Stock market data API: quotes, bars since 2004, movers, news, earnings and research
By Faizan Ahmad. Updated .
The Tradytics stock market data API serves quotes, bars back to 2004, the market's movers and sectors, news, earnings, insider and Congress trades, and research on every US stock and ETF. Pro, $69 a month.
Quotes cover the about 6,000 symbols Tradytics tracks; daily, weekly and monthly bars go back to 2004 for every US stock, with two years of intraday bars for the about 3,000 most traded. Research covers the summary, analysts, earnings, financials, technicals, ownership and fund holdings. Pro includes 300 calls a minute and 50,000 a day, on the same key as options flow, ranked dark pool and dealer exposure.

Why it sits beside options and dark pool data
Stock data on its own is easy to find. Here it shares symbols and New York sessions with every options order from the full OPRA tape, every dark pool block ranked against the stock's year and dealer gamma, delta, vanna and charm, so the bar after a print, the quote next to a wall and the earnings date beside a signal come from one key and one format. Share classes are merged, so GOOG reads as GOOGL. More in the Tradytics research pages.
How it joins the other datasets
- Options flow: the orders printed in a stock the day it gapped.
- Ranked dark pool: top-ranked blocks against the daily bars.
- The scanner: price, technicals, fundamentals, flow and dark pool fields for every stock in one call.
- Probabilities: the chance of each S&P 500 close next to the index's bars.
The backtester runs plain-words strategies on US stocks and ETFs since 2003, split adjusted with dividends paid, and on minute bars.
