Overview

AI-generated overview

Basis gives an assistant crypto market data, indicator and backtest computation, order flow, news and calendars, plus tools to build and publish a shareable web

What you can do
Search and describe the catalogue of indicators, formula functions, built-in strategies and drawing tools, and read crypto domain guidance and measured findings. Load candle history and compute indicators, formulas, backtests, strategy research, position sizing and historical trade analogues. Analyse multi-asset relationships, market dominance, derivatives funding and open interest, Hyperliquid whale positions, executed order flow and resting order books. Screen instruments and replay screens historically, and scan for day-trade candidates. Read recent and archived crypto news, detect assets in text, and list upcoming or past macro and market calendar dates. Build a chart: set instrument,
When to use it
Useful when someone wants crypto market analysis backed by computed indicators, backtests, order flow or screening rather than guesses, and wants the result delivered as a chart link they can open. Also suited to questions about funding, dominance, whale positioning, news or event calendars.
Requirements
Remote streamable HTTP endpoint at the server's own site; no account, API key, environment variable or header is declared. Network access to the endpoint is required.
Before you install
The chart tools change the chart being built for the person, and drawing_delete is irreversible, so the user is asked first. Backtests, screen replays and trade analogues are historical simulations with costs, not proof of an edge; news impact scores are keyword heuristics. Market data comes from third-party venues and aggregate sources.

Installation

In SourceWeft

  1. Open Basis in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/com.basischarts%2Fbasis/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Tools

44

catalog_describe

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 parameters you have not seen.

Parametersidrequiredkind

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 NOT measured, marked as such. Call it before analysing a chart pattern, interpreting an indicator level, designing a strategy or judging a result that looks strong. It carries no live market data.

Parameterstopicrequired

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. lastClosedCandle is one exact OHLC bar; high/low are WHOLE-WINDOW wick extremes with highAt/lowAt timestamps; from/to are window boundaries, not swing anchors. bars includes a possible forming bar: request N+1 for N closed bars and check closedBars. Defaults to whatever is on the chart.

ParametersbarsmarketsymbolexchangetimeframewithDerivatives

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 lead/lag diagnostics and a rolling log-price spread z-score versus a benchmark. Use this for BTC correlation, beta, pairs and relative-strength work; price-level correlation is deliberately not reported.

ParametersbarsmarketsymbolsrequiredexchangebenchmarktimeframerollingWindow

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 context. This is a current snapshot, not a historical dominance backtest series.

Takes no parameters.

market_derivatives

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 transfer between longs/shorts, NOT a maker/taker trading commission. Returns decimal and percentage rates, actual settlement interval and optional payment scenario.

ParametersrefsidemarketsymbolexchangetimeframenotionalQuote

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 fills for the focus symbol. Use this for whale/smart-money positioning as one evidence family, never as a standalone signal.

ParameterssymbolflowHourstopSymbolsmaxFlowWalletsincludeRecentFlowminimumDayVolumeUsd

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 against its actual scale. Pass a symbol to load and compute in one call, or a handle to reuse data. The forming bar is excluded unless you ask for it.

ParametersrefplotmarketparamsreducesymbolstudyIdrequireddataModeexchangetimeframeincludeForming

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 is the result.

ParametersrefmarketreducesymbolexchangetimeframeexpressionrequiredparametersincludeForming

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, which is a search whether or not it is called one. It ranks only on a selection window, checks several subperiods, leaves an embargo, reveals held-out performance, doubles costs as a stress test, compares buy-and-hold, and corrects the selected Sharpe for every strategy/symbol/timeframe combination tried.

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 chart.

ParameterssiderequiredstoprequiredentryrequiredequityrequiredfeeBpstargetsleveragefundingRateriskPercentrequiredholdingHoursfundingPerDaymaintenanceMarginRate

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 compare similar wins and failures, never as proof of an edge.

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.

ParametersassethourslimitminImpact

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.

Parameterstextrequired

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 what landed. Finish with chart_link to give the person something to open.

Takes no parameters.

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.

Parametersmarketsymbolrequiredexchange

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.

Parameterstimeframerequired

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 sharing draft that needs human review.

ParameterschartTyperequired

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 a sharing draft that needs human review.

ParametersparamsstudyIdrequired

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 the chart you are building; finish with chart_link, or analysis_prepare for a sharing draft that needs human review.

ParametersparamsrequiredinstanceIdrequired

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 sharing draft that needs human review.

ParametersinstanceIdrequired

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.

