Most free market APIs hand back raw series and leave the maths to you; here the indicators, risk ratios and correlations are computed server-side, so a question like whether a position is overbought or how badly two holdings move together is one call rather than a spreadsheet. Two limits worth knowing before you lean on it: quotes come from Yahoo Finance through yfinance rather than an exchange feed, and responses are cached, so a 60-second-old quote is by design.
A market data and analysis server built on Yahoo Finance and CoinGecko, with the indicators calculated locally rather than fetched. It covers a single ticker, a basket, or a whole portfolio, and answers with numbers plus a plain-English read of what they say.
- Quotes for one ticker or a batch, with change, volume, 52-week range, P/E and market cap, plus a company's sector, industry, revenue and margins
- Crypto by CoinGecko id: price, market cap, 1h/24h/7d change, all-time-high data and supply, the top coins by market cap, today's trending coins, and a search that finds the id from a name or symbol
- Technical analysis on a ticker — RSI, MACD, Bollinger Bands, SMA 20/50/200, EMA 12/26 — with Golden Cross, Death Cross and overbought/oversold flagged rather than left to be read off
- OHLCV history over a chosen period and interval, with min, max, average price and total volume summarised
- Assets compared side by side on return and volatility over the same window
- Portfolio analysis from SYMBOL:SHARES pairs: current value, weight distribution, sector breakdown and per-position performance
- Risk metrics for a symbol against a benchmark — 95% Value-at-Risk, annualised Sharpe and Sortino, Beta and maximum drawdown
- A correlation matrix of pairwise Pearson correlations across a basket, which is the number diversification actually turns on
- A market snapshot — S&P 500, NASDAQ, Dow, Russell 2000 and the VIX with the day's biggest movers — and the 11 GICS sectors ranked by return through their SPDR ETFs
- Earnings dates with EPS estimate against actual for recent quarters, and the option chain with strikes, volume, open interest, implied volatility and Greeks where available
