for long term?
