Position size calculator
Lot size and pip value for 17 markets — 15 currency pairs, gold and bitcoin. What it has that a broker's calculator does not is the field most of them leave blank: how far away to put the stop, suggested from what each market has actually been doing rather than from a round number.
Where the suggested stop comes from
Two measurements, both published on this site and both refreshed with it. ATR is the average hourly bar for that market, which is the ruler every number in the marker studies is quoted in — a stop under one ATR is inside the noise of a single hour. ADR is the median day of 2025 — the middle day, not the mean, which the daily-range page publishes beside it and which runs 8–16% higher because a handful of violent days drag it up. The middle day is the honest scale for a stop meant to survive a session.
Neither is a recommendation. They are the distances the market has actually been covering, offered so that the number in the box is anchored to something instead of to a habit. Prices and the hourly ATR are as of 21 Aug 2026 19:00 UTC, and are the same figures the levels pages price their distances in; the daily ranges come from the 2025 table.
The arithmetic, so you can check it
Position size is one division and one currency conversion, and it is written out here because a calculator that will not show its working is a calculator you have to trust.
risk = account × risk% stop price = stop distance × 0.0001 on most pairs, 0.01 on the yen crosses, 1.00 on gold and bitcoin per unit = stop price × (quote currency → account currency) units = risk ÷ per unit lots = units ÷ contract size
Contract size is a broker convention, not a fact about the market, which is why it is a field you can edit rather than a constant. A standard forex lot is 100,000 units of the base currency almost everywhere; gold and bitcoin are where houses differ, and the defaults here (100 ounces, 1 coin) are the common ones rather than the universal ones. Check yours before sizing anything real.
The conversion rates come from our own feed, as of 27 Aug 2026 14:30 UTC, not from a live rate service. For sizing a position that is accurate enough — a day-old rate moves pip value by well under a percent — but it is not a currency converter and should not be used as one.
Pip value, on its own
The calculator shows it for whatever you have selected, because it is the quantity everything else is built from: one pip, one contract, in the currency the account is denominated in. For the currency pairs a pip is the fourth decimal place, or the second on the yen crosses; for gold and bitcoin there is no pip and the unit is one dollar of price.
Where those measured distances come from: what each market does hour by hour, its average daily range by year, and how often price reaches a level once it is set.
Chart analytics, not investment advice. Nothing here is a recommendation to take a position, and the sizes it prints are arithmetic on the numbers you typed.
