# Big-Trade Alerts

> Follow the live tape and print every fill over $10,000, with the trader's name.

Follow [the live tape](/streams/live-tape) and print every fill over \$10,000. Remember the fills you have printed: a reorged block can arrive twice.

```python Python theme={null}
import json, os, requests

seen = set()
with requests.get(
    "https://codex-api.nomos.trade/v1/stream/fills",
    headers={"Authorization": f"Bearer {os.environ['CODEX_KEY']}"},
    stream=True, timeout=(10, 60),
) as r:
    for line in r.iter_lines(decode_unicode=True):
        if not line.startswith("data: "):
            continue
        block = json.loads(line[6:])
        for f in block["fills"]:
            key = (f["tx"], f["logIndex"])
            if key in seen or f["usd"] < 10_000:
                continue
            seen.add(key)
            who = (f.get("profile") or {}).get("name") or f["wallet"]
            print(f"{who} {f['side']} ${f['usd']:,.0f} at {f['price']:.3f} in {f['conditionId']}")
```

<Note>
  The stream drops when your connection does. Reconnect in a loop, and keep `seen` bounded (for example, the last 100,000 keys) in a long-running process.
