• catalog_search

  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…

• catalog_describe

  Full detail for one catalogue entry: an indicator's parameters and defaults, a formula function's signature, or a strategy's parameters. Call this before passing parameters you have not seen.

• crypto_quant_guide

  Domain knowledge for a crypto analysis: the constraints of the topic, the Basis tool chain, and — the part worth calling for — findings Basis has actually measured, each with its sample and verdict, plus the conventional readings it has…

• market_candles

  Load price history and return a handle to it, plus a summary. The bars themselves are deliberately not returned — pass the handle to the compute tools instead. Defaults to whatever is on the chart.

• market_relationships

  Professional multi-asset relationship analysis on timestamp-aligned closed-bar log returns. Returns a correlation matrix plus rolling correlation, OLS beta/alpha, R-squared, upside/downside correlation, relative performance, one-bar…

• market_dominance

  Current crypto market-cap structure from a server-cached aggregate source: real BTC and ETH dominance, total market cap/volume, tracked stablecoin share and leading asset shares with source and timestamps. Use this for BTC.D/rotation…

• market_derivatives

  Funding, open interest, positioning and taker flow for a loaded contract. Venues publish different subsets; anything a venue does not publish comes back as unavailable rather than zero.

• hyperliquid_whale_read

  Read current public Hyperliquid positions for a frozen, research-screened whale cohort. Returns account-normalized consensus, participation, agreement, effective-wallet count, single-wallet concentration, liquidity and optional recent…

• indicator_compute

  Run any indicator in the catalogue. Returns EVERY output series it has — Donchian gives three bands, MACD gives line, signal and histogram — each reduced, plus the indicator's own conventional levels so the reading can be interpreted…

• formula_evaluate

  Evaluate a Basis formula expression over a loaded window. Functions are listed by catalog_search kind=formula; series named open, high, low, close, volume, returns and more. Multi-line with `let` bindings is supported; the last expression…

• backtest_run

  Backtest one built-in strategy with one set of parameters. Fills happen at the next bar's open and costs are charged per side. Returns risk-adjusted metrics alongside the raw return — judge on those, not on total return.

• strategy_research

  Run one chronological research experiment across many built-in strategies, instruments and timeframes. Use this for broad discovery instead of many backtest_run calls — and in particular instead of testing one strategy on coin after coin…

• position_calculate

  Risk-first position sizing with quantity, notional, margin, effective leverage, fees, funding, breakeven, liquidation estimate, target R multiples and warnings. Use position_plan_on_chart instead when the user should see the plan on the…

• trade_experience_retrieve

  Retrieve compact historical trade analogues for the current market state. Plans are deterministic synthetic templates, while fills, stop/target ordering, MAE/MFE and outcomes are settled on later historical candles with costs. Use it to…

• news_recent

  Recent crypto headlines with an impact score and the assets each one touches. Impact is a keyword heuristic, not a judgement about the market. Pass hours for "today" or "the last 24 hours"; every headline says how old it is.

• news_detect_assets

  Which crypto assets a piece of text refers to. Word-bounded, so "button" does not match TON and "operation" does not match OP.

• chart_state

  The chart you are building for this person: venue, symbol, timeframe, chart type, every indicator with its instance id and parameters, and every drawing. Start here when you need an instance id, and call it again after changes to confirm…

• chart_set_instrument

  Point the chart at a market. Venue and symbol as the exchange writes them, e.g. BTCUSDT on binance. This changes the chart you are building, which the person opens through chart_link.

• chart_set_timeframe

  Change the chart timeframe, e.g. 15m, 1h, 4h, 1d. Changes the chart you are building; finish with chart_link, or analysis_prepare for a sharing draft that needs human review.

