Currencies are traded on a pip system. A pip is another word for a point in the currency trading arena. Traders are trying to capture points. Depending on the currency, each point is worth a different amount. For example, the British Pound is worth about $10 per point that is traded per lot. If you trade 1 lot and capture 40 points, you just made $400. If you trade 10 lots and capture 40 points, you just made $4,000.00, etc.
