Built by a trader.
Not a SaaS company.
I traded futures for years using the same broken tools every retail trader uses — Excel journals, Discord scanners, vibe-based risk. Nothing about that stack survives contact with a real market regime. So I built the cockpit I needed: regime-gated ranking, an event-sourced journal, an AI copilot grounded in actual trades, and a research stack you can audit. Nexural is that cockpit, opened up.
The cockpit started
as a survival tool.
Most retail traders lose money in the first year. I was one of them. Not because I lacked discipline — I was reading every book, watching every clip, journaling every fill. The problem was the stack. The tools were built for screen-watching, not for thinking. They couldn't tell me when the regime had shifted. They couldn't show me which of my setups statistically shouldn't have been taken. They couldn't ground a copilot in my actual trades.
So I started building. First the journal — not a spreadsheet, an event log. Then the indicators — not patterns, statistics. Then the regime engine — not vibes, a Hidden Markov classifier with composite-z scoring. Then the copilot — not a generic LLM, a retrieval pipeline grounded in my own ledger. Each piece survived a real drawdown before the next was built.
Nexural is the result of those four years compressed into a cockpit that's now in production for me — and as of this quarter, opened up to traders who want what I'd built. There is no marketing department. There is no investor deck. The product is the receipt. The book is free. The repos are public. The track record is auditable. If the cockpit doesn't make you a better trader within a quarter, you should leave — and I built the platform to make leaving frictionless.
The point of Nexural isn't to make you depend on Nexural. It's to make you the operator the market actually rewards — whether you stay on this platform forever or graduate to your own desk.

- 2021 · Q1Started journaling every futures trade in a spreadsheet. 600 fills in, the spreadsheet stopped helping.
- 2021 · Q4Lost a month of edge to a regime shift I didn't see. Started reading every paper on Hidden Markov regime classification I could find.
- 2022 · Q2First version of the regime engine ran on my laptop. Stopped trading by gut. Equity curve started behaving.
- 2023 · Q3Wrote the indicators in TradingView. Open-sourced them. Three of them ranked in the top 1% of the platform inside six months.
- 2024 · Q1Built the journal: event-sourced, trade-replayable, copilot-annotated. Migrated my entire history. Realized 80% of my drawdowns came from one tagged setup.
- 2025 · Q2Wired QuantFlow into NinjaTrader 8 over an encrypted ZeroMQ bridge. Sub-200ms order path. First fully-automated session.
- 2025 · Q4nowFriends were asking for access. I said yes. Nexural goes from 'my cockpit' to 'the cockpit' — opened up to traders who want what prop desks have.
Five rules.
Every commit. Every quarter.
These aren't aspirations. They're the filters every PR runs through and every roadmap item is tested against. If one of them ever stops being true, the platform stops being Nexural.
Statistics over stories.
Every claim a setup makes is backed by a number you can audit — composite-z, walk-forward score, regime-conditioned win rate. If the math doesn't survive scrutiny, the setup doesn't ship.
Receipts over marketing.
Track record is public, signed, and version-controlled. The book is free. The indicators are open-source. The research repos are auditable. Nothing about Nexural depends on you trusting a screenshot.
Built in the open.
Five public repos. A live changelog. A status page that tells you when something is broken before you notice. The platform you use is the platform we trade — same code, same regimes, same alerts.
Regime over signal.
The same setup is a 70% winner in trend-long and a 35% loser in chop. If a tool can't tell you which regime you're in, it can't tell you anything useful. Every Nexural surface is regime-aware by default.
Make leaving free.
No retention games. No vendor lock-in. Bulk-export your journal as JSON or CSV anytime, paid or not. We win when you stay because the cockpit makes you better — not because exit is painful.

Trader · author · author of this software.
I trade futures full-time and write the software I trade with. That's the whole résumé. No hedge fund pedigree, no "ex-Goldman" bullet, no investor backing. Just five years of fills, four years of journaling, and three years of compressing what I learned into a cockpit serious traders can actually use.
Nexural is the second half of that work. The first half was The Asymmetric Investor — a 37-chapter book on how to think about positioning, regime, and risk when you don't have a desk behind you. It's free. Always was. Always will be.
The software is what comes after the book — the operationalized version of every lesson the book teaches. Indicators, journal, ranker, copilot, automation. Every line shipped after surviving a real drawdown in a real account.
