Interview Prompt
The market-data team dumps end-of-day OHLCV bars as CSV, one row per ticker per trading day (Date,Ticker,Open,High,Low,Close,Volume). A trader wants a quick volatility snapshot for one symbol: the day it had the widest intraday swing (High minus Low, earliest Date on ties) and its average daily Volume over the dump. Return an empty dict if the symbol never traded.
Summary
Prices move. One stretch had the widest gap.
