Core Forex Calculations Explained

1. Pip Value

A pip is the smallest price move in most currency pairs, usually 0.0001.

Formula (for standard lot of 100,000 units):
Pip Value = (0.0001 ÷ Exchange Rate) × Lot Size

Example: EUR/USD at 1.1000
Pip Value = (0.0001 ÷ 1.1000) × 100,000 = $9.09 per pip

2. Position Size

Position size determines how many lots you trade based on your account size and risk tolerance.

Formula:
Position Size = (Account Risk × Account Balance) ÷ (Stop Loss × Pip Value)

Example:
Risk = 2%, Account = $5,000, Stop Loss = 30 pips, Pip Value = $1
Position Size = (0.02 × 5000) ÷ (30 × 1) = 3.33 micro lots

3. Profit and Loss

Profit = Number of Pips × Pip Value × Lot Size

Example:
Trade wins 50 pips, 1 mini lot (10,000 units), pip value = $1
Profit = 50 × $1 = $50

4. Leverage and Margin

Used Margin = (Lot Size × Contract Size) ÷ Leverage

Example:
1 standard lot = 100,000 units, Leverage = 1:100
Used Margin = 100,000 ÷ 100 = $1,000
