This script is, yet again, another mean reversion indicator. When the trend index touches the upper / lower bands, there seems to be a decent probability that the market might reverse at that area. However, I do emphasise on exercising caution when trading against the current wave of the market as there are instances where the trend index extends past the upper / lower bands for a prolonged period of time. However, in a non-trending semi-consolidated market, this script seems to do quite well for itself. Enjoy!
