Pips, Pipettes and Lots: The Forex Trader's Guide

Forex measures price moves in pips, and how much a pip is worth depends entirely on your lot size. Get either of those wrong, confuse a pip with a pipette, or size a trade in the wrong lot, and you can risk ten times what you intended without noticing. This is the article that fixes both, permanently, so that before any trade you can answer the only question that matters: if this goes against me by my stop distance, exactly how many dollars do I lose?

What a pip actually is

A pip (“percentage in point”) is the standard small unit of movement in a currency pair. Its position depends on the pair:

• Most pairs (EUR/USD, GBP/USD, AUD/USD): a pip is the 4th decimal place. EUR/USD moving from 1.1000 to 1.1001 is one pip.
• Yen pairs (USD/JPY, EUR/JPY): a pip is the 2nd decimal place. USD/JPY moving from 150.00 to 150.01 is one pip.

To read a move, count at the pip place. EUR/USD 1.1000 → 1.1055 is 55 pips (0.0055 ÷ 0.0001). USD/JPY 150.00 → 150.85 is 85 pips (0.85 ÷ 0.01). Pips are the shared language of forex, everyone quotes stops, targets and spreads in them.

The pipette: the trap in the extra decimal

Here’s the mistake that catches nearly every beginner. Most modern brokers quote one extra decimal beyond the pip, a pipette, which is one-tenth of a pip.

• EUR/USD shown as 1.10005 → the final 5 is pipettes (5 pipettes = half a pip).
• A price of 1.10015 to 1.10025 is 1 pip (10 pipettes), not 10 pips.

The classic error: a beginner sees the price tick through “10” on the last digit and thinks the market moved 10 pips, when it moved 1 pip (10 pipettes). Or they set a stop of “50” in a field measured in pipettes, thinking it’s 50 pips, and get stopped out five times tighter than intended. Whenever you set a stop or read a move, know whether you’re counting pips or pipettes. The pip is the 4th decimal (2nd on yen pairs); anything past that is a fraction of a pip.

Lots: what makes a pip worth money

A pip on its own is just a distance. Its dollar value depends on how big your position is, and position size in forex is measured in lots. There are four standard sizes:

Each step down is one-tenth the size, and one-tenth the pip value. This is forex’s equivalent of the futures full/mini/micro contract ladder: the same market, scaled to fit your account. (If you also look at futures, that parallel is spelled out on the bridge, see Lots vs Contracts.)

Note the ”~”, for pairs where the US dollar is the quote currency (the second one, as in EUR/USD), pip value is essentially fixed at those round numbers. For other pairs it floats slightly with the exchange rate, but your platform calculates the exact figure for you. The lot-size logic never changes.

What a stop actually costs, in dollars

Put pips and lots together and every trade resolves to one line. Take the same 30-pip stop on each lot size:

• 1 standard lot: 30 pips × $10 = $300 at risk
• 1 mini lot: 30 pips × $1 = $30 at risk
• 1 micro lot: 30 pips × $0.10 = $3 at risk

Same stop, same pair, same chart, a hundred-fold spread in risk between a standard lot and a micro. This is why the lot you choose matters more than almost any other single decision, and why beginners should trade micro lots: you make the same decisions and the same mistakes for a fraction of the cost.

The formula, worth committing to memory:

Risk per trade = lots × stop distance in pips × pip value

The only position-sizing method you need

Most beginners pick a lot size based on how much they want to make. That’s backwards. Size from what you’re prepared to lose:

1. Set your risk, a common rule is 1–2% of the account per trade. On a $2,000 account at 1%, that’s $20.
2. Measure your stop in pips, say 40 pips.
3. Risk per pip = $20 ÷ 40 = $0.50 per pip.
4. Convert to lots, at $0.10 per pip per micro lot, $0.50 ÷ $0.10 = 5 micro lots.

That turns every trade from a guess into a controlled decision. A dedicated forex position-size tool is on the way; in the meantime the method above is all you need. (We cover it in depth in [Position Sizing for Forex →].)

The three mistakes to never make

The research on how beginners blow up keeps surfacing the same three errors, avoid these and you’re ahead of most:

1. Counting pipettes as pips, thinking a 5-pipette move is 5 pips. Know your decimal places.
2. Using the same lot size across different pairs, pip value differs between pairs (especially yen pairs), so identical lots mean different real risk. Size each trade to dollars risked, not lots.
3. Skipping the currency conversion when your account isn’t in USD, the pip value in your account currency is what matters; let your platform compute it.

Quick reference

• Pip, the standard small unit; 4th decimal on most pairs, 2nd on yen pairs.
• Pipette, one-tenth of a pip; the extra decimal most brokers show. Don’t mistake it for a pip.
• Lot, position size: standard (100k), mini (10k), micro (1k), nano (100 units).
• Pip value, dollars per pip; ~$10 / $1 / $0.10 / $0.01 per lot size on USD-quoted pairs.
• Risk per trade, lots × stop in pips × pip value. Compute it before every trade.

Test yourself

1. EUR/USD moves from 1.1000 to 1.1042 in your favour on 1 mini lot. How many pips, and what did you make? (42 pips; 42 × $1 = $42.)
2. Your broker shows GBP/USD as 1.27505 and it moves to 1.27515. How many pips? (1 pip, the change is 10 pipettes. The 5th decimal is pipettes.)
3. You’ll risk $30 on a 60-pip stop. What pip value do you need, and how many micro lots is that? ($0.50 per pip; at $0.10 per micro lot, that’s 5 micro lots.)
