How this service works
QuantOracle: fx/carry-trade
Output
Returns a JSON object with: P&L in dollar amount, spot return percentage, carry return percentage, total return percentage, levered return percentage, annualized total return, and the breakeven depreciation percentage — decomposing exactly how much of the trade's performance came from spot movement vs the interest rate differential.
Example use cases
Example prompt
“I entered a EUR/USD carry trade at 1.25 and plan to exit at 1.26 with a $50,000 notional and 2x leverage held for 30 days — the borrow rate is 2% and the invest rate is 5%. Can you break down the spot return, carry return, total return, levered return, annualized return, and the breakeven depreciation for me?”
Technical details
Endpoint
POSThttps://api.quantoracle.dev/v1/fx/carry-tradeWhen to prefer
Use this endpoint when you need a full decomposition of an FX carry trade's return profile — separating spot and carry contributions, computing leverage effect, and annualizing returns — rather than a simple spot FX gain/loss calculator. Ideal for quantitative traders, portfolio analysts, or AI agents modeling currency strategies with interest rate differentials.
Side effects
- Missing required fields (leverage, notional, spot_entry, spot_exit, holding_period_days, borrow/invest rates) returns validation error
- Leverage or notional of zero or negative may cause division errors or unexpected results
- Invalid rate values (e.g. rates > 1 if interpreted as decimals vs percent) may yield nonsensical annualized returns
- Network timeout or service unavailability returns 5xx
- Insufficient USDC balance for x402 payment results in 402 Payment Required
