US30 lot size calculator
The Dow moves hundreds of points in a day, which makes the size of the position matter more than the entry.
Value per point is what one lot of US30 gains or loses when the index moves one point. It is 1 dollar at many brokers and 10 or 20 at others, and it is the one number to check in your platform's specification before sizing.
Free, and nothing is stored. Check every figure against your own platform before you trade on it. Nothing here is advice, and trading carries risk.
US30 is the name most platforms give a contract on the Dow Jones Industrial Average, the index of 30 large US companies. It is priced in points and settled in US dollars.
The arithmetic: loss per lot if stopped = stop distance in points × value per point per lot. Lot size = the amount you are prepared to lose ÷ loss per lot.
Worked through: a $10,000 account risking 1% is $100. A stop 50 points away, where one lot is worth $1 a point, loses $50 per lot, so the position is 2 lots. If your broker's contract is $10 a point, the same trade is 0.2 lots. That factor of ten is why value per point is a field here and not an assumption.
If your account is in pounds or euros, choose it above and enter your platform's rate. The index is priced in dollars, so the risk is converted into dollars before sizing.
For retail clients of FCA-authorised firms, leverage on major indices such as the Dow is capped at 20:1. That limits the largest position you can open. It does not change the size that keeps your risk where you set it.
