You don't need it to make money trading so don't waste your time looking for the perfect system with a 100% winning rate, just play the odds, manage your risk and you will be fine.
What I mean is not a 100% system. What I mean as the holy grail is a strict setup that you can consistently trade over and over again and produce a profit. Is it real? Does it exist?
You can consistently make money trading with a purely mechanical trading setup. Simple enough for you?
Example of a simple trading setup: Buy when the close is: 1: above the 20 and 50 moving averages AND... 2: higher than the 40 previous bars Do the opposite for short positions. Stop is the middle of the range of the 40 previous bars. Liquidate long position and take profit if two consecutive bars are completely below (or above for short positions) the 2 moving averages.
