What is a pip?

The smallest unit of price movement — and why it matters for sizing.

TL;DR

A pip is the smallest standardised price move in a forex pair — usually the 4th decimal place (0.0001) for most pairs, or the 2nd decimal place (0.01) for JPY pairs. It's how forex traders quote moves and size risk.

How pips work

If EUR/USD moves from 1.0850 to 1.0851, that's a 1-pip move. If GBP/JPY moves from 198.45 to 198.46, that's also a 1-pip move (JPY pairs use the 2nd decimal because the yen is denominated in much smaller units).

Pipettes — the fractional pip

Most modern brokers quote 5 decimals (or 3 for JPY). The 5th decimal is called a pipette — 1/10th of a pip. So EUR/USD at 1.08504 vs 1.08505 is a 1-pipette move.

Pip value scales with lot size

The dollar value of a pip depends on lot size and the pair's quote currency.

→Standard lot (100,000 units): ~$10 per pip on USD-quoted pairs
→Mini lot (10,000 units): ~$1 per pip
→Micro lot (1,000 units): ~$0.10 per pip
→For pairs where USD is the base (USD/JPY), divide by the current rate

Worked example

Sizing a GBP/USD trade with the 1% rule

You have a $10,000 account, want to risk 1% per trade, with a 30-pip stop on GBP/USD.

1Account size$10,000
2Risk per trade (1%)$100
3Stop distance30 pips
4Max pip value$100 ÷ 30 = $3.33 per pip
5Lot size$3.33 × 10,000 (since standard lot = $10/pip) = ~33,000 units

Takeaway

Position size should always follow from your stop distance and risk per trade — never the other way around.

Common mistakes

What to avoid

!Treating pips and pipettes as interchangeable when reading quotes
!Sizing positions in lots before knowing your stop — risk becomes whatever the market does
!Forgetting that JPY pairs use the 2nd decimal, not the 4th — easy to miscount by 100x
!Ignoring spread cost in pip terms — paying 2 pips on entry doubles a 1-pip target's required move
