I have tested deeply the (4 time frame Waddah Attar explosion nmc.exe), and unfortunately it repaints, it gave me a signal to go ahead and take a long trade when all the colors aligned ( the 4hr/D1/W1/MN), i traded AUDCHF at 03:59. i went to check the chart at 12:30, i saw that the signal disappeared and like no signal was given at all. !!

things like that will easily wipe your trading account.
