There are no buffers (nor mode) for levels - of any indicator

Thanks for your answer

I need use it in my EA for example when

ExtPosBuffer

go under 30 line or any other custom line??

and is it true blue line mode ExtPosBuffer and buffer 1

and red line mode ExtNegBuffer and buffer 2 ?

Thanks again

If you are using normal RSI, don't worry about buffers and iCustom. Just use iRSI.

   if(iRSI(_Symbol,PERIOD_CURRENT,14,PRICE_CLOSE,0) < 30)

Thanks so much , this is work i think

but why i use

(iStochastic(_Symbol,PERIOD_CURRENT,5,3,3,MODE_SMA,STO_LOWHIGH,0)<20)

as insdroduction https://www.mql5.com/en/docs/indicators/istochastic and like your code compiler has error!

and another question how can i use this method for another indicator that don't have anyhthing like these indicator https://www.mql5.com/en/docs/indicators

Thanks again

and how can i use fall or rise line with degree!

for example in Stochastic say if blue line over red line and under 30 and both rise with over 10^ do it ...

?

is this true for blue line over red ?

double indi_5_Lo(string iCustomName, int iCustomMode, string SYMBOL, ENUM_TIMEFRAMES TIMEFRAME, int SHIFT)
{
double retval=iCustom(SYMBOL,TIMEFRAME,"Stochastic",  "ExtHighesBuffer"  ,2,0);
        
        return(retval);
}


double indi_5_Ro(string iCustomName, int iCustomMode, string SYMBOL, ENUM_TIMEFRAMES TIMEFRAME, int SHIFT)
{
double retval=iCustom(SYMBOL,TIMEFRAME,"Stochastic",  "ExtLowesBuffer"  ,3,0);
        
        return(retval);
}
if (indi_5_Lo>indi_5_Ro)

and what i should do for another questions ?

Thanks
