Quote-checking protocol · TXT

This fixed EUR/USD example uses 9 February 2027 as an assumed common value date. It is separate from the form, is not a live quote and remains available without JavaScript.

1. Identify BASE/QUOTE and the rate unit. EUR/USD means USD per one EUR. Record the provider and observation time separately; the calculator has no quote feed.

2. Obtain the two spot sides, the two directly signed adjustments, their explicit point size and one common future value date. If the source only gives 15/12, ask for its signs, side mapping and scale. Do not infer them from the size order.

3. Use the fictional reference: EUR/USD, assumed value date 2027-02-09, spot 1.10000/1.10020, points −15/−12, point size 0.0001 USD per EUR per point. Enter quantity 100000 EUR if an amount check is wanted.

4. Convert points into rate adjustments: −15 × 0.0001 = −0.00150; −12 × 0.0001 = −0.00120. Then add each to the matching spot side: Bid 1.09850, Ask 1.09900. Do not round between these steps.

5. Check positive rates and Bid ≤ Ask. Forward spread = 1.09900 − 1.09850 = 0.00050 USD per EUR = 5 declared points. Reverse (forward − spot) / 0.0001 on each side to recover −15 and −12.

6. For 100000 EUR, selling base at bank Bid gives 109850 USD; buying base at bank Ask requires 109900 USD. These are alternative transaction amounts, not profits or a separate 50 USD fee.

7. Check a positive example: spot 1.10000/1.10020, points +20/+23, scale 0.0001 → forward 1.10200/1.10250. The forward spread is again 5 declared points.

8. Check valid narrowing: spot 1.1000/1.1004, points +3/+1, scale 0.0001 → forward 1.1003/1.1005. Points Bid > points Ask is allowed here because the outright remains ordered. A crossed outright must be investigated, not sorted.

9. Preserve the source convention, exact inputs, common value date and calculation export. Verify any separate charges, settlement rounding and calendar terms with the provider; this arithmetic check does not validate those terms.

10. Stop if signs, units, matching dates or sides are unresolved. Forward points do not forecast future spot. This protocol does not calculate a fair forward curve, overnight retail swaps, profit, margin or suitability.
