Fibos Expansion Help !

[lhDT]

Hi,

I would like to code a fibo expansion based on the last hi/low (tops & bottoms).
Fibo Expansion needs 3 points. I think it's a great tool to calculate profit & SL targets.

I don't have the formula with 3 points. Somebody can help me ?
Fibo expansion levels are -0.618 for SL, 1.618 TP1 and 2.618 TP2.
See attached chart (fibo expansion are orange lines)

Thanks for your help !

I've found below indicator yesterday, I can't understand the code, some I hope this can somehow help you if you fine tune it. (it doesn't draw the actual fib lines, but instead it calculates H/L from prev days etc..)
