Tip #24: Know When It Doesn't Work
When you have a system or an idea, you must also know when it doesn't work. This concept is just the logical extension of the last tip of giving up on a good idea because you think it doesn't work. When you've researched something well enough to know 1) you are not getting the performance you want and 2) the reason you are not getting that performance, then you've made an important step in knowing that something doesn't work. Usually, the knowledge of why something doesn't work will also give you important knowledge of what to pursue next.
For example, let's look at the idea of Maximum Adverse Excursion (i.e., the idea that losing trades don't go too far against us). This gives you an idea for limiting your stops, but when you try to apply it to your trading you may find some problems. Some profit increase does occur, but this may not be that significant for you compared to the complexity of the MAE addition. The reason that MAE doesn't work is because 1) some losing trades exit at the MAE when they would have exited at much less of a loss had more room been given by a larger stop and 2) some big R-multiple winners are cut off. Since re-entry isn't allowed, those big winners are never realized. These two reasons totally cancel the effect of increasing the potential R-multiple of those winning trades that are realized.
You might take this concept and decide that's all you want to do with it. It didn't work and you know why. That's fine.
On the other hand, you can also use the reasons for “failure” as logical stepping points for your next research idea. For example, I noticed that in the few cases where big R-multiples are cut off, a re-entry signal will almost always catch them. When you do trading research, and you determine why something didn't work, it will always give you a reason. This reason could point you to areas that could give you much more profitable results.
