Signals for Your Own System

For developers: we POST a structured JSON payload to any public endpoint you control, on every entry and exit.

  1. In CoinLAB, go to Menu → Lab → Signals+ Add signal, pick your strategy, select the WEBHOOK chip, and paste your endpoint URL.
  2. Press SEND TEST — we'll POST a sample with "test": true so you can wire up your handler safely.
  3. Press CREATE, and live signals flow with the same shape:
{
  "id":        "evt_1f3a9c2e77b41d05",
  "v":         1,
  "strategy":  "My SOL strategy",
  "symbol":    "SOL",
  "pair":      "SOLUSDT",
  "side":      "LONG",
  "event":     "entry",
  "action":    "BUY",
  "price":     123.45,
  "leverage":  3,
  "timeframe": "60m",
  "time":      "2026-07-02T14:00:00Z",
  "source":    "ChartLAB Signals",
  "test":      false
}

Read side for direction"LONG" or "SHORT". It's the clearest field, and it's exactly what the human-readable channels (Push, Discord, Telegram) show. The action field carries "BUY" on entries and "SELL" on exits for compatibility, but heads up: a short entry is still "action": "BUY" (it's the entry, not the direction). So if your handler branches, branch on side + event (entry/exit), never on BUY/SELL alone.

The endpoint must be publicly reachable — internal and private addresses are rejected, and HTTPS is strongly recommended. Failed deliveries retry automatically with backoff — retries reuse the same id, so skip any id you've already processed and duplicates can never hurt you. Every send is logged under PAGE → Notifications.

Pointing this at a bot service like 3Commas instead of your own code? There's a dedicated recipe. Prefer a different channel? See all four options.

Signals are information, not orders — CoinLAB never touches your exchange account. Nothing here is financial advice.
