This tutorial assumes you have already attached your Expert Advisor to your chart. For instructions on this, visit the tutorial "How to Attach Your Expert Advisor".
1. Confirm that your Expert Advisor is attached to the appropriate chart.
The Strategy Tester
3. The Strategy Tester will open on the bottom of the platform. Here's what the settings are for...
A. Use Date: if this box is checked, it will back-test only this date range. HOWEVER, it can only backtest data that you have available in your charts. Click on the chart you will be testing then click the "Home" key on your keyboard and it will scroll back to the first candle in your history. Hold the "Home" key down to download as much data as your broker will allow. The Strategy Tester cannot test data prior to this regardless of what your date settings are.
B. Visual Mode: This will place the Buy/Sell signals on your chart but it will take a lot longer to perform the back-test if testing a lot of data on small bars of 5-Min or less. The slide bar to the right of Visual Mode controls the speed of the test. Start back-test slow then slide right to maximum speed or it will take forever to run the test.
C. Period: Shows the time frame that you're testing
D. Spread: This shows the broker's spread that the back-test is using. At a 5-digit broker (most brokers) multiply your desired spread by 10 since it will represent points, not pips. So a 4 pip spread should be entered as 40. However, at a 4-digit broker, enter 4 for a 4 pip spread. A setting of "Current" uses the market's current spread. If back-testing on a weekend, manually enter your spread because some brokers widen their spreads on the weekends. This can make a huge difference in your back-test results so if something doesn't look right, check this setting. To see if your broker is 4 or 5 digits, open a EUR/USD chart and count the number of digits after the decimal.
E. Optimization: Leave this unchecked.
F. Choose "Control Points" for fastest backtest or "Every Tick" for the most accurate backtest. For "Every Tick" model, you will need to also download the 1 minute data for the same period being tested. CLICK HERE to download years of 1 minute data. The Roulette Trader EAs only open trades at the opening of a bar so using Every Tick model does not make a significant difference.
6. After the back-test completes, click the Graph tab to display the equity curve.
8. Click the Report tab to see a summary of the back-test results.
