For every style of trading, there will be a "perfect" market environment. When the market is aligned to the strategy that you are trading, every trade will work itself out smoothly, losses will be far and few between, and you will feel on top of the world as you watch your profits accumulate!
However, sooner or later the market environment will shift, if ever so slightly, and losses will once again begin to appear.....
This constant cycle from "zero" to "hero" and back to "zero" is why so may traders struggle and fail.
Understanding how to "beat" the Payout/Payback cycle is critical to long term consistency and success as a trader.
