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.
