Alto FX

Compare an executed spot or forward FX transaction with the applicable historical market rate and calculate the estimated spread and monetary execution cost. Use when the user provides an executed FX rate and wants to understand how it compared with the market at the time. Each row requires exactly one of sell_amount or buy_amount. If calculation_status is executed_rate_better_than_market, the supplied executed rate is better than Alto's historical market benchmark for that trade direction. Alto does not calculate an execution cost in this case. Present the market rate and executed rate to the user and explain that the trade details may need reviewing if appropriate. Before calling this tool, ensure the information required for the requested analysis is available. If a missing input is material to the result and cannot be reliably derived from information already provided, ask the user for it rather than assuming it. If an input can reasonably be derived or a standard convention applied without materially changing the intended calculation, it may be inferred. For multiple trades, apply common information across rows where appropriate and ask once for missing information that applies to the whole batch.

analyse_executed_trades

Calculate an indicative current mark-to-market valuation of an existing FX forward contract using the current market forward rate for its value date. Use when the user supplies an existing forward contract and asks for its current indicative value or mark-to-market. Each row requires exactly one amount and a contract_rate. If a required input is missing and cannot be reliably derived from information already provided, ask the user for it rather than assuming it. Standard conventions may be used where reasonable and should be made clear when relevant. For batches, apply common information across rows where appropriate rather than repeatedly asking for the same input.

mark_to_market_forwards

Retrieve an indicative historical FX spot or forward market rate for a specified currency pair, historical date/time and value date. Use this tool when the user asks what an FX rate was at a particular point in the past. Results identify the standardized market base/quote pair used to quote the returned rate. This tool does not require an executed transaction, transaction amount or executed rate. If a required input is missing and cannot be reliably derived from information already provided, ask the user for it rather than assuming it. Standard conventions may be used where reasonable and should be made clear when relevant. For batches, apply common information across rows where appropriate rather than repeatedly asking for the same input.

get_historical_fx_rates

Retrieve indicative current FX spot or forward market rates for specified currencies, amounts and value dates. Use when the user asks for a current FX market rate, current spot rate or current forward rate. Rates are indicative market-data outputs and are not executable quotes. Each row requires exactly one amount. If a required input is missing and cannot be reliably derived from information already provided, ask the user for it rather than assuming it. Standard conventions may be used where reasonable and should be made clear when relevant. For batches, apply common information across rows where appropriate rather than repeatedly asking for the same input.
