MEMORY FIELD
Your trades are data. JarvQuant makes them speak.
Every decision stored. Every pattern retrievable. Structured, objective self-improvement. No spreadsheets, no screenshots, no guesswork.
The Model
- No VC funding. No external pricing pressure. Pricing set by the product, not investors.
- Full data sovereignty. Your trades stay on your machine, never shared with external servers.
How it's built
- Built by a solo developer and an AI agent. Lean by design, no overhead passed to you.
- Community-first development: real trader feedback shapes every release.
- No course upsells. No lifestyle content. Just a professional tool for systematic self-improvement.
Why JarvQuant
- Most trading tools only log what happened. JarvQuant shows you why and gives you structured drills to train what went wrong.
- 300+ strategy playbooks. Deliberate Practice challenges. Algorithmic post-trade review. What institutions have had for years, now available for retail traders.
- If you are serious about performance, JarvQuant is the only platform built for that specific goal.

Frequently asked questions
What is JarvQuant?
JarvQuant is a desktop trading simulator and training environment for retail traders. You practise stocks, futures, forex and options against replayed historical data and synthetic markets, then review your own behaviour algorithmically. It runs on Windows, works offline, and has a free tier.
Is JarvQuant a trading simulator?
Yes. You trade against historical market data replayed bar by bar, or against synthetic markets from the JQIV engine. No real money is at risk and no orders are routed to a broker. It's built for deliberate practice: repeating realistic decisions until entries, exits and risk management become consistent.
Can I practise options trading?
Yes. PANTHEON is a synthetic options market with a full chain, live Greeks (delta, gamma, theta, vega), an implied volatility surface and an order book. Practise long calls and puts, covered calls, spreads, straddles, iron condors and assignment mechanics without paying real premium. The Grand Archive adds 64 options entries, from calls and puts through IV crush and strike selection to advanced multi-leg constructions.
How is this different from paper trading with a broker?
Broker paper trading runs in real time, so rehearsing a specific setup means waiting for it to happen again. JarvQuant replays history at any speed — hundreds of setups in an afternoon — and hides future bars so hindsight bias can't creep in. It also adds what brokers don't: algorithmic review of your habits, prop-firm rule simulation, a strategy builder with hard risk constraints, and a journal tied to your metrics.
Can I prepare for a prop firm challenge?
Yes. The Prop Firm Simulator reproduces evaluation constraints — profit targets, maximum daily loss, trailing and end-of-day drawdown — so you learn how you behave under those rules before paying an evaluation fee. Trade Autopsy then surfaces the habits that usually break challenges, like overtrading days and revenge trading after a loss.
Is it free, and is there a trial?
The free tier includes bar-by-bar market replay, data import and a journal capped at 10 entries per type — no card, no time limit. A 7-day Elite trial can be started inside the app and unlocks everything, including PANTHEON and the VANTA AI coach. No payment details are required, and nothing is charged when it ends.
Does it work with MetaTrader 5?
Yes. You can import your MT5 trade history via the data bridge, as well as CSV and Parquet files, and analyse your real trading in Trade Autopsy and the journal alongside your simulated sessions.
What platforms are supported?
JarvQuant is a native Windows desktop application. Every release is published on GitHub and scanned on VirusTotal, with the result linked from the download button above.
