Run the tester over the specified range of years. Available data
runs from 1986 through 2012 for most screens. You may start at any
month of the year, but other than January can only run through 2011/2012.
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 & 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
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.
