This might be the best i ever came across!
As it only repaints the 2. latest (including the one currently forming) you can base a tradingplan on going long or short everytime the 3rd stick is forming with the 2 privius beeing a new color.
Every dag at 00:00 GTM, you go to the daily chart EURUSD. You see that the 2 privius sticks changed from Red to Green (bullish). Now, place a Long and check back every day the market is open at 00:00 GTM and wait for 2 red sticks to form and close ur position + enter a short.
I backtested this on the EURUSD daily chart for 2010.
The results were quite nice:
Total trades taken: 17.
Total trades win: 13.
Total trades los: 4.
Biggest win: 1334,1 - Spread.
Biggest loss: - 60 pips - Spread. (about 62,5)
Well it depends on what you are using the Fisher for. As for me, its one of my best indicators and a leading indicator combined with price action. Suprised? I have used it to develop strategies. Dont bother yourself with whether the fisher repaints or not. Honestly you can search the internet for a non-repainting Fisher but the truth is that you wont find any! See the Fisher as a momentum indicator and you'll have a better understanding of how to use it! Also you can have 70-90% win rate by spotting divergences with the Fisher! Ppl say all sort of things about the Fisher but when you study it and find a way to use it youll be amazed. So i dont care whether it repaints or not! it's what i use the indicator for that matters.
