Example setup
- Account currency: USD
- Balance: $1,000
- Risk: 1%
- Entry: 159.237
- Stop: 159.137
- Pip size: 0.01
The risk amount is $10. The stop distance is 10 pips because 159.237 minus 159.137 equals 0.10, and 0.10 divided by 0.01 equals 10.
What the calculator does
The calculator converts the USD/JPY pip value into the account currency and divides the risk amount by stop distance and pip value. That gives the lot size for the trade.
Lot size = $10 / (10 pips x USD pip value per 1.00 lot)
Take-profit by R:R
At 2.0 R:R, a 10 pip stop means a 20 pip target. If entry is 159.237 and the stop is below entry, the target price is 159.437.
