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.
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.
