Les 43 outils

• alert_link≈ 1249 tokens

  Prepare a price, indicator, chart-drawing, news, calendar or Founder whale-group 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.

  Prepare a PRIVATE sharing package of the current chart image, editable analysis and social caption. Only use when asked for something shareable. Returns a private review link, NOT a public link.

  Scheduled events ahead: FOMC rate decisions, US CPI and non-farm payrolls from the Fed's and BLS's published calendars, the next funding settlements for a contract, the Bitcoin halving projected from live block height, difficulty retargets, monthly options expiry and CME settlement. Every row states where its date came from — live, an official schedule, a published rule, an estimate, or the user — because a halving projected from block arrival and an expiry fixed by convention are not equally certain. Use it before saying anything about what happens next; nothing else here looks forward.

  Search what Basis can do: indicators, formula functions, built-in strategies, the extra series available inside strategy expressions, and the drawing tools with the number of anchors each one takes. Exact counts are in the system prompt catalogue. Use this before assuming something does or does not exist — and always before drawing, because a drawing tool id you guessed is refused.

• drawing_add≈ 759 tokens

  Draw on the chart. Points are {time, price} in chart coordinates — time in seconds, matching the candle timestamps a data handle reports. A horizontal line needs one point; a trendline or box needs two. Both numbers must be copied from a tool result — a summary's max with its maxAt, a crossing with its time — never read off your own prose or carried over from a different computation. The result echoes back what was drawn: check it against the figures you are about to quote, because a line that disagrees with the paragraph beside it is worse than no line.

  What Basis Founders adds to this connection, and the live totals a non-member may see: how many screened Hyperliquid whales are tracked, their combined book and the coin most of them hold. Founders is an optional paid membership; this tool is free and always answers. Use it when a question needs whale positions, whale or gamma levels, more than 30 days of derivatives history, or a stock or commodity on Hyperliquid or Binance.

• screener_backtest≈ 634 tokens

  Historically replay a cross-sectional screen at every bar. Matching instruments form an equal-weight long or short portfolio, entered at the next bar open and held to the following bar open, then re-screened. Use this when the question is whether repeatedly trading screener matches worked — a single-symbol backtest of coins that match today is not a substitute. Costs follow actual portfolio turnover, so an unchanged holding is not charged as a fresh round trip.
