Direct answer
Pip value is the money change in your account caused by a one-pip move in a specific Forex instrument. To compare Forex with “currency exchange” pricing, first translate both into the same idea: a price change measured in the quote currency per unit of the base currency. Then convert that money change into your account currency using the relevant exchange rate and the position size assumptions.
Mechanism or definition
A pip is a standardized表示 of a small price move used in Forex. The pip size depends on the instrument’s quoting convention (commonly 0.0001 for many major pairs, and sometimes 0.01 for pairs quoted to two decimals). The pip value is not the pip itself; it is the value of one pip movement for your trade size.
A common general way to compute pip value uses three inputs:
- Pip size in price terms (for example, 0.0001 of the quote price).
- Contract size / position size (how many base units you control).
- Account conversion from the quote currency (or the currency you obtain from the pip move) into your account currency.
Step 1: Convert one pip price movement into “money per unit”
For a Forex pair quoted as Base/Quote, a one-pip move changes the price of base in terms of quote. If your pip size is \u0394P and your position is \u0394Base base units, then the corresponding change in quote-currency value is approximately:
- Quote-currency change per position \u2248 \u0394Base × \u0394P
This is the core mechanics: one pip is a price increment, and multiplying by controlled base units yields the quote-currency impact.
Step 2: Convert to account currency
If your account currency matches the quote currency from the calculation above, pip value is just that quote-currency change (after any needed contract scaling). If not, you must convert using an FX rate between your account currency and the quote currency used in Step 1.
A general conversion approach is:
- Pip value in account currency \u2248 (Pip value in quote currency) × (AccountCurrencyQuoteRate)
The “route” differs depending on which currency is your account currency and how the provider expresses conversion rates. Your independent check is to ensure you are using a rate direction consistent with the multiplication or division implied by the conversion.
Evidence or example (with stated assumptions)
Example A: Account currency equals quote currency
Assume:
- You trade a Base/Quote instrument.
- Pip size \u0394P is the smallest quoted increment for that instrument.
- Position size is \u0394Base base units.
- Your account currency is the Quote currency.
Then:
- Quote-currency pip value \u2248 \u0394Base × \u0394P
- Account-currency pip value is the same amount (no extra conversion step).
This explains why two accounts can see different numeric pip values while starting from the same one-pip price movement: the difference typically comes from the conversion step.
Example B: Account currency differs from quote currency
Assume the same pip size and position size as above, but your account currency is Account. Let \u0393 be the conversion factor that turns quote currency into account currency. Then:
- Pip value in account currency \u2248 (\u0394Base × \u0394P) × \u0393
In practice, \u0393 may be directly quoted (Account/Quote vs Quote/Account) and may require using the reciprocal. The failure mode is mixing up the rate direction, which flips the magnitude.
Comparing Forex vs “currency exchange”
A key material limitation is that currency exchange quotes are not standardized into pips. When a currency exchange platform quotes a rate, the “pip-like” concept only exists if you define:
- what smallest increment you care about (for example, one basis point, one cent move on a quoted price, or the smallest tick), and
- how that increment maps to a price change in base/quote terms.
Once you define the smallest increment, the mechanics become the same as Forex: multiply the corresponding price move by the relevant base amount and convert into account currency.
Limitations and risks (material failure modes)
- Pip size may differ by instrument: if your instrument is quoted with a different decimal convention, using the wrong pip size will produce a wrong pip value. 2. Rate direction errors: converting from quote to account currency can require division rather than multiplication. A direction mistake changes pip value by a factor. 3.
