shallowcom.currencyguard/guard-pricing · Verify this server
Analyze historic best/worst FX performance for a currency pair over a Guard's duration. Uses Bank of England historic rates. Returns a 'performances' array with 6 entries — BEST and WORST for each of three lookback periods (5, 10, 25 years). Each entry contains: type, lookbackYears, startDate/endDate, startRate/endRate, performancePercentage, startAmount, finalAmount, deltaAmount. For Guard-Pay: negative delta = cost decreased = BEST; positive delta = cost increased = WORST. For Guard-Receive: positive delta = receipt increased = BEST; negative delta = receipt decreased = WORST. Parameters must match the values used in the preceding price_guard call, including payReceive (PAY or RECEIVE).
