Webhook payload format I use for TradingView strategies

Pine alert message:

{
  "secret": "{{strategy.order.alert_message}}",
  "symbol": "{{ticker}}",
  "action": "{{strategy.order.action}}",
  "price": {{close}},
  "sl": {{plot_0}},
  "tp": {{plot_1}}
}

Key thing: Copygram needs `secret` to match the room's webhook secret, and `action` should be `buy` / `sell` / `close`. Anything else gets rejected.
