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. T…
Full detail for one catalogue entry: an indicator's parameters and defaults, a formula function's signature, a strategy's parameters, or drawing anchor order/text/style. Call this before passing param…
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, p…
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. lastClosedCandle is one exact OHLC bar; …
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 correlatio…
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 timest…
Read current perpetual funding (fonlama/takas ücreti), open interest and positioning directly by symbol, without loading candles first. Optional ref reuses a fresh derivatives handle. Funding is a tra…
Read current public Hyperliquid positions for a frozen, research-screened whale cohort. Returns account-normalized consensus, participation, agreement, effective-wallet count, single-wallet concentrat…
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 …
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` bind…
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, …
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 te…
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…
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 hist…
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 head…
Which crypto assets a piece of text refers to. Word-bounded, so "button" does not match TON and "operation" does not match OP.
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 c…
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.
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.
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 …
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 wit…
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 …
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_…
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 d…
Draw measured geometry or explain it with text, note, callout or emoji. Points are {time, price} in chart coordinates — time in seconds, matching the candle timestamps a data handle reports. A horizon…
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. Pref…
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…
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 s…
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, w…
Edit only the requested properties of an existing drawing; all others are preserved. For a text edit send just {id,text,fontSize}; never copy the entire stored style or its hex colours. Get the id fro…
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…
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. …
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…
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-s…
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 …
EXECUTED trades only, not resting orders. For current resting liquidity or walls use orderbook_read. Aggressor-side order flow: buy and sell volume separated by who crossed the spread, delta, the foot…
Read current displayed resting bid/ask limit orders on Binance, Bybit, OKX or Hyperliquid perpetuals. Use for resting liquidity, order book/DOM and buy/sell walls, NOT orderflow_read, which reads exec…
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 e…
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 sett…
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, ti…
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, leve…
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 hap…
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 p…
