Dual-sourced quote and fundamentals for one US ticker.

Asks TradingView (scanner + Yahoo quote engine) and Finviz in parallel for price, change, previous close, 52-week range, P/E, RSI and volume, compares them, and returns the merged result. Finviz's deeper fundamentals — the 84-field snapshot, company profile, peers and after-hours print — ride along, each labelled with the provider that supplied it.

Args: symbol: Ticker as written for either source (AAPL, BRK.B, BRK-B).

Returns: Envelope whose data_provider is BOTH when both providers answered and the compared fields agree, TRADINGVIEW/FINVIZ when only one answered (the notice then states the data is not cross-verified), or NONE when both failed.

Dual-sourced prices for several tickers at once.

Each ticker is looked up on both TradingView's scanner and Finviz's screener; the per-row data_provider says whether that particular ticker was confirmed by both, by one, or by neither.

Args: tickers: Comma-separated symbols, e.g. "AAPL,MSFT,NVDA".

Returns: Envelope whose data is a list of rows, each with symbol, price, change_percent and its own data_provider.

Run the US stock screener on both providers and cross-check the rows.

TradingView ranks the entire market server-side (sort_by ∈ market_cap, dividend_yield, change, price); Finviz can be narrowed with its own filter language (finviz_filters, e.g. cap_smallover,sec_technology or t=AAPL,MSFT). Tickers that both providers return are compared on change percentage.

Args: country: TradingView market (america, turkey, …). sort_by: TradingView sort key. limit: Rows to request from each side (≤200 on Finviz). finviz_filters: Optional Finviz filter expression.

Returns: Envelope with rows (TradingView ranking) and a per-row finviz_match showing whether Finviz agreed.

Dual-sourced level and day change for the major US indices.

Covers S&P 500, Dow, Nasdaq Composite, Russell 2000 and VIX. Finviz and TradingView/Yahoo use different tickers for the same index; they are mapped to one canonical name before comparison.

Returns: Envelope whose data.indices is keyed by canonical index (SPX, DJI, COMP, RUT, VIX), each value carrying level, change_percent and its own data_provider.

Dual-sourced headlines for one ticker.

Finviz supplies headlines with the price reaction around each item (the day-of move and, when the story broke after the close, the next session's move). TradingView's side is the provider's licensed news feed. Headline titles are matched across both to report overlap.

Args: symbol: Ticker. limit: Maximum headlines per provider. include_reactions: Ask Finviz for price-reaction columns.

Returns: Envelope with data.items (Finviz ordering, which carries reactions) and data.overlap describing how many TradingView headlines were also present on Finviz.

Dual-sourced options chain for one expiry.

Finviz and the TradingView provider's Yahoo options endpoint are both queried. Contracts are matched by strike and their volume/open-interest compared, so an agent can see whether the two sources agree on open positioning.

Args: symbol: Underlying ticker. expiry: YYYY-MM-DD; None uses each provider's nearest expiry.

Returns: Envelope with data.calls/data.puts (Finviz, which carries full greeks), the TradingView chain, and data.overlap.

Dual-sourced earnings calendar and history for one ticker.

Finviz owns the detailed tables (reported quarters, estimate revisions, fundamental series, post-earnings reactions); TradingView's scanner confirms the next/last earnings timestamp. The two dates are compared and reported.

Args: symbol: Ticker.

Returns: Envelope with data.next_earnings_date, the Finviz tables and a date_comparison block.

Dual-sourced pre-/post-market price for a US stock.

Finviz exposes the after-hours print on the quote page; the TradingView provider derives pre/regular/post prices from 1-minute Yahoo candles. The after-hours price and change are compared.

Args: symbol: Ticker.

Returns: Envelope with data carrying pre_market, regular, post_market and the Finviz after-hours block.

Technical analysis with the key readings cross-checked against Finviz.

TradingView computes the full indicator stack (RSI, MACD, EMAs, Bollinger, ATR, ADX, structure, trade setup). Finviz's snapshot independently provides price, RSI(14), ATR(14) and the 52-week range, which are compared here.

Args: symbol: Ticker. exchange: TradingView exchange prefix (NASDAQ, NYSE, BIST, …). timeframe: 5m, 15m, 1h, 4h, 1D, 1W, 1M.

Returns: Envelope whose data.analysis is the TradingView analysis and data.cross_check holds the Finviz comparison.

SEC filing history for a ticker (Finviz-only, single-source).

TradingView has no filing feed, so this capability cannot be cross-verified. The response is labelled FINVIZ and the notice says so.

Args: symbol: Ticker. page: 1-based page. page_size: Rows per page (1-100). forms: Optional SEC form filter, e.g. "10-K,10-Q".

Returns: Envelope with the filing rows plus has_more.

Insider trades, institutional holders and short interest (Finviz-only).

Combines three Finviz datasets that no other provider here offers: Form-4 insider transactions with monthly buy/sell aggregates, institutional positions, and FINRA short-interest history.

