Writing Your Trading Rules

Writing-Your-Trading-Rules The first thing that needs to be done is that you must have objective or mechanical rules to enter and exit the market. This step is necessary to create a base of your strategy and whether or not the system matches with risk tolerance, portfolio size, money management techniques, and several other factors. Once you have established rules for trading, you must write to them as buy and sell rules in AmiBroker Formula Language.

Backtesting

Backtesting To Backtesting in AmiBroker, you need to click on the Backtest button in the Automatic analysis window. Ensure that you have typed the formulas which contain buy and sell trading rules. Once the correct formula is entered, AmiBroker starts to analyze symbols according to trading rules and generates a list of simulated trades. This process is rapid in terms that you can easily backtest thousands of symbols in a few minutes. There is a progress window that will show the estimated completion time. If you wish to stop the process at any given point in time, click on the Cancel option in the progress window.

Analyzing Results

Analyzing-Results When the process is completed, you will be presented with a list of simulated trades in the bottom part of the Automatic analysis window aka the Results pane. Here, you can examine when the buy and sell signals occur only by double-clicking on the trade in the Results pane. Post this, you are presented with raw or unfiltered signals for each bar where buy and sell conditions are met. If you wish to see only a single trade arrow (opening and closing currently selected trade) you are required to double-click a line while holding the SHIFT key pressed down. The other option that you can choose is the kind of display by choosing the appropriate item from the context menu which appears once you click on the results pane with a right-click. In addition to the results, you will also be provided with detailed statistics on the performance of your system by choosing the Report option.

Changing Your Backtesting Settings

Changing-Your-Backtesting-Settings Backtesting in AmiBroker makes use of predefined values for performing its task including portfolio size, and periodicity, i.e. daily/weekly/monthly, amount of commission, type of trades, price fields, interest rates, and so on. These settings can be altered by the user settings window. Post changing the settings, you must remember to run your backtesting if you wish the results to be in sync with the settings.

One requires extensive training before using the analysis and charting tool. Even though AmiBroker has quite several features and tools, that make the trading process safe and satisfying. We are hoping that shortly AmiBroker will become popular among non-technical users as well. Till then, keep trading!
