The reason that most traders fail is and I guarantee this, note the use of the word guarantee. It is the simple fact that they have not back-tested their system on a minimum of five years of data and preferably ten to fifteen years on all the currencies or instruments that they trade.
Yeah yeah I here you saying it now,
- I don’t believe in back-testing I only believe in forward testing
- Its very hard to to back test my system
- I am not a computer programmer I can’t do that
and on and on it goes. It is very easy to find an excuse to not spend the hundreds of hours that are involved in back-testing and finding a profitable and consistent system. But you will sit there for say four to ten hours a day demo trading or even worse, live trading a system that you have absolutely no idea at all whether it even has an edge let alone can produce profits consistently and inevitably losing money.
I ask you to ask yourself these questions and answer them truthfully. Note: this will probably hurt.
- How long have I been trading
- Do I produce consistent profits or am I even profitable at all
- Do I know my expectancy
- what is the maximum this system has drawn down before, 10,20 40% ??????
- What is the maximum number of losing trades this system has produced in a row previously
- What is the longest draw down period that this system has produced before
If you do not know the answers to all these questions what chance of survival in the trading game do you have.NONE!!! When trading any system without these answers you can not even realistically calculate your position size as this has to be measured accordingly with your back-tested results in regards to maximum no of losing trades and absolute draw-down.
Even if by some chance you are trading a profitable system your chances are still very limited of being successful. Imagine risking 3% per trade on a system that has previously produced ten losing trades in a row. I ask you, could you really handle that psychologically? I doubt it, when your account is bleeding like that it is extremely hard to think clearly let alone take another trade, and then another trade. Now if you know this information you can gear your risk accordingly and say risk 1.5%. A 15% draw-down will be much easier to handle than a 30% draw-down. That is why back-testing is of the absolute most importance, because it gives you the information to gear your trading around and also the ability to set some realistic goals.
Once you have defined your edge you can then set your risk parameters accordingly, you will be armed with the information of draw-down expectancy and how many consecutive losing trades you can expect. This does not guarantee that you will only have x number of losing trades in a row, as markets do change and results will vary. What it does do though is arm you with a good idea how your system performs over time and on different markets. This information gives you the confidence to keep trading through the tough times.
This is where I use Forex-Tester. I have now literally spent hundreds of hours testing my ideas and will spend hundreds more I have no doubt. This software makes it possible to literally test any of your ideas on any instrument and, you need no programming skills at all. Where it really excels is when you are a discretionary trader and your systems is not able to be programmed even if you have the skills.
In closing if you have not back tested your system and you are not profitable in your trading stop gambling now! That is what you are doing if you have not back-tested, GAMBLING! Believe me a few weeks spent back-testing and PROVING you have an edge will be the best thing you will ever do.
Good luck but believe me you won’t need it once you are armed with the right knowledge.
