This is the only Quantitative type indicator I can find on TradingView (which means it uses automated back testing to determine probability in a mathematical way), although there could be some I just haven't seen them.
This indicator back-tests ALL of the data, calculates the length of all past trends, and does a statistical analysis of trend changes at different levels. The more recent data is more accurate as it learns as the indicator goes along.
These levels can be used in regression to the mean trading, as it gives you an idea of the statistical likeliness of a trend change or pullback occurring in each zone. An average trend length is a very good point to enter when trading a pullback within a trend, although without a complex analysis like this it would be impossible to determine where that is.
PM me for access, and more details on strategies that can be implemented using this indicator.
