BTCUSD Lot Size Calculator
On a $10,000.00 account, risking 2% ($200.00) with a stop of 20 points, BTCUSD sizes to 10.00 lots. One point on 1.00 lot is $1.00. The loss at that rounded size is $200.00, with no spread and no commission.
BTCUSD assumes 1 bitcoin per lot. 1 point = 1. One point on 1.00 lot is $1.00. A platform with a smaller coin size per lot needs a different lot for the same cash risk. The minimum here is 0.01. A stop of 20 points on 1.00 lot is $20.00, which is why the worked example comes out at 10.00 lots. The grid uses 100, 250, 500 point stops. Match the contract size or the cash risk is wrong by that factor.
BTCUSD contract: 1 BTC per 1.00 lot. This size is an assumption and differs by platform. 1 point = 1. A 0.01 lot is $0.01 per point, a 0.10 lot is $0.10, and 1.00 lot is $1.00. The quote currency is USD, so the 2026-10-15 bundled rates are not applied. Minimum lot 0.01, step 0.01. The lot rounds down, so the loss at the stop stays at or under the risk when spread and commission are left at zero.
The risk table for BTCUSD uses stops of 100, 250, 500 points. On $10,000.00 at 2% those three stops size 2.00 lots, $200.00 at the stop; 0.80 lots, $200.00 at the stop; 0.40 lots, $200.00 at the stop.
