How it works

When you create a stock screening strategy that contains all necessary criteria and the selected historical year for comparison, backtesting applies this information and simulates trades for every matched stock, based on each day of the selected year. It operates close prices only, or in other words, it performs end-of-day (EOD) screening to find eligible companies. Any matching stocks will be put into your virtual portfolio and any that are not will be ignored. Even if some stocks, however, do match the criteria, they will still be ignored if there are no vacant positions in the portfolio. Traders typically do not add a large number of stocks to their portfolio, because its purpose is to control risks (20-30 stocks generally suffice). Portfolio size can be specified along with other parameters during strategy creation. Also, if some stocks in the virtual portfolio conform to exit criteria, stop loss, or take profit conditions, the corresponding position will be closed. Users can specify the criteria for closing positions. In this case, stocks that were purchased earlier are sold and will be reflected in simulated trades. The position is then closed which allows for vacant positions in the portfolio:


Trading simulator iterates daily

During execution of the trading simulator, there can be a situation when the number of stocks meeting the criteria is more than the number of vacant positions in the stock portfolio. In this case, stocks will be added using the prioritization parameter. For example, if the parameter is set to Highest Average Volume value and there are two vacant positions in the portfolio, then only two stocks with highest average volume will be added by the trading simulator:






The trading simulator takes several seconds to perform the analysis. Testing results and a list of executed virtual trades are displayed on the backtesting report page.
