The fact is, most traders blow out their trading accounts either from risking too much money per trade, trading when no high-probability edge is present (over-trading), or a combination of the two. They forget about the FACT that they cannot make money on every trade, they are going to have losing trades, and that they never know what will happen on any one trade. Sure, you need to stay true to your trading plan and only take valid instances of your trading edge…so every trade you take IS important, but the point I am trying to make is that no one trade is going to make you a successful trader.
