Direct answer
Pip value is the monetary value of one pip move for a specific instrument and trade size. A Currency Strength Meter (which aggregates currency moves) may need pip value to translate those moves into amounts that are comparable in your account currency. Because every provider can define “pip” slightly differently (e.g., spot FX vs a derivative wrapper), the pip value calculation always starts with explicit assumptions about pip size and contract specifications, then converts the result into the account currency.
Mechanism and definition
A “pip” is a standardized price increment. In many major FX pairs quoted to 5 decimals, one pip is often treated as 0.00010 (i.e., the change in the 4th decimal place). In pairs quoted to fewer decimals, a pip may correspond to a different decimal step. The important part for calculation is: pip size (the numeric price change that equals one pip).
To compute pip value for a given trade, separate three steps:
- Convert pip size into a price move
- Let ΔP be the pip price movement for the instrument.
- For a typical spot FX quote, ΔP equals the one-pip change in the quoted price.
- Translate price move into quote-currency money
- Let L be the position size in base currency units (for spot-like contracts this is commonly notional).
- A common mechanics form is: value in quote currency for 1 pip = L × ΔP.
- This is a conceptual model: the exact factor can differ if the platform uses a different contract multiplier or defines L differently.
- Convert to account currency
- Let rate(AccountCcy per QuoteCcy) be the conversion rate needed to express the quote-currency amount in your account currency.
- Then: pip value in account currency = (L × ΔP) × FX conversion rate.
When the account currency is neither side of the quoted pair
If your account currency is not the instrument’s quote currency, you convert in one or more hops using the available market rates you assume for that calculation. The conversion path (direct quote vs cross rates) matters because rounding and quote direction (multiply vs divide) can change the numeric result.
Evidence by example (with explicit assumptions)
Assume a simplified spot-style FX instrument with these fixed definitions:
- Pip size: ΔP = 0.00010
- Position size: L = 100,000 units of the base currency
- The instrument quote is “Base/Quote” (meaning the market price is Quote per Base)
Step 1–2 (money in quote currency):
- Quote-currency value per pip = L × ΔP
- = 100,000 × 0.00010
- = 10.00 in the quote currency
Step 3 (convert to account currency):
- If account currency equals the quote currency, pip value is 10.00.
- If account currency differs, you apply the assumed conversion rate.
- Example logic: if the account currency is “Acc” and you need “Acc per Quote”, multiply the 10.00 by that assumed rate.
- If you instead have “Quote per Acc”, you divide. The key check is dimensional consistency: the conversion must cancel the quote-currency unit and leave account-currency units.
For Currency Strength Meter calculations, the same pip-value conversion can be used to express currency strength contributions in a common unit (account currency), enabling aggregation across currencies.
Limitations, failure modes, and verification
At least four material limitations can break pip value comparisons:
- Instrument wrapper differences
- CFDs, futures, or other derivatives can use different contract multipliers, tick sizes, or pip conventions than spot FX.
- If you reuse a spot-style formula without matching the wrapper’s specification, the pip value will be wrong.
- Pip definition and decimal precision
- Pip size depends on how the instrument is quoted (number of decimals) and how the provider defines “pip” for that instrument.
- Account-currency conversion uses assumptions
- Conversion rates move; a Currency Strength Meter that updates with live prices effectively uses dynamic conversion.
- Even without live data, your calculation must clearly state the assumed conversion rate(s) for the moment you evaluate.
- Rounding and quote direction errors
- Many mistakes come from using the wrong direction of a conversion rate (multiply vs divide) or rounding intermediate steps differently.
Independent verification method
To verify any pip value number you see:
- Confirm the instrument’s pip size (ΔP) and the platform’s position size definition (how L maps to notional).
