I think: Take !step ehlers optimal tracking filter (mtf + arrows + alerts + candles + btn) as the axis to make a dynamic Fibo level line (5 dynamic Fibo level lines on the axis and below the axis):

#define level1 0.236
#define level2 0.382
#define level3 0.5
#define level4 0.618
#define level5 0.764

That is, replace Channel with Fibo.

May be good for trading.
