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.