Args: symbol: Ticker. limit: Max rows per table.

Returns: Envelope labelled FINVIZ with insider, institutional and short_interest blocks (whichever Finviz could serve).

Finviz peer group for a ticker (Finviz-only, single-source).

Args: symbol: Ticker. limit: Maximum peers.

Returns: Envelope labelled FINVIZ with peers.

Finviz's own explainer for why a ticker moved (Finviz-only).

Args: symbol: Ticker.

Returns: Envelope labelled FINVIZ with headline, summary, sentiment and catalyst flag.

Rendered PNG candlestick chart for a ticker (Finviz-only).

TradingView's provider computes charts as text analysis, not images, so a PNG is Finviz-only and labelled as such.

Args: symbol: Ticker. period: d daily, w weekly, m monthly. chart_type: c candle, l line, h heikin-ashi. scale: l linear, log logarithmic. width: Pixel width. height: Pixel height.

Returns: Envelope labelled FINVIZ with the saved PNG path and dimensions.

Dilution-risk model: share count, float and cash runway (Finviz-only).

Args: symbol: Ticker.

Returns: Envelope labelled FINVIZ; model_available says whether Finviz flagged the company as dilution-prone.

Finviz's full screener filter catalogue (Finviz-only).

Returns: Envelope labelled FINVIZ with the machine-readable filter list.

Args: movement: gainers or losers. exchange: TradingView venue (KUCOIN, BINANCE, BYBIT, …). timeframe: 5m, 15m, 1h, 4h, 1D, 1W, 1M. limit: Rows to return.

Returns: Envelope labelled TRADINGVIEW with the ranked rows.

Curated futures watchlist with levels (TradingView-only).

Backtest a strategy on a symbol (TradingView-only, single-source).

Finviz has no OHLCV history endpoint, so this cannot be cross-verified. The response is labelled TRADINGVIEW and the notice says so.

Args: symbol: Ticker or coin. strategy: One of rsi, bollinger, macd, ema_cross, supertrend, donchian, rsi_pullback, keltner_breakout, triple_ema. period: 6mo, 1y, 2y, 5y, … initial_capital: Starting cash. interval: 1d or 1h. include_trade_log: Include the per-trade log. include_equity_curve: Include the equity curve.

Global FX, crypto, index and ETF snapshot (TradingView-only).

Finviz covers only the four US indices, so the broad snapshot is single-source. Use market_indices for a cross-verified index read.

Returns: Envelope labelled TRADINGVIEW grouped by asset class.

Bitcoin market health: trend, dominance proxies and volatility.

Returns: Envelope labelled TRADINGVIEW.

News-based sentiment for a symbol, with no API key required.

Prefers the licensed Marketaux entity sentiment when MARKETAUX_API_TOKEN is set. Without a token it scores Finviz headlines locally (VADER with a financial lexicon) — deterministic, offline and free. Either way the payload names the backend in provider/scoring and never fabricates a score when there is no material to score.

Args: symbol: Ticker. category: News category (used by the Marketaux path only). limit: Headlines to analyse.

Returns: Envelope labelled TRADINGVIEW whose data carries sentiment_score, sentiment_label, the bullish/bearish/neutral counts and the strongest headlines.

Egyptian Exchange overview (TradingView-only).

Returns: Envelope labelled TRADINGVIEW.

Technical analysis, news and sentiment in one call, cross-checked on price.

Runs the TradingView technical read plus news sentiment, then pulls Finviz's latest close to confirm the price the analysis was built on. This is the one composite that can legitimately return BOTH: the price leg is dual-sourced, while the analysis and sentiment legs remain single-source and are labelled per field.

Sentiment needs no API key: Marketaux is used when MARKETAUX_API_TOKEN is set, otherwise Finviz headlines are scored locally. The data.news leg stays Marketaux-only, so it is empty (and says why) without a token.

Args: symbol: Ticker. exchange: TradingView exchange prefix. timeframe: TradingView interval.

Returns: Envelope with data.analysis, data.sentiment, data.news and data.price_cross_check.

Probe both upstreams and report whether either provider's API drifted.

Every other tool reads the cached verdict from this monitor and adds a warning when a provider's upstream schema has changed or is down. Call this with refresh=True to force an immediate re-probe (otherwise the cached result is reused for TAPEBASIS_HEALTH_TTL seconds).

Args: refresh: Force fresh probes instead of using the cached verdict.

Returns: Envelope whose data carries providers (OK/DRIFT/ DOWN/UNKNOWN per provider), degraded, issues and the per-probe baseline comparison.

List every tool, which providers back it, and how it is cross-checked.

Useful for an agent that needs to know whether a given capability is dual-sourced (BOTH), single-sourced (TRADINGVIEW/FINVIZ) or analysis generated by one provider only. This tool performs no upstream requests.
