AUDUSD is a forex major quoted in USD. BlackBull's English contract specifications list it at 100,000 units, a 0.01 minimum trade and a 0.00001 point (https://blackbull.com/en/support/contract-specifications/). This calculator uses that 100,000 unit contract and a pip of 0.0001, so 1.00 lot is $10.00 per pip, the same dollar pip as EURUSD and GBPUSD. The lot matches those pairs only when the stop and the risk match. This grid uses 14, 28, 56 pip stops, not the 10, 20 and 40 on the EURUSD page. Leverage changes the margin held on the position. It does not change this lot.
AUDUSD contract: 100,000 units per 1.00 lot. 1 pip = 0.0001. A 0.01 lot is $0.10 per pip, a 0.10 lot is $1.00, and 1.00 lot is $10.00. 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 AUDUSD uses stops of 14, 28, 56 pips. On $10,000.00 at 2% those three stops size 1.42 lots, $198.80 at the stop; 0.71 lots, $198.80 at the stop; 0.35 lots, $196.00 at the stop.
