Use a Points Only Test When Running a System Test on a Commodity.

The gain/loss amounts of a test are based upon the equity invested and the price change of the security.  The true gain/loss for a commodity trade is based on the dollar value you earn for each point you gain or lose in the commodity and the dollar value each point change is worth and the number or contracts you purchase.  A system test does not know the dollar value of each point or how many contacts you purchased so the gain/loss amounts will not be the true dollars gained or lost for the commodity trade. 

So when you run a system test on a commodity, you will probably want to run a Points Only test.  A points only test will calculate the number of points you gained or lost when you bought and sold, using your trading rules. Once you know the number of points you gained or lost you multiply the value that you know each point move is worth, by the number of points gained or lost to determine for yourself the amount of money the test would have made or lost for you.
