What you need. A Pine Script Strategy (a script that places
orders in the Strategy Tester, not only an indicator that paints a signal), open on a chart
of each symbol you intend to declare, on a TradingView plan that can send webhook alerts.
TradingView decides which plans include webhooks; check your plan before you apply, because
an alert with no webhook delivery cannot reach anyone.
Which chart. Open the feed of the exchange you actually trade, for
example its perpetual chart of BTCUSDT. Triggon reads the symbol from the alert and
normalises it: the exchange prefix and any perpetual suffix are stripped, so a chart symbol
such as EXCHANGE:BTCUSDT.P arrives as BTCUSDT, which is how the
symbol is spelled on Triggon's list. If you use your Strategy's per-symbol connection (recommended, see
alerts), the symbol is fixed by the connection and the alert does not
need to carry it at all.
Spot or futures. Decide which instrument your Strategy trades. Spot means
the coin itself, held outright, with no leverage; futures means perpetual or dated contracts,
where a leverage band applies. The application asks for one of the two, and every Signal is
validated against that declaration.
Alert coverage. A Strategy that alerts on entries but never on exits
produces an incomplete record. Plan an alert for every event you want subscribers to see:
entries, stop and target updates, partial closes, target hits, stop hits and closes.
The TradingView and Pine Script page lists what each alert
can express.
