Measuring the Market: Pips & Points
Unlike traditional stock markets where prices are measured in Dollars and Cents, the Forex interbank market measures price fluctuations in Pips (Percentage in Point).
For most major currency pairs (like EUR/USD or GBP/USD), a Pip is the 4th decimal place. For pairs involving the Japanese Yen (like USD/JPY), the Pip is the 2nd decimal place.
- EUR/USD Example: If the price moves from 1.1050 to 1.1051, the market has moved exactly 1 Pip.
- USD/JPY Example: If the price moves from 145.50 to 145.55, the market has moved exactly 5 Pips.
Position Sizing: Lot Mechanics
In Forex, you do not buy "$100 worth of EUR/USD." You buy in standardized batches called Lots. The Lot size you choose determines exactly how much money you make (or lose) for every single Pip the market moves.
| Lot Type | Volume (Units) | MT4/MT5 Input | Est. Value Per Pip |
|---|---|---|---|
| Standard Lot | 100,000 Units | 1.00 | ~$10.00 per Pip |
| Mini Lot | 10,000 Units | 0.10 | ~$1.00 per Pip |
| Micro Lot | 1,000 Units | 0.01 | ~$0.10 per Pip |
Example Scenario: You execute a Buy order on EUR/USD with a 0.10 Mini Lot. The market moves 50 Pips in your favor. Your profit is: 50 Pips × $1.00 = $50.00 Profit.
Margin & Leverage Deployment
Currencies do not fluctuate by 20% a day like cryptocurrencies; they move by fractions of a percent. To make significant profits from these tiny movements, brokers offer Leverage.
Leverage is essentially a loan from your broker that multiplies your purchasing power. It allows you to control a large $100,000 Standard Lot position with only a fraction of that amount in your account. The required capital you must have locked in your account to hold the trade is called Margin.
| Broker Leverage | Trade Size | Required Margin (Your Capital Locked) |
|---|---|---|
| 1:1 (No Leverage) | 1 Standard Lot ($100k) | $100,000.00 |
| 1:100 Leverage | 1 Standard Lot ($100k) | $1,000.00 |
| 1:500 Leverage | 1 Standard Lot ($100k) | $200.00 |
As you can see, higher leverage allows you to open massive positions with very little money. However, if the market reverses, your losses are also calculated on that massive position size. Leverage does not change the value of a Pip; it only changes how much Margin you need to open the trade.
Margin Calls & Broker Stop-Outs
Because you are trading with borrowed leverage, your broker will never allow you to lose their money. If a trade goes against you, the loss is deducted from your remaining "Free Margin".
If your losses continue and your account equity drops too low to cover your active Margin, the broker will issue a Margin Call (a warning). If it drops further to the broker's Stop-Out Level (usually 20% to 50% of required margin), the broker's algorithm will forcibly close your trades at a loss to protect themselves. This is the Forex equivalent of getting liquidated.