• chart_set_type

  Change how price is drawn — candles, heikin ashi, line, renko, footprint and others. A wrong id is refused, and the refusal lists every one that works. Changes the chart you are building; finish with chart_link, or analysis_prepare for a…

• chart_add_indicator

  Put an indicator on the chart. studyId is an id or a common name ("ema20", "bollinger"); catalog_describe lists parameters. Omitted ones use the default. Changes the chart you are building; finish with chart_link, or analysis_prepare for…

• chart_update_indicator

  Edit the parameters of an existing indicator instance. First call chart_state to get its instance id; use catalog_describe for supported parameters. To delete use chart_remove_indicator, to hide/show use chart_toggle_indicator. Changes…

• chart_remove_indicator

  Delete an indicator instance from the chart. Use chart_state to find its instance id. To temporarily hide it instead, use chart_toggle_indicator. Changes the chart you are building; finish with chart_link, or analysis_prepare for a…

• chart_toggle_indicator

  Hide or show an indicator without removing it — useful for comparing a chart with and without something. Changes the chart you are building; finish with chart_link, or analysis_prepare for a sharing draft that needs human review.

• drawing_add

  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…

• fibonacci_draw

  Draw a Fibonacci study directly on the chart with exact candle coordinates and optional custom ratios. Supports retracement, extension, channel, time, fan, circle, spiral, arc and wedge variants. Prefer swing timestamps/prices returned by…

• drawing_freehand

  Create one or more precise freehand strokes as a single undoable composition. A stroke accepts arbitrary chart points; line accepts two endpoints; ellipse and rectangle accept two opposite corners and are generated smoothly. Use…

• position_draw_on_chart

  The chart-only long/short position drawing tool. Draw an entry, stop and target box immediately when those price levels are known. It needs no account equity or risk percentage, performs no position sizing and places no order. Use…

• position_plan_on_chart

  Calculate a risk-first long/short position and draw the entry, stop and first target directly on the live chart. The drawing retains quantity, notional, margin, costs, liquidation estimate, targets, warnings and an optional sandbox…

• drawing_style

  Change how an existing drawing looks. Get the id from chart_state. Use it to keep several drawings apart — a measured level and a projected one should not be the same colour, and a reader has only the picture to tell them by. Changes the…

• drawing_delete

  Delete a drawing. This cannot be undone — the shape is not recoverable — so the user is asked first. Changes the chart you are building; finish with chart_link, or analysis_prepare for a sharing draft that needs human review.

• screener_run

  Scan the venue's listed instruments for ones matching conditions, instead of looking at the open chart. Rules combine price fields, any indicator plot, or a formula expression, with ALL/ANY matching. This is the tool for "which coins are…

• daytrade_opportunity_scan

  Run one symmetric long/short scan over the same top-volume universe and return rule-independent breadth, 24h liquidity semantics and ranked directional candidates. Use this first for comprehensive day-trade or scalp discovery; then…

• screener_backtest

  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…

• calendar_upcoming

  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…

• orderflow_read

  Aggressor-side order flow: buy and sell volume separated by who crossed the spread, delta, the footprint by price level, the point of control, and absorption or stacked imbalance. Measured from the venue aggressor tag, not inferred from…

• news_history

  Read archived crypto headlines, newest first, with source links. Use news_recent for live headlines. Paginate with nextBefore (ISO timestamp). Archive coverage starts when Basis began collecting; an empty page does not prove no news…

• calendar_history

  Past calendar dates: FOMC rate decisions, US CPI and non-farm payroll releases from the Fed's and BLS's published calendars (February 2025 on), plus reconstructed conventions (options expiry, CME settlement). Dates only: NOT actual…

• chart_link

  Publish the chart and get a URL the person can open in Basis. Call it at the end of any answer about a market: the chart is half the answer. Either build first with the chart tools, or pass symbol, timeframe, indicators and levels here to…

• chart_image

  See the chart you are building: returns a PNG of it -- candles, volume, every indicator and drawing -- rendered the way Basis draws it, plus the exact figures it shows. Use it to check structure, levels and what you drew before you…

• alert_link

  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…

• analysis_prepare

  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. The person must open it, edit/review and…

• founders_preview

  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…
