How to code indicator applies on another indicator?

[luckyvictor]

In MT5 chart, when you drag an indicator, you can choose to apply from the standard price values, for first/previous indicator.

In terms of coding, how can this be achieved?

E.g I want to apply moving average on another moving average, or MACD on another MACD.

I tried with the following code but rsi 3 just return zero all time.

RSI_14[i]=iRSI(Symbol(),0,14,PRICE_CLOSE,i); 
RSI_3[i]=iRSI(Symbol(),0,3,RSI_14[i],i);

This is MQL 4. In MQL 5 it works different, you first need to obtain a handle to the indicator and then use CopyBuffer to read out the indicator data.

And you can pass the first indicator handle to obtain a second indicator handle.

Can you give me an example? Thank you so much!

int RSIonRSIhandle=iRSI(NULL,0,Period,RSIhandle);

Like so maybe. See the reference manual. https://www.mql5.com/en/docs/indicators
