Thinkscript for Slow Stochastics backtesting Strategies

[KarmaSenge]

Does anyone have a Slow Stochastic Strategy thinkscript for backtesting? I see in the ToS platform that they have one for MACD (MACDstrat) and RSI (RSIstrat) and many others but not one for stochastics. Anyone have one? Or can someone make one?

Thanks
