How to Backtest Automated Forex Systems
Automated forex systems are a great boon for forex traders. The ability to always be trading without the need of your presence is a great way to increase your profitability when trading forex. However, getting the wrong automated forex system to trade can cause major lose.
That is why it is important to backtest your automated forex system before you use your trading capital. However, you need to be able to do proper back testing for you to get the most out of your system.
1. Use Proper Forex Software for Backtesting
If you are going to risk thousands of dollars in forex trading, then you can afford getting proper forex back testing software. It is not enough to get software that is does basic testing. A forex trader needs to invest in forex software that is reliable and whose results can be verified. Get the proper forex trading tools and you may never need to worry about the viability of your forex trading system.
2. Get enough Forex Trading Data
The forex market is ever evolving and there is a need to test your automated forex strategy in different forex trading environments. There are a lot of forex data providers who provide such data for free. Your forex broker can also be a good source for such data.
Other than just the quantity of the data, make sure that your source also has quality data. If you test your automated forex system on quality and enough data, your chances of your back testing results being replicated are higher.
3. Do not Over-Optimize
Every time you change the parameters of your forex robot, you are likely to get unreliable results. Over optimizing or curve-fitting a forex system to give you better results on unrealistic parameters will give you a forex trading system that only works on paper but not in the real world.
Curve fitting normally occurs when the forex trader is using too many parameters. Try and keep the automated trading system as possible. If you create a simple forex robot and it shows profitable results on back testing, then it is more likely to work than a curve fitted forex system.
4. Adequately Test Your System
I have seen automated trading system that only work in one currency market. Most of the time such trading systems have been curve fitted. Before you trade your own funds in any forex robot, ensure that you have back tested the system on different time frames and also different currency markets.
The more time frames an automated forex system is profitable, the more likely it will work in a real environment. I have found that the best automated systems are the once that confirm that a trade is on in a higher time frame as well as in a lower time frame.
