The Value of Back Testing in Trading

Seasoned traders know exactly why trading plans are needed but not all of them mention the value of back testing. Neophyte traders should get right into this even before they dive into any of the available markets. There is no chance that you can make consistent profits without tested systems.

For new traders, the phrase may seem a bit foreign. There is nothing difficult to understand about the term though. The simplest way to look at it is that testing involves running an existing system through historical information. The end result is an assessment of whether a system will work well or not in previous trading conditions.

Obviously, back tests are advantageous for several reasons. One main benefit to it is that traders are given a direct idea of whether a system is likely to give profitable results or not. The potential profitability of a trading system is a clear point of interest for traders mainly because there is no point in adopting a system that is likely to fail. Despite the fact that only historical data is involved, you can still effectively test a system. The situations that have unfolded in the past in the markets will probably have future parallel occurrences.

This isn’t just all about making good profits once. A systematic and scientific back test can offer some insight on the possible future consistency of a trading system. Furthermore, you can also efficiently gather data on what needs to be improved in your plan. Aside from custom plans, this will also come in handy when you tweak set plans such as the Nicolas Darvas trading system. A good example is the process of allocating capital. Testing can give you a clear guide on how and where chunks of your capital should be placed.

Technical back testing certainly has concrete advantages. The benefits however can cross over the less tangible elements. One benefit of testing for example is that it promotes the development of trader confidence. This is something every trader should have because without it, trading will become unsystematic. There will always be the inclination to jump from one system to another without hope of making consistent gains. That’s almost as if investments were made without a plan.

What this all means is that back tests have a significant effect on individual trading psychology. The effect of a successfully concluded test is that decisions no longer become the results of half hearted guesses. Since you are certain that your system is effective, you don’t have to wonder where to take your position.

Charting packages typically have their own testing tools or software. Many of these however fail to deliver the best results. Some testing tools in packages for example implement tests on individual assets, taking one security and the total capital across the procedure. This is hardly a reflection of actual trading situations because many traders have portfolios of securities. A good testing facility should be able to consider multiple securities in one test run.

There is no doubt that back testing is necessary especially if you decide to download Metastock. If you want profits to keep on coming, you need to consider tackling this first. Pick a testing tool that has a proven and effective track record.
