QuantCrystal · Pro tier
The algorithmic layer of MarketCrystal.
MarketCrystal is where Mark reads the market in plain language, free. QuantCrystal is where the engine underneath it — Trismegistus — is put to work: simulating strategies, backtesting them through a real execution path, and keeping a scored record of what it predicted.
Nothing here is a track record. No performance figures are published on this site because none have been earned in public yet.
What you get
Four things, done without flattery.
Monte Carlo simulation
Your strategy's equity curve is one draw from a distribution. We resample it in blocks to show the other draws — the outcome spread, the drawdown percentiles, and the probability the account is dead before the edge shows up.
Read more →Backtesting through a real engine
No vectorized approximations of fills. Signals go through the same execution engine that would trade them, with the same order types, the same costs, and parameters frozen before the test window opens.
Read more →Curated datasets
Survivorship-free equities, full-market daily bars, crypto tick archives, macro series, and filings — assembled so a backtest is not quietly reading a universe that only contains the survivors.
Read more →Bot-building guidance
Advisory, not a signal service. Help turning a hypothesis into a specified, testable, risk-bounded system — and an honest read on when the answer is that the edge is not there.

Trismegistus
Trismegistus is the analysis engine behind both sites. On marketcrystal.ai it speaks through Mark, in prose, for free. Here it is exposed as machinery: the regime classifier, the nowcasts, and the ledger that keeps score.
Markets do not have one behaviour. The engine classifies the current environment rather than assuming a single stationary process, because a strategy's expectancy is conditional on the regime it runs in.
Estimates of present-state conditions from data that is already observable, rather than forecasts of distant outcomes. The near term is where the signal-to-noise is least hostile.
Every prediction is written down before the outcome, with its resolution criteria, and scored when it resolves — hits and misses alike. A forecast that is never graded is marketing, not research.
Architecture status
The public engine API is not deployed. The intended shape is a Railway-hosted Python service that owns simulation, backtesting, and ledger resolution, with this site as a static front end against it. Endpoints, rate limits, and latency targets are unset — this page will be updated with specifics rather than promises.
Pricing
Two paid tiers.
The free reading of the market stays free on MarketCrystal. What the paid tiers cover is the tooling that consumes compute and licensed data — simulation runs, backtest jobs, dataset access, and engine output.
Price boards, Mark's written analysis, and the newsletter. Lives at marketcrystal.ai and stays free — it is not a trial of this.
- Cost-per-unit price boards
- Mark's market commentary
- Newsletter
- No account required
The simulation and backtesting workbench. For traders who want to test their own systems properly rather than consume someone else's calls.
- Monte Carlo simulation tools
- Backtest reports through the real execution engine
- Dataset access as each set is released
- Full methodology documentation
Everything in Pro, plus the engine's own output — what Trismegistus classifies, forecasts, and gets scored on.
- Everything in Pro
- Trismegistus signals and regime calls
- Resolution-tracked prediction ledger
- Engine API access when it ships
- Bot-building advisory
Access begins at launch
Neither paid tier is purchasable today. There is no checkout, no billing, and no account system — the waitlist is the current and only step. Prices above are the intended launch prices in USD per month; features are described as intended scope, and anything not yet built is marked as such in its tier. Billing terms will be published before any charge is made.
Waitlist
Get told when it opens.
One message when access opens. No drip sequence, no urgency theatre, no resale of your address.
