if you buy a share at 1,514.00 and it goes down to 1,513,00 then it goes up to 1,516,00 and then you sell it, would you have made a 2 point profit or just 1 point profit? and say i broght it and i wanted it to go up from (1,514.00)

You make 2 points in profit. Your profit/loss is alwasy calculated as your average cost basis versus your average sell price. It doesn't matter what happens in between. For the S&P 500 Emini, each contract would yield $50 per point in P/L, or $100 in the scenario you listed.

I agree with eztraders1.