ParametersinstanceIdrequired

drawing_add

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 horizontal line needs one point; a trendline or box needs two. Measured anchors 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. A note/text position or callout second anchor is layout, not a measured price; place it in spare chart space. 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. Changes the chart you are building; finish with chart_link, or analysis_prepare for a sharing draft that needs human review.

ParametersreffilltexttoolrequiredcolorwidthlevelspointsrequiredsymbolopacityarrowEndfontSize+15 more

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 market_candles computations rather than visual guesses. For a highest-high/lowest-low retracement use anchorMode high-to-low or low-to-high with ref and lookback: the tool selects exact CLOSED-candle wick coordinates. Do not substitute window start/end times. Changes the chart you are building; finish with chart_link, or analysis_prepare for a sharing draft that needs human review.

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 highlighter for translucent emphasis and brush for circles, paths and marks. Changes the chart you are building; finish with chart_link, or analysis_prepare for a sharing draft that needs human review.

ParametersreffillmodetextcolorwidthsymbolopacitystrokesrequiredarrowEndfontSizetextBold+14 more

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 instead only when the user also wants quantity and risk calculations. Without explicit timestamps the illustrative box spans recent closed candles for visibility, not future bars or an executed historical trade. Changes the chart you are building; finish with chart_link, or analysis_prepare for a sharing draft that needs human review.

ParameterssiderequiredstoprequiredentryrequiredsymboltargetrequiredtoTimebarsWidefromTimetimeframe

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 program id so later analysis reads the same plan the user sees. Without explicit timestamps this illustrative scenario spans recent closed candles for visibility, not an executed historical trade. Changes the chart you are building; finish with chart_link, or analysis_prepare for a sharing draft that needs human review.

drawing_style

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 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 chart you are building; finish with chart_link, or analysis_prepare for a sharing draft that needs human review.

ParametersidrequiredfilltextcolorwidthsymbolopacityarrowEndfontSizetextBoldwrapTextlineStyle+12 more

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.

Parametersidrequiredsymbol

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 doing X right now". It fetches history for every instrument in the universe, so use exactly the requested filters. For "5 coins with RSI above 50", call rules: [{left:{kind:"indicator",studyId:"rsi"},operator:"above",right:50}], limit:5. Use above for a current state; crossesAbove only for a fresh crossing. limit controls returned matches, universeSize controls how many markets are searched.

ParametersnamelimitlogicorderquoterulesrequiredmarketsortByexchangelookbacktimeframeuniverseSize+1 more

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 deep-dive only the shortlist with derivatives/order-flow tools. For a general scalp request use style:"scalp" and omit longRules/shortRules to use transparent RSI/EMA defaults. For explicit user filters use screener_run instead. Near misses never satisfy all rules.

ParametersnamequotestylemarketexchangelookbacklongRulestimeframeshortRuleslimitPerSideuniverseSizemanualSymbols

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 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.

ParametersnamelogicquoterulesrequiredfeeBpsmarketexchangelookbackdirectiontimeframeslippageBpsmaxPositions+2 more

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 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.

Parametersdayslimitimpactsymbol

orderflow_read

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 footprint by price level, the point of control, and absorption or stacked imbalance. Measured from the venue aggressor tag, not inferred from bar direction — use it when the question is who is being aggressive, which candles cannot answer. For one candle pass candleTime, which reads exactly that bar; otherwise it reads the last `minutes`. Report coveredMinutes, not the minutes asked for.

ParameterslevelsmarketsymbolendTimeminutesexchangetimeframebucketSizecandleTimeincludeSignals

orderbook_read

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 executed trades. Returns timestamp, spread, largest displayed levels and bounded depth coverage. Not historical depth, hidden stops or guaranteed support.

ParameterslevelsmarketsymbolexchangenotionalQuote

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 occurred. No full article text.

Parametersassetlimittopicbefore

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, forecast or previous economic values. No historical funding or halving feed. Use calendar_upcoming for future events.

Parameterstofromrequired

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 describe them. Build first with the chart tools, or pass symbol, timeframe, indicators and levels to build and look in one call. Pixels are for shape; quote numbers from the figures or the data tools.

Parametersbarssizelevelsmarketsymbolexchangetimeframeindicators

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 explicitly publish; you cannot publish or post on their behalf. Chart annotations are included. Do not include private account information.

Parametersbodyrequiredtitlerequiredlevelsmarketsymbolcaptionrequiredexchangetimeframeindicators

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 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.
