3.2 Mathematics of the Matrix: Pips, Lots, and Leverage
To become a professional trader, you must stop thinking about money in terms of Shillings or Dollars. Professionals do not say, 'I made $100 today.' They say, 'I caught 50 Pips using 2 Standard Lots.' You must learn the mathematical units of the market.
The PIP: Percentage In Point
Currencies move in incredibly tiny fractions. If EUR/USD moves from $1.1000 to $1.1001, it has moved by a single 'Pip'. A pip is the standard unit of measurement for a currency pair's price movement. For 99% of currency pairs, the Pip is the 4th decimal place.
The JPY Exception: The only major exception to this rule is any pair involving the Japanese Yen (like USD/JPY or GBP/JPY). Because the Yen is fundamentally valued differently (e.g., $1 = 145 Yen), the Pip in JPY pairs is the 2nd decimal place. So a move from 145.00 to 145.05 is a 5-pip movement.
Lots: How Much Are You Buying?
If you go to a wholesale market, you don't buy one grain of rice; you buy a 50kg bag. In Forex, you buy 'Lots'. A lot represents the specific volume of currency you are trading. Because currencies move in such tiny fractions (pips), you must trade large volumes of them to make any meaningful profit or loss.
There are three main lot sizes:
- Standard Lot (1.00): 100,000 units of currency. A 1-pip movement equals ~$10.00.
- Mini Lot (0.10): 10,000 units of currency. A 1-pip movement equals ~$1.00.
- Micro Lot (0.01): 1,000 units of currency. A 1-pip movement equals ~$0.10.
- Standard Lot (1.00): 100,000 units of currency. A 1-pip movement equals ~$10.00.
- Mini Lot (0.10): 10,000 units of currency. A 1-pip movement equals ~$1.00.
- Micro Lot (0.01): 1,000 units of currency. A 1-pip movement equals ~$0.10.
If you buy 1 Standard Lot of EUR/USD and the price moves in your favor by 20 pips, you make $200. If it goes against you by 20 pips, you lose $200. As a beginner with a small account, you should only ever touch Micro Lots (0.01 or 0.02).
The Power of Leverage
You might be wondering: 'If a Standard Lot is 100,000 units, how can I trade it when I only deposited $500?' The answer is Leverage.
Leverage is essentially a short-term credit line from your broker. If your broker gives you 1:100 leverage, it means for every $1 you have in your account, the broker allows you to control $100 in the market. With $1,000, you can control $100,000 (a Standard Lot).
Leverage is a double-edged sword. It amplifies your profits, but it equally amplifies your losses. If you abuse high leverage, a tiny 10-pip fluctuation against you will trigger a margin call, and the broker will automatically close your trades to protect their loaned money, instantly wiping out your account.
Self-Evaluation Check
1. If GBP/USD moves from 1.2500 to 1.2530, how many pips has the market moved?
2. You are analyzing USD/JPY and it moves from 150.10 to 150.15. How many pips is this?
3. If you open a trade with a volume of 0.10 (a Mini Lot) and catch a 50-pip move, what is your approximate profit?
4. How does leverage actually work in your trading account?
