Get a warning message from Pinecoders about description. So I updated it.
English is my second language. Sorry for any typos or wrong grammars.
This script display stoch crossover/crossunder as candles.
K>D then display Green bars,
K<D then display Red bars.
It can not be traded directly. You can use these candles to watch the strong/weak trend or reverse.
I normally use higher timeframe to watch it. I am trading 15 min, so I will watch 1 hour chart.
