This is a modified RSI version using as a source a big length(50 candles) and an average of all types of sources for candle calculations such as ohlc4, close, high, open, hlc3 and hl2.
In this case we are going to use a 0-1 scale for an easier calculation, where 0.5 is going to be our middle point.
Above 0.5 we consider a bullish possibility. Below 0.5 we consider a bearish possibility.
I made a small example bot using that initial logic, together with 2 exit points for long or short positions.
