TP as a percentage between the first and the last trade of the series
I suggest adding an option to the Fibo filter, when the first and last trades in the martingale series are used as extremes.
Why might this be useful?
There are scenarios when a very fast rollback occurs
Any indicators are very late during such rollbacks, and I want to use % fibo retracement as one of the exit filters
Example:
This will allow you to make extra profit in such equity surges:
Maybe if you share how you have it set up, you could set "close in profit" and open a martingale on each new candle.
