How it's calculated.
Pip value per standard lot is the instrument's pip size multiplied by its contract size, converted into your account currency at the rate above and rounded to 2 decimals.
Position size is your amount at risk, divided by the pip value multiplied by your stop-loss distance in pips, then rounded down to the nearest 0.01 lot so a trade never risks more than you set.

Rounding up could push the trade past the risk amount you chose. Rounding down keeps the actual risk at or below your target.
