What This Recipe Solves

Signal transitions are the moments that matter most, but they happen silently between checks. This script tracks state and fires an alert the instant a transition occurs.

for s in WATCHLIST:
    cur = requests.get(
        f"{API}/trades/get-current-action/{s}/aggressive",
        headers=H
    ).json()["action"]
    if last.get(s) and last[s] != cur:
