Preview Execution monitoring

We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

Fetch recent insider transactions from Yahoo Finance (SEC Form 4 data).

Instructions

> Note: If uv is not installed or pyproject.toml is not found, replace uv run python with python in all commands below.

uv run python scripts/insider_trading.py SYMBOLS [--days DAYS]

Arguments

  • SYMBOLS - Single ticker or comma-separated list (e.g., NVDA or NVDA,PLTR,GOOG)
  • --days - Trailing days to look back (default: 90)

Output

Returns JSON with:

  • transactions - List of insider trades with insider name, role, transaction type, shares, price, value, date, ownership type
  • summary - Net sentiment (net_buying, net_selling, neutral), buy/sell counts and values

For multiple symbols, results are ranked by net buying value (most buying first).

Use Cases

  • "Show me insider buys for NVDA in the last 90 days"
  • "Compare insider activity across NVDA, PLTR, GOOG"
  • "Which of these stocks has the most insider selling recently?"

Dependencies
