This is the beautifully coded TTF (Trend Trigger Factor) Pre-Smoothed by Mladen which he also kindly added (newer drop down box) Multi-timeframe mode + Interpolation.

Slightly different to the well-known TTF New which was posted by Moderator Mntiwana, the "Pre-smoothed" version seems to give slightly earlier signals when comparing the two. Both are outstanding indicators which work very well.
