OPEN-SOURCE SCRIPT
Updated Bollinger Bands Trending Reverse Strategy

Welcome to yet another script. This script was a lot easier since I was stuck for so long on the Donchian Channels one and learned so much from that one that I could use in this one.
This code should be a lot cleaner compared to the Donchian Channels, but we'll leave that up to the pro's.
This strategy has two entry signals, long = when price hits lower band, while above EMA, previous candle was bearish and current candle is bullish.
Short = when price hits upper band, while below EMA, previous candle was bullish and current candle is bearish.
Take profits are the opposite side's band(lower band for long signals, upper band for short signals). This means our take profit price will change per bar.
Our stop loss doesn't change, it's the difference between entry price and the take profit target divided by the input risk reward.

Release Notes
Didn't adjust the math behind the stop loss in the long entry position whereas I did in the short position. Basically halving the risk reward ratio to 0.75%, that was not intended and is fixed now.Open-source script
