But it did not take a dollar out of the person on the other side of the transaction's pocket. Again, my only point.

That is incorrect.

Every dollar Trader B made came out of Trader A's pocket. Look at what happened:

Trader A was up 96 points as of Jan 8th at 10 AM. If he had exited then, he'd have 96 points in his pocket. But he stayed in trade.
At 130 PM on January 8th, Trader A was up only 76 points, when he exited his trade.
20 points came out of Trader's A pocket between 10 AM and 130 PM. (Trader A became poorer by 20 points during this time. It was open profit he lost, but he still lost that amount).

The money left the pocket of Trader A and went into the pocket of Trader B.

Did both traders exit their trade with profits? Yes. Perhaps that is what I should have said - it is possible for traders on both sides of a trade to be profitable. It is also possible for traders on both sides of a trade to lose money on their trades. That is all I am trying to point out.

OK, but remember you were trying to refute this statement:

"when you win, someone loses. You cannot win in trading without taking what could potentially be food out of someone else's mouth. "

That is exactly how futures works - transferring wealth between parties.

I think we've beaten this horse enough, sorry to all for this.
