Looking forward to teacher kvak making a Kalman filter (candles)(mtf) BT.mq4 version. Requirements: Auto adjust candle body width.

Infinite merit!

Hello.
I dont know how its close to MT5 version, but here it is.
Found some version here at FS and
make two version lines and candles.
Both have two state for coloring based on Kalman fiter slope or value of velocity is < > 0.
MTF with AHTF, price smoothing, arrows and alerts and button.
