Please , a question about the timeframe of iCustom ,anyone can help?

 

Hello, i have a question about the timeframe of iCustom。what's it indeed in multi-timeframe?

For example,there is a custom indicator name MyIndicator in EA, and the timeframe is set to 30 mins,please see below。

iCustom( null, 30, “ MyIndicator ”, ..., int mode, int shift);

Now, i add this EA to 1 hour diagram. ok, now,the question is that if there is another indicator such as iMACD in MyIndicator,and the timeframe is 0,it means current time period.

double iMACD( null,0,.......)

In this scenario, EA works on 1 hour,MyIndicator works on 30 mins,For now, well then, what is the time period iMACD used ? 30mins or 1 hour?

any thought?

Thanks in advanced!
