Tools

get_crypto_context

Claude

Crypto market context for a technical read: BTC/ETH dominance and total/alt market cap, Fear & Greed sentiment, perp funding rate & open interest (positioning/leverage), and the Stablecoin Supply Ratio (dry powder). Use ONLY when analysing crypto assets (BTC, ETH, crypto ETFs). Background context, not the primary signal.

get_event_stats

Claude

Historical base rates for the technical events firing on a ticker today (e.g. RSI below 30, golden/death cross, new 52-week high/low). For each active event: the forward returns (1w/1m/3m/6m/1y) seen historically after similar events across the US universe, with the sample size and an unconditional baseline to compare against. Answers 'what usually happened after this'; small samples warrant caution.

get_instrument_info

Claude

Current snapshot of one instrument: price and recent changes, session state (regular, pre-market, after-hours, closed), 52-week range, and market cap, sector and next earnings date where they apply. Covers US-listed stocks and ETFs and major cryptocurrencies; crypto uses the -USD pair form (BTC-USD, ETH-USD). Forex pairs, futures, options and non-US listings are not covered. Pass a ticker such as 'AAPL', 'SPY' or 'BTC-USD'.

get_intermarket

Claude

Intermarket compass — a first-pass read of the market environment through price-ratio lenses: asset-class rotation (bonds vs stocks, commodities), risk appetite (high-yield vs investment-grade credit, small vs large caps, cyclicals vs defensives), defensive flows (gold, utilities, yield-curve proxy) and the dollar. Each lens reports rising/falling vs its 50-day average plus the 20-day change; overall posture is risk_on, risk_off or mixed. Optional focus= ('gold'|'bonds'|'tech'|'commodities'|'equity'|'crypto') adds lenses specific to that asset class.

get_key_levels

Claude

Compute key price levels for a ticker: support/resistance zones (clustered swing highs/lows with touch counts = how often price reacted there), nearby round numbers, 50/200-day moving averages, and the 52-week high/low. Returns nearest levels above (resistance) and below (support) with distance %. Use these for concrete trigger/target/invalidation levels.

get_macro_context

Claude

Get macro market context: sector P/E ratios, sector performance, US Treasury rates (2Y/10Y/30Y), CPI inflation data. Also provides key inter-market ratios (HYG/LQD, TLT/SPY) from our price data.

get_market_breadth

Claude

S&P 500 market breadth: the percentage of index members above their 50-day and 200-day moving averages, with RSI, trend and 52-week range for each breadth series. A gauge of how broad the current advance or decline is.

get_monitoring_options

Claude

Returns available options for ongoing monitoring — price alerts, idea tracking, watchlist monitoring, scheduled digests — with setup instructions and channels (email/Telegram). Call only when the user asks for ongoing monitoring or notifications; never needed to answer a question.

get_price_history

Claude

Get daily OHLCV price history for a ticker: open/high/low/close/volume. Use period_days to control how far back (default 365, max 3650).

get_relative_strength

Claude

Relative strength of one ticker against another as a price ratio A/B (e.g. GDX/GLD, HYG/LQD, XLK/SPY, NVDA/SPY): how far the ratio sits above or below its 50- and 200-day averages, the ratio's RSI and trend, recent values, and a one-line verdict on which side is leading.

get_sentiment_data

Claude

Market sentiment from Cboe's daily options statistics: put/call ratios for all products, equities, indices, SPX and VIX options, with the underlying call and put volumes, plus a contrarian flag when the equity put/call ratio sits at an extreme.

get_ta_methodology

Claude

Look up MarketCrew's distilled technical-analysis methodology — our own synthesized notes on how to read indicators, structure, levels and regime — to ground an answer in a consistent framework. Returns short passages in our words with relevance scores.

get_technical_indicators

Claude

Calculate technical indicators for a ticker: SMA(50/200), RSI(14), MACD, ATR(14), ADX(14) trend strength, Stochastic(14,3), volume (OBV trend + volume vs 20-day average), RSI/price divergence, Golden/Death Cross, and RSI regime. Computed from daily price history.

public_instrument_news

Claude

Latest news for a ticker — headline, a short summary and a mandatory source_url to the original article (never the full third-party text). Use to ground a market read in recent, attributable news.
