Top Options Contracts Query

Given a table of order executions, write a query to find the top 5 most traded options contracts per day, partitioned by underlying asset.

Treat traded volume as the sum of quantity. A contract is identified by contract_symbol, and the trading day comes from executed_at.

Output

1. One row per included trading day, underlying asset, and option contract.
2. Columns: trade_date, underlying_asset, contract_symbol, total_quantity, and contract_rank.
3. Include the five highest-volume contracts per day and underlying asset, order by date, underlying asset, rank, and contract symbol for ties.
