I developed a little trick that might seem trivial, but it is very important. Simply put, anytime to you put a trade on, assume that the trade is going to be a loser. No matter how much analysis, how many supporting factors, or how perfect the pattern is, assume that the trade will lose money. This creates a profound shift in your focus because, rather than searching for and possibly discounting contradictory evidence (which can sometimes be as simple as “I just bought and now it’s going down…”), you will be open to and will readily accept contradicting information. Of course you will, because you assumed the trade was wrong to begin with. When you find confirmation for the trade, it is almost a pleasant surprise. Shift your thinking into this mode, and you will be much less likely to overstay your welcome in suboptimal setups that are not working out–you’ll be far more likely to do the right thing, which is usually to pull the plug on the trade (time stop) and look for a better opportunity.
Now, there’s another piece to this puzzle. A lot of writers focus a lot of attention on confidence in trading, and this is important, but it is a different kind of confidence. You must have confidence in your method and know that a profit is virtually assured over a large enough set of trades, and be able to separate this knowledge from the outcome of any one trade which is, more or less, a coin flip.
