Description
Return 1/forwardQuote for expectedReverse and subtract it from positive reverseQuote for gap.
An exchange quote states how much of one currency corresponds to another. Reciprocals, price-level factors, valuation bridges, and pass-through models require consistent orientation.
Return 1/forwardQuote for expectedReverse and subtract it from positive reverseQuote for gap.
When to use this tool
Use Exchange Quote Reciprocal Gap when you need one supplied exchange-factor or valuation calculation.
How to use the tool and how it works
- Enter forwardQuote, reverseQuote. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read expectedReverse, gap. Use the output convention below.

| reverseQuote | Reverse Quote | Required. Finite number; strictly above 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| expectedReverse | Expected Reverse | Required. Finite number. |
| gap | Signed difference under the stated subtraction order. | Required. Finite number. |

}Limitations and assumptions
- This checks reciprocal quote consistency only; bid/ask spreads, fees, timestamps, and arbitrage feasibility are omitted.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Check currency direction, quote date, bid/ask conventions, and the full transaction or model before interpreting the result.
