This indicator is just hybrid of super trend and VRSI level script (open script at my page) just another super trend ( i made so may variation of this that I need to find new ideas:)) the signal controlled by rsi length / and RSI high or low (here set to 35 and 70 ) and regular control of Super trend
initialy i wanted to make it as a filter script for other script that I am working on but since signal look actualy not so bad so i put it as stand alone type of version try to find best setting for your needs alerts included btc
