Need help to convert formula

Hi, I need to replace iRsi in this formula with iStochastic.

double rsi = (iRsi(rwma,RsiPeriod,i,rates_total,0)-50)*0.5;

I don't know how to exactly set the iStochastic formula. I tried using this, but it doesn't work:

double rsi = (iStochastic(rwma,RsiPeriod,5,3,3,MODE_SMA,STO_LOWHIGH,i,rates_total,0))*0.5;

Could someone help me? Thank you...

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

What do you mean you "don't know how?" Perhaps you should read the manual.
iStochastic - Technical Indicators - MQL4 Reference
"Doesn't work" is meaningless - just like saying the car doesn't work. Doesn't start, won't go in gear, no electrical, missing the key, flat tires - meaningless.

Bogus call:

Your code	Documentation
double rsi = (iStochastic( rwma, RsiPeriod, 5, 3, 3, MODE_SMA, STO_LOWHIGH, //{ i, rates_total, //} 0 ))*0.5	double iStochastic( string symbol, // symbol int timeframe, // timeframe int Kperiod, // K line period int Dperiod, // D line period int slowing, // slowing int method, // averaging method int price_field, // price (Low/High or Close/Close) //{ int mode, // line index //} int shift // shift );

Your code

Documentation

double rsi = (iStochastic(
   rwma,
   RsiPeriod,
   5,
   3,
   3,
   MODE_SMA,
   STO_LOWHIGH,
//{
   i,
   rates_total,
//}
   0
))*0.5

double  iStochastic(
   string       symbol,           // symbol
   int          timeframe,        // timeframe
   int          Kperiod,          // K line period
   int          Dperiod,          // D line period
   int          slowing,          // slowing
   int          method,           // averaging method
   int          price_field,      // price (Low/High or Close/Close)
//{
   int          mode,             // line index
                                               
//}
   int          shift             // shift
   );

I assume STO_LOWHIGH is zero.
You have i and rates_total, the call has only one argument and neither are MODE_MAIN, or MODE_SIGNAL.

On MT4: Unless the current chart is that specific pair/TF referenced, you must handle 4066/4073 errors.
