Get RSI Period

[Mansour Mansouri]

Hello,

I want to get period of current RSI indicator. Does anybody know how I can get it in MQL4 or MQL5?

Thanks

You don't get anything. You set it when you put it on the chart.

            int startPos  = (int) StringFind(name,"(",0)+1;                       // or use 4 as it is clear where to start
            int endPos    = (int) StringFind(name,")",0);
            int rsiPeriod = (int) StringSubstr(name,startPos,endPos-startPos);
         }

Hello William,

I need to know what RSI period  is on the chart in my EA.

Do you know how we can put RSI on the chart within EA? We get RSI parameters from user and we put appropriate RSI on chart.

1. There is no generalized way to know what is on the chart. The human put the RSI on the chart. Only the human knows.
   
2. The EA has no eyes. It doesn't need anything on the chart. Add an input to your EA and let the human tell you.

 I want to do the same. Add an input to my EA and human tell me. But I do not know how to put RSI on the chart according to these inputs.

What part of “the EA has no eyes. It doesn't need anything on the chart” was unclear to you?

What about MT4?

Why did you post your MT4 question in the MT5 General section instead of the MQL4 section, (bottom of the Root page)?

Next time, post in the correct place. The moderators will likely move this thread there soon.
