About/Built by an analyst · Open beta

Built by an analyst who got tired of bad tools.

Quant Candles started with one person and a multi-decade corpus of US equity prices that he couldn't reach through any tool he trusted.

US tickers covered

26,000+

We built the dashboard we wanted — fast, honest, no asterisks — and shipped it. Today we're in open beta, collecting feedback from the first wave of users before we open the doors wider.

The data still comes from Financial Modeling Prep. The honesty still does too.

What we believe

Four things we'll defend.

The principles we use to decide what to build, what to charge, and what to walk away from.

  • 01

    Honest data

    We surface every quirk in the corpus. No hidden survivorship bias, no peeking at tomorrow's data.

  • 02

    Premium UX, modest price

    We charge what software costs to run, not what it costs to take the elevator at a hedge fund.

  • 03

    Built for research

    If a feature doesn't help you decide, we don't ship it. And we'll tell you when it doesn't work.

  • 04

    Safety by default

    Your backtests, notebooks, and portfolios are visible only to you unless you share.

Milestones
