What to use instead

Most people do not arrive at a catalogue to browse. They arrive because something they relied on shut down, changed its terms, or costs more than the job is worth. One page per product, with what in this catalogue does that job now.

• Bloomberg Terminal

  Still running

  The institutional standard — data, news, analytics, research and a messaging network on one leased workstation, sold by annual subscription at a price Bloomberg does not publish.

• IEX Cloud

  Shut down

  A REST market data platform from IEX Group — US quotes, fundamentals, news and reference data, billed in credits — aimed at developers rather than institutions.

  6 replacements

• Portfolio Visualizer

  Still running

  The browser tool most people reach for to backtest an asset allocation — plus Monte Carlo, an optimiser, Fama-French factor regression and tactical allocation models, behind a free tier and two annual plans.

  7 replacements

• Quandl

  Terms changed

  A data marketplace and Python client that was acquired by Nasdaq in 2018, rebranded as Nasdaq Data Link, and whose free WIKI end-of-day stock dataset stopped being maintained years before that.

  6 replacements

• Quantopian

  Shut down

  A free hosted platform for writing and backtesting Python strategies against bundled US equity data, paid for by a crowd-sourced hedge fund that licensed the best algorithms from its own community.

  6 replacements

• TradingView

  Still running

  The browser charting platform most retail traders default to — 50-plus markets under one symbol search, Pine Script, server-side alerts and order entry through a connected broker.

  8 replacements

• Yahoo Finance API

  Terms changed

  There is no official Yahoo Finance API and has not been one since 2017 — what people call by that name is a set of undocumented endpoints behind the website, read without a licence.
