The spread is the difference between the buy and sell price. So with an actual spread of 3 (regardless of what you have entered in your strategy), if your conditions are met at an asking price of 100 then that is what you will pay – but because of the spread your position at the time of opening is only worth 97.
As Grahal said, the spread you enter in your strategy is only for back testing. It has no effect on what happens in real or demo trading where the spread is set by the broker.
does that answer your question? or have i misunderstood?
