Pips, Lots and Signal Math: Turning a Forex Signal Into Dollar Risk

A pip is the standard unit of price movement in a currency pair (0.0001 for most pairs, 0.01 for pairs quoted in Japanese yen), and a lot is the standard unit of trade size (100,000 units of the base currency for a standard lot). Multiply the pip size by the number of units and you get the value of one pip; multiply that by the stop-loss distance and you get what a signal actually risks in your account.

In short: dollar risk = stop distance in pips x pip value per lot x number of lots. On any pair quoted in US dollars (EUR/USD, GBP/USD, AUD/USD), one pip on a standard lot is worth $10, on a mini lot $1, and on a micro lot $0.10. On pairs where the dollar is the base (USD/JPY, USD/CAD, USD/CHF), the pip value depends on the exchange rate. To size a position, divide the dollars you are willing to lose by (stop pips x pip value per lot).

Why this is the most important page on the site

Signal marketing talks in pips: “+450 pips this month.” Pips are a convenient unit because they hide the thing that matters, which is money. Four hundred and fifty pips is $45 on a micro lot and $4,500 on a standard lot. And a provider’s “+450” can be made up of large wins on small positions and large losses on large ones. Until you convert pips to dollars at your own size, a signal’s numbers are not yet about you.

Pips

A pip (originally “percentage in point”) is the conventional smallest standard price increment:

Most pairs: the fourth decimal place, 0.0001. EUR/USD moving from 1.0850 to 1.0851 is one pip.
Yen pairs: the second decimal place, 0.01. USD/JPY moving from 150.00 to 150.01 is one pip.

Most platforms now quote one extra digit, a pipette or fractional pip: 1.08505 on EUR/USD, 150.005 on USD/JPY. A spread shown as “12 points” on a five-digit quote is 1.2 pips. Confusing points with pips is one of the easiest ways to misread a signal by a factor of ten.

Lots

A lot is a standard trade size, measured in units of the base currency (the first currency in the pair).

Name	Lots	Units of base currency
Standard	1.00	100,000
Mini	0.10	10,000
Micro	0.01	1,000

Buying 0.25 lot of EUR/USD means buying 25,000 euros against dollars. Many platforms allow any size in steps of 0.01 lot; some brokers also offer nano lots or let you specify units directly.

Pip value, pair by pair

The value of one pip is always pip size x units, expressed in the quote currency (the second currency). If the quote currency isn’t your account currency, you convert.

Case 1: the dollar is the quote currency (EUR/USD, GBP/USD, AUD/USD, NZD/USD)

0.0001 x 100,000 = 10 US dollars per pip per standard lot, regardless of the exchange rate.

Case 2: the dollar is the base currency (USD/JPY, USD/CAD, USD/CHF)

The pip value comes out in the quote currency, so divide by the exchange rate to get dollars.

USD/JPY at an illustrative 150.00: 0.01 x 100,000 = 1,000 yen; 1,000 / 150 = $6.67 per standard lot.
USD/CAD at an illustrative 1.3700: 0.0001 x 100,000 = 10 Canadian dollars; 10 / 1.37 = $7.30.
USD/CHF at an illustrative 0.8800: 10 Swiss francs / 0.88 = $11.36.

Case 3: crosses (no dollar in the pair, such as EUR/JPY or EUR/GBP)

Work out the pip value in the quote currency, then convert at the relevant dollar rate. EUR/JPY: 1,000 yen per standard lot, converted at USD/JPY 150.00 = $6.67.

All values below were computed at illustrative rates, not live prices. Rates move, so pip values on non-USD-quoted pairs move with them.

Pair (illustrative rate)	Standard lot	Mini lot	Micro lot
EUR/USD (1.0850)	$10.00	$1.00	$0.10
GBP/USD (1.2700)	$10.00	$1.00	$0.10
AUD/USD (0.6600)	$10.00	$1.00	$0.10
USD/JPY (150.00)	$6.67	$0.67	$0.07
USD/CAD (1.3700)	$7.30	$0.73	$0.07
USD/CHF (0.8800)	$11.36	$1.14	$0.11
EUR/JPY (USD/JPY at 150.00)	$6.67	$0.67	$0.07

If your account is in Canadian dollars

Convert the US-dollar pip value into Canadian dollars. At USD/CAD 1.3700, a pip on one standard lot of EUR/USD is $10 US x 1.37 = C$13.70. On USD/CAD itself the pip value is simply C$10 per standard lot, because the Canadian dollar is the quote currency.

