Without a doubt one of the easiest and also best ways to start stacking the odds in your favor is to start making trades that are inline with the trend.
The simple reason for this is because when trading with the trend you are trading with the obvious direction that price is currently moving. Whilst that does not ensure that price will continue moving in the same direction, it does increase your trades odds of being a winner.
The other reason is because trends can last for long periods of time. Unlike other markets such as ranging markets where price is chopping up and down, a trend can make an extended move in one direction for a long period of time.
This gives you the chance to use a smaller stop loss and make far bigger winning trades.
