I primarily use TSI (7,4) and TSI (25,13) for daily charts and change these periods for other chart frames. Having variable periods will give a lot of flexability.

TSI is a great trending and signal indicator. When starting to trend, it indicates a change in stock direction is underway or about to change. When it crosses zero, it reinforces the stock trend.

Being able to search TSI in protrader and plotting it on graphs is very powerfull.
