Fred,
But..Thomas' code explicitely sets all trade prices to OPEN price with zero delay.

Jim,
Although it's not possible to trade with delay 0 on the open it is
certainly possible and feasible to trade with delay 0 on close. One
may not get 100% of the signals correct but the small amount of
errors will for the most part balance each other out. I do this
EVERY day.
