NexusTrade vs Chat·Backtest
NexusTrade is a no-code, AI-native algorithmic trading platform where you describe a strategy in plain English to an agent called Aurora, or assemble it in a visual condition builder, then backtest, optimize, paper trade and deploy it to a connected brokerage. It also runs a marketplace where users can publish and monetize strategies.
Everything below about NexusTrade was read from their own site on August 6, 2026, and every row links its source. Pricing and features change — if you find something out of date here, tell us and we’ll fix it.
Feature by feature
| Feature | NexusTrade | Chat·Backtest |
|---|---|---|
| What it is | An AI-native, no-code algorithmic trading platform. Their FAQ is explicit about the boundary: "Is NexusTrade a brokerage? No... To trade with real money, you connect your own brokerage account." (source) | An AI strategy lab. Describe a strategy in plain English, get exact inspectable rules, and run them on about two decades of data. We are not a broker and not a charting platform. |
| Building a strategy | Plain English to an AI agent called Aurora, in Chat Mode or an autonomous Agent Mode running a plan/think/act loop with parallel subagents — or a visual builder where a strategy is one Action plus a boolean Condition tree. (source) | Plain English, edited by chat. The rules it generates are readable and exportable — no black box, and no language to learn. The rule grammar is deliberately bounded: anything it cannot express, it cannot run. |
| Backtesting | Two modes: OHLC (daily) on all plans, and intraday minute-by-minute on paid plans. Reported metrics are total return, Sharpe, Sortino, max drawdown and a benchmark against SPY. Backtests are metered against a daily research-token budget. (source) | Built in and free to start — the first backtest needs no signup. Daily bars for everyone; intraday timeframes on Pro and above. |
| Markets & data | All US-listed equities, ETFs including leveraged, and major crypto pairs via supported brokerages, with options data for research. NexusTrade does not publish how far back its historical data goes. (source) | US stocks and ETFs on daily bars, with intraday on Pro and the full US universe plus crypto on Max. This is the narrowest coverage on this page — every product here beats us on markets and data depth. |
| Forward testing | Real-time paper trading is available from the free plan upward, and marketplace bots are labelled as forward-deployed and out of sample. No documentation we read describes the rules being locked against edits once a forward test starts. (source) | Freeze a strategy and deploy it. The spec is hashed at deploy and the store rejects edits to it; a daily worker replays the frozen rules on closed candles and appends the result. |
| Public track record | Portfolios are private by default with four share modes; public sharing is free and instant, and public cards show total return, Sharpe, Sortino and max drawdown. A "Show strategy details" toggle lets a creator publish performance while hiding the strategy's conditions. (source) | A public, append-only ledger. Backtest and forward curves sit side by side and are never merged, a revised strategy starts a new record at zero, and strategies that lose stay on the board. |
| Live trading | Yes, through four connected brokerages — Alpaca, TradeStation, Tradier and Public — each supporting paper and live. Orders are staged for review by default, with per-strategy automatic approval available. (source) | None, by design. No broker connections, no order execution, no signals, no price predictions. The exports exist so you can wire that up elsewhere yourself. |
| Export / portability | Export is API- and institution-oriented: JSON and CSV surfaces plus SDK access. In-platform, Fork Strategies makes "an independent copy" with "No ongoing connection to the source". No consumer-facing export of a strategy definition to a portable file is documented. (source) | The full spec as JSON plus a runnable Python file, on every plan including free. It is your strategy, not ours to hold. |
| Free tier | Observer, $0, "no credit card required": up to 2 portfolios, 10 strategies each, unlimited daily backtests, real-time paper trading and both optimizers — but zero Aurora research tokens per day and no monetization. (source) | First backtest with no signup. A free account adds daily-timeframe runs, chat edits, exports and one public deployment — no intraday, no crypto, 10 symbols per run. |

What NexusTrade does better
- Live trading through four connected brokerages, with paper and live modes on each. We do none of this.
- A creator marketplace with copy-trading and revenue share — creators keep 80–95% and can charge up to $999/month. You can be paid for a strategy there; you cannot here.
- Documented walk-forward studies with a train/validation/out-of-sample sequence, plus genetic and systematic-sweep optimizers. Our lab has no optimizer at all.
- They publish their own overfitting warning — "Both optimizer modes can find strategies with incredible backtested returns that won't hold up in live markets" — and rank optimizer leaderboards by validation performance by default.
- An autonomous agent mode that plans, researches and iterates on strategies, plus a REST API, MCP server and Python/TypeScript SDKs.
- Real-time paper trading on the free plan, and options data for research.
The part that is actually different
Every product on this page can produce a backtest, and a backtest is worth having — it kills bad ideas cheaply and shows you how a strategy loses. But a backtest is graded on an exam whose answers already existed when the rules were written. With enough attempts, random noise produces a beautiful one.
Here, a strategy can be frozen: the rules are hashed at deploy and the store refuses to edit them afterwards. From that day it is scored on data that did not exist when it was written, and the record is append-only. Strategies that lose stay on the board.
That is the difference — not better indicators, and not more markets, where we lose to everything on this list. It is a record that means something because it could have gone badly in public. It is our own database with a spec hash, not an audit: what we can honestly claim is frozen, public, and append-only.
Which one you actually want
Pick NexusTrade if: you want plain-English strategy building that ends in a live brokerage order, or you want to monetize strategies through a marketplace.
Pick Chat·Backtest if: you want the frozen rules and their hash published beside the record, where neither can be revised after the fact.
