How to Backtest an EA on MT4
Posted 1 year ago | 2:00 AM | 28 March 2014 11 Comments
I’ve received several comments from human traders asking how I am able to run backtests using expert advisors on the MT4 platform. It has come to my attention that newbie traders could appreciate a quick how-to on using the handy-dandy Strategy Tester feature of MT4 so I decided to write a quick guide to help y’all get started.
Before we get started though, make sure you’ve finished the School of Pipsology lesson on How to Use MetaTrader 4. This should help you out with the basics of installing an EA as well.
Once you’re done with that, open the Strategy Tester panel by clicking on View then selecting Strategy Tester.
A panel should magically appear on the bottom part of your MT4 platform. Choose the EA you installed from the Expert Advisor choices.
Set the currency pair you want to run the backtests on and the appropriate period by clicking on the menu beside Symbol and Period. Specify the backtesting period by setting your preferred dates and making sure the Use Date box is checked.
In this example, I’m running the backtests using EUR/USD’s 15-minute time frame from February 1, 2013 to February 1, 2014. To ensure better modeling quality. select the Every Tick option for the model and select Current for the spread.
You have to make sure that your price history data is complete to avoid mismatched chart errors on your trading log
or have a modeling quality that’s lower than 90%. To do this, head over to the History Center under Tools or simply hit F2 on your keyboard.
From the pop-up window, double-click the currency pair you’ll be running the backtests on and check if the time frame you selected is included in the database. If not, select the time frame and click the download button below.
It is recommended that you include the 1-minute tick data for more accurate backtest results, but this might take a lot of space in your hard drive and based on this robot’s experience, it could lead some programs to crash. Don’t say you haven’t been warned!
Once the history data is complete, you are finally ready to run the backtest. Just hit the Start button on the right-hand side of the panel and let the number-crunching commence!
After a few seconds or minutes (depending on your backtesting period and the speed of your processor), you can be able to view the results through the Graph or Results tab at the bottom of the Strategy Tester panel. As I always mention though, make sure you take these numbers with a grain of salt as past performance is not always indicative of future results.
I hope this basic tutorial makes forex robots a little less intimidating for newbies out there! If you have any questions, just post ’em in the comment box below. And for the expert traders around, I’m counting on you to help beginners out!Source: www.babypips.com
