I need a dependable way to capture every alteration that occurs in a trading broker’s data feed and keep a clear audit trail of those changes. The broker has not been chosen yet—Interactive Brokers, TD Ameritrade, or E*TRADE are all on the table—so the solution must remain flexible enough to plug into any of their public APIs or downloadable reports. The fields I will most likely focus on are execution-related: timestamps, quoted prices, and volumes; however, I want the workflow to be able to monitor any additional columns that might prove useful later. In practical terms, I expect a repeatable script (Python, R, or another language you recommend) that can: • Connect to the selected broker’s API or data export • Take regular snapshots or pull historical records • Compare snapshots to highlight differences in an easy-to-read change log Please include brief documentation so I can install dependencies, schedule the job, and interpret the results without extra hand-holding. Clean code, clear comments, and a concise report of findings will determine acceptance.
