Also not to let anyone down, here is my final tweak on the TDI indicator.

The signal is at signal line (red in picture) crossing the price line (green in picture).
Alerts should be close to on point.

I plan to nail it down with this set up....wishing luck to everyone.

ps: Again, esttemed mr.Mntiwana, maybe you can do a tweak on the volatility bands on the TDI, and than it's all tidy.

Setfile is in the ZIP.
