How this service works
QuantOracle: risk/transaction-cost
Output
Returns a detailed cost breakdown including: total cost in basis points, spread cost in USD, market impact in USD, commission in USD, total cost in USD, cost as a percentage of trade value, round-trip cost in bps and USD, breakeven move percentage, and computation latency in milliseconds.
Example use cases
Example prompt
“What are the full transaction costs for buying 10,000 shares of a stock with a $500,000 trade value, ADV of $10 million, spread of 5 bps, market impact of 8 bps, commission of 0.02%, and a participation rate of 20%?”
Technical details
Endpoint
POSThttps://api.quantoracle.dev/v1/risk/transaction-costWhen to prefer
Use this endpoint when you need a full decomposition of transaction costs for a single equity trade — specifically when you need spread cost, market impact, commission, and round-trip cost all broken down with a breakeven move calculation. Prefer this over generic slippage estimators when you have ADV, participation rate, and spread data available and need precise bps-level cost attribution.
Side effects
- Missing required fields (adv, shares, trade_value) returns validation error
- Negative or zero values for share count or trade value may return computation error
- Participation rate outside 0-1 range may return invalid input error
- Commission percentage expressed as decimal vs percentage may yield unexpected results
