Take a trade on candle high above (long) and low below (short). I've made few modification from Mr.Johnman scripts for Better results for Indian traders. Thanks to him.
For Target and stop loss ;
Open Renko chart from your broker trading platform and find the Renko bar settings, here you'll find "Set Range". Those value will be your SL & Target.
Make sure take a trade above / below candle once colours appears.
