Pip value drifts when the quote currency is not the account currency

[Amanhasnoname]

On a USD account, EURUSD is simple: roughly $10 per pip per standard lot, always. Cross and JPY pairs are different, because pip value is converted at whatever the rate is at the time.

USDJPY example. A pip on 1 lot is 1,000 yen. At 140 that is about $7.14. At 160 it is $6.25. Same lot size, same 5 pip stop, and risk differs by roughly 12 percent depending on the level of the pair. On a EUR or GBP account, even EURUSD has a conversion step, so every dollar of P&L moves with the EURUSD rate or the account currency pair.

Why this matters for scalps: profit per trade is small, often a few dollars. Brokers convert at their own rate, sometimes with a markup. If the markup is 0.5 percent on a $4 profit, that is 2 cents, trivial once but not across thousands of trades. Rounding to whole cents on tiny positions adds noise too.

Things to check:

- Pip value used by the sizing calculator, and whether it updates with price.
- Conversion rate on the statement against the market rate at close.
- Whether the account currency should be the one that matches the main pair traded.

Has anyone compared statement conversions against actual market rates, and how large was the difference?
