Hello guys,
Recently someone told me there was a quite broad use of indicators that are derivatives of another indicators. E.g. One can use Bollinger Bands with the use of RSI data (instead of price data).
This guy told me that such combined indicators (derived on data of other indicators, previously derived on data of yet another indicator) are used by quants and smart investors.
Do you guys use such indicators? Can you confirm if such indicators are of any use? Any examples?
Thanks
