What the key opens
Three live reads inside the Coil MCP server, answered the same day instead of a market day late:
- Market regime: the stock market’s verdict and mode, recomputed about every 5 minutes in market hours.
get_market_regime_live - Hold state: a live read on stocks you already hold, with trend state, hold strength and which warning conditions are true right now.
get_hold_state_live - Overnight crypto read: the overnight continuation read, with the BTC 200-day gate, refreshed about every 15 minutes.
get_crypto_night_live
The full board, the buy list and the archive stay paid. You do not need a key to start. This command works with no key and gives a free sample of the board, one market day delayed:

Coil is software and impersonal research, not investment advice. It is long-only, not a managed account, and not a signal service. Markets can lose money, and past performance does not predict future results.
