Dimitris,
Wouldn't you expect T3(3) to respond more quickly and with less overshoot
than DEMA(20) or TEMA(20)?
If you graph DEMA(3) and TEMA(3) against T3(3) then DEMA/TEMA respond much
better.
Or do I not get it?

> Let us suppose a stock goes from 100 to 110 in one day.

> For DEMA/TEMA period=20, we need Ti3 periods x=4 and x=7
