OPEN-SOURCE SCRIPT
Updated Bollinger Bands By CryptoLawyer1

This is a simple cross under/over script, if the close is lower than the lower band SELL, if it has crossed above buy/close short
the script is equipped with a 55 SMA signal filter for less noise, you can customize the lengths based on the pair and time frame, i would recommend using higher lengths on lower timeframes and lower length on higher time frames, example : 1Week: 13L, 2Hours: 55L, 15Minutes: 200L
Important Note ⚠: the ideal signal is a trend reversal and not a continuation, same goes for long and short signals, you should take short signal if the price has been going up and the bands are green for a long enough time, and the high's have crossed over the upper bands at least 3-4 times same goes for long, you should find a down trend that has been going on for a good enough time, so in simple words search for reversal not continuation signals, if you have any questions feel free to ask, happy trading!
