General instructions

Run the tester over the specified range of years. Available data runs from 2003 through 2016 for most screens. You may start at any month of the year, but other than January can only run through 2015/2016.

Stocks are picked from the screens every holding period (between 1 and 120 months) and held for that period.

Instead of selecting from the available screens, you may choose to enter codes from any of the backtesters to create hybrid tests. Simply copy the link listed at the top of a run and paste into the form. Also see the backtester code guide.

If you want to simulate actual trading, you can enter more parameters in the trading simulator.

You may give your backtest a name for convenience. If you use this backtest code in other testers, its name will be shown instead of a full description.

Screen of Screens Backtest instructions

Choose which screens to select the stocks from. You may limit choices to stocks that appear on some minimum number of screens or unique screen categories (i.e. Keystone, RS, etc.). Note that the concept of "unique" only applies to a limited subset of the predefined screens.

The stocks in each screen are ranked, counting down from the first stock to the specified position (or all stocks if no position is specified). The first stock gets max points (max defaults to position), the second max-1, and so on. The totals for each stock are then sorted, and the highest limit stocks are chosen. In the case of a tie, a secondary sort is done by looking at each screen in sequence, and selecting the stock that appears first.

Another popular SOS tool is the Saucer, which allows you to generate a list of current rankings for SOS combinations.
