Margin Leverage in Futures

["Rick Parsons" <RickParsons@xxxxxxxxxxxxxxx>]

I saw this comment posted:

"4) I understand from the manual and onscreen
help that users who trade futures contracts
are encouraged to do points only tests
because of the challenge of accounting for
margin leverage in the futures contracts."

Could someone explain what the problem is and specifically how this affects
system tests?
If I use margin in the system tests, are the tests overstated or
understated?

Thanks,
Rick
