US30 lot size calculator

US30 — also DJ30 or WS30 — is a CFD on the Dow Jones Industrial Average. The index is above 40 000 points and often moves 300–500 points a day, so stops are measured in tens or hundreds of points.

With $1 per point per lot, a 100-point stop on one lot risks $100. Brokers set the value per point differently, which changes the lot size tenfold for the same risk, so set the contract size before trusting any number.

Contract size: check yours for US30

One US30 lot is $1 per point at many brokers; $5 or $10 at others. Set yours from the contract specification.

In MetaTrader, right-click US30 in Market Watch → Specification: “Contract size” is the number to put in the calculator. The formula is the same for every instrument: lots = risk ÷ (stop distance × contract size × quote-to-account rate).

Did your US30 trades risk what you planned?

A calculator sizes the next trade. The journal checks the last hundred: it reads every MT4/MT5 US30 trade, shows the real R of each from its stop, and with a max-loss-per-trade rule marks the trades that lost more than you allowed. Free for one account.
