How many lots can I trade so a stopped-out trade loses exactly what I planned?

Result

Position size

5.00 lots

Risk per trade
$1,000.00

A stopped-out trade at this size loses exactly the risk above, before spread and commission.

Not investment advice

$10 for a standard lot of EUR/USD.

How it's worked out

Lots = (account × risk per trade) ÷ (stop in pips × pip value per lot)

With your numbers: ($100,000 × 1%) ÷ (20 pips × $10.00) = 5.00 lots

How it works

Lots equal your account times the share of it you risk on one trade, divided by the stop distance in pips times the pip value of one lot. Nothing else enters the figure.

The pip value starts at $10, a standard lot of EUR/USD. For gold, indices or crosses, work out the real pip value in the pip value calculator and carry it over.

Questions

Why size from the stop instead of a fixed lot count?

A fixed lot count makes the loss depend on wherever the stop happens to sit. Sizing from the stop turns every trade into the same planned loss, which is what a firm's daily limit actually prices.

What risk per trade do funded traders use?

Often between 0.25% and 1% of the account, because a 5% daily limit survives only a handful of ordinary losses at 1%. The calculator shows the dollar risk so you can check it against your own limits.

Does this include spread and commission?

No. It prices the distance to your stop. What entering and leaving a trade costs on top is on the live board and in the cost of a trade on the calculators page.
