Conversion of built-in indicator Stochastic RSI from Pine (Tradingview) to MT5 EA

Conversion of the built in indicator with exactly the same input parameters from Pine inTradingview to MQL5 for MT5. This indicator is going to be a part of an EA and as such I will need to be able to use and change the input parameters.

The code from Tradingview is freely available and looks like this:

//@version=4
study(title="Stochastic RSI", shorttitle="Stoch RSI", format=format.price, precision=2, resolution="")
smoothK = input(3, "K", minval=1)
smoothD = input(3, "D", minval=1)
lengthRSI = input(14, "RSI Length", minval=1)
lengthStoch = input(14, "Stochastic Length", minval=1)
src = input(close, title="RSI Source")
rsi1 = rsi(src, lengthRSI)
k = sma(stoch(rsi1, rsi1, rsi1, lengthStoch), smoothK)
d = sma(k, smoothD)
plot(k, "K", color=#0094FF)
plot(d, "D", color=#FF6A00)
h0 = hline(80, "Upper Band", color=#606060)
h1 = hline(20, "Lower Band", color=#606060)
fill(h0, h1, color=#9915FF, transp=80, title="Background")

I've tried using some StochRsi from MT5 but it doesn't have the same result as Tradingview I need it to be exactly the same.
