StochRSI output

I am probably using this incorrectly, but the output I am getting from the StochRSI indicator seems more extreme than what I am seeing using the same values on other platforms.

In Zorro I am calling it as follows:

vars Prices = series(priceClose());
vars RSI_ = series(RSI(Prices,14));
vars Stoch_RSI = series(StochRSI(RSI_,14,3,3,MAType_SMA));

plot("StochRSIFast",rFastK,NEW,BLUE);
plot("StochRSISlow",rFastD,0,BLACK);

So I have a 14 period RSI, and am using this as the input data for the StochRSI indicator, also with a 14 TimePeriod, with a fast K and D of 3. I am plotting the rFastK and rFastD values.

See attached output from the GBPUSD daily charts for a similar period on both Zorro and TradingView for comparison.

Feed StochRSI() with Prices, rather than RSI_.

Thanks, Zheka.

I had tried that originally, but then thought I should create an RSI series for the relevant timeperiod I wanted to then feed into the Stoch....?

In any case, both Price and RSI look pretty much the same, and not what I'd expect.

Hi, did you ever solve your problem? I have a similar issue between the TradingView stochastic v the stochastic models offered via Lite-C. Is it possible to take the math from TradingView and create the indicator without using "built-in" stochastic models offered by Zorro? I believe the help in TradingView offers the equations.

Yes, you can write your own indicators. Read on:

As to my knowledge, tradingview uses the standard stoch formula. Nonstandard indicators had to be written by script. But this is normally trivial. The example in the tutorial is a particularly complex indicator.
