Sizing and risk
Forex Pips, Lots and Position Size Explained
How pips connect to lot size, stop distance and the money placed at risk.
Answer first
What you should remember
- A pip measures movement, not a fixed cash amount.
- Pip value changes with the pair, position size and account currency.
- Position size comes from risk and stop distance, not balance alone.
What is a pip?
For most pairs a pip is 0.0001, while JPY pairs commonly use 0.01. The extra digit shown by many platforms is a fractional pip, not a full pip.
What is a lot?
A standard lot typically represents 100,000 base-currency units, a mini lot 10,000 and a micro lot 1,000. Notional value is not the cash paid under margin, but it reveals the true exposure.
Position-size formula
Calculate acceptable cash loss, then divide it by stop distance in pips multiplied by pip value per size unit. A wider stop requires a smaller position to keep risk unchanged.
Common sizing errors
Common errors include using one lot size for every pair, ignoring pip-value differences, rounding size upward and opening correlated positions that exceed total risk.

Is pip value fixed?
No. It depends on the pair, size, exchange rate and account currency.
Is a larger lot better?
No. The right size keeps planned risk at a level the account can absorb.
