Basis

alert_link

Destructive

Prepare a price, indicator, chart-drawing, news or calendar alert and get a link that sets it in Basis in one click. Use it whenever the person wants to be told when something happens -- a level breaks, RSI crosses 70, price crosses a trend line, a high-impact ETF headline lands, or an event approaches. Pass exactly one of price, conditions, drawingId or eventTrigger. Give the URL as a link and say in one line what it watches. Nothing is armed until they open it and confirm. Market alerts can run in an open tab; background and event alerts require a signed-in Basis account. The link lasts seven days.

Input Schema

TableJSON Schema

Name	Required	Description
`name`	No	What the person sees when it fires. Chosen for you if omitted.
`when`	No	With price. Omit to pick the crossing from where price is now.
`match`	No	How conditions combine. Default all.
`price`	No	Shorthand for a price-level alert.
`market`	No
`symbol`	No	e.g. BTCUSDT. Defaults to the chart you are building.
`message`	No	Optional note carried into the notification.
`exchange`	No
`drawingId`	No	ID returned by drawing_add. Supports horizontalLine, horizontalRay, trendLine, ray and extendedLine.
`frequency`	No	Default once: fires, then switches itself off.
`timeframe`	No	Bars the alert is checked on. Free presets: 1m, 3m, 5m, 10m, 15m, 30m, 1h, 2h, 4h, 6h, 8h, 12h, 1d, 3d, 1w, 1M. Founder-only custom intervals: 1–1440 minutes (17m), 1–168 hours (7h), 1–365 days (2d).
`conditions`	No	Instead of price. Each {left, operator, right}. An operand is a number, a price field ("close"), an indicator name ("rsi", "ema50"), or {"type":"indicator","studyId":"macd","plotKey":"histogram","params":{}}. rising and falling need no right; changeUpPercent and changeDownPercent take a percent.
`eventTrigger`	No	Instead of market conditions. A news or Basis calendar event filter.
`cooldownMinutes`	No	With frequency cooldown.
