Pips, Lots and Position Size
Pips tell you how far price moved, lots tell you the size of the position, and position size determines how much that movement is worth in dollars.
Leverage and Margin
Leverage lets you control a larger market position with less capital. Margin is the amount set aside to support that leveraged position.