Converting a signal into dollar risk

Take a signal: SELL EUR/USD, entry 1.0850, stop 1.0880, take profit 1.0790.

Stop distance: 1.0880 minus 1.0850 = 30 pips.
Pip value: $10 per standard lot.
Dollar risk per standard lot: 30 x $10 = $300.

At 0.10 lot, the risk is $30. At 2 lots, $600. The signal is the same; your exposure isn’t.

Working backwards: position sizing

The more useful direction is the reverse. Decide what you are prepared to lose, then size the trade to fit the signal’s stop.

Position size (lots) = dollars at risk / (stop pips x pip value per standard lot)

Example A: EUR/USD. A $5,000 account risking 1% per trade can lose $50. With a 30-pip stop:

$50 / (30 x $10) = 0.1667 lot. Platforms trade in 0.01 steps, so round down to 0.16 lot. Actual risk: 30 x $1.60 = $48.

Example B: USD/JPY. Same $50 budget, a signal with a 40-pip stop, USD/JPY at 150.00 (pip value $6.67 per standard lot):

$50 / (40 x $6.67) = 0.1875 lot, rounded down to 0.18 lot. Actual risk: 40 x 0.18 x $6.67 = $48.

Always round down. Rounding up quietly raises your risk on every trade. Approaches beyond a fixed percentage, including the Kelly criterion and why it is dangerous at full size, are covered in position sizing and the Kelly criterion.

Margin is not risk

Margin is the deposit your broker holds while a trade is open. It is not the amount you can lose.

The 0.16 lot of EUR/USD in Example A controls 16,000 euros, worth 16,000 x 1.0850 = $17,360.

United States: CFTC rules require a minimum security deposit of 2% of the notional value for major currency pairs and 5% for others, which caps leverage at 50:1 and 20:1. On this trade the minimum is 2% x $17,360 = $347.20.
EU and UK: under rules that ESMA introduced in 2018 and national regulators (including the FCA) made permanent, retail leverage on major pairs is capped at 30:1 as of November 2026. The minimum margin would be $17,360 / 30 = about $578.67.
Canada: margin for retail forex at CIRO-regulated dealers is set by CIRO rules and varies by currency. See forex regulation in Canada.

The position’s notional value is about 3.5 times the $5,000 account. That is the effective leverage of the trade, and it is a better measure of exposure than the margin figure. A 1% move in EUR/USD (about 108 pips) on this position is about $174, or 3.5% of the account. How margin calls and stop-outs work is explained in leverage and margin in forex.

Pips in a track record

Now apply this to a provider’s claims. “This month: +450 pips” could mean:

15 trades, 10 winners of 60 pips and 5 losers of 30 pips: +600 minus 150 = +450 pips. At a constant size, that is profitable.
The same pips at varying sizes: if the 10 winners were traded at 0.10 lot and the 5 losers at 1.00 lot, the result in dollars is (600 x $1) minus (150 x $10) = minus $900.

Pip totals can’t be compared between providers who size differently, and they ignore spreads, commissions and swaps. Ask for results in percentage return on a verified account. The broader method is in how to verify a signal track record.

What can go wrong

Points mistaken for pips. A “50-point stop” on a five-digit quote is 5 pips. Misread, you size ten times too large.
Yen pairs treated like dollar pairs. Assuming $10 per pip on USD/JPY over-states the pip value by half and under-sizes the position; the reverse mistake on USD/CHF does the opposite.
Pip values drift. On USD-based and cross pairs, pip value changes as rates change. Recalculate for each trade.
Rounding up. Small per trade, but it compounds across hundreds of signals.
Stops that don’t hold. Your sizing assumes the stop fills at its price. Gaps and slippage can turn a $48 risk into much more.

The short version

Pip value = pip size x units, in the quote currency, converted to your account currency. For USD-quoted pairs that is $10 per standard lot. To size a signal, divide your dollar risk by (stop pips x pip value per lot) and round down. Margin is the deposit, not the risk, and pip totals in marketing tell you nothing until they are converted to money at a consistent size.
