Backtest Everything.
Quant, our coding agent, is built into Vela, our next-generation charting platform, and proves every strategy it builds against history in the same window it was built in: next-gen, bias-free, and refinable in conversation.
Free to start. No credit card required.
From idea to evidence.
The old loop was fragmented: build in one tool, restructure the code by hand, test somewhere else. On LuxAlgo it's one window: describe, chart, backtest, refine, then save, and the next refinement picks up exactly where this one ended.

Read the whole report.
A single headline number isn't a verdict. The report shows you quality.
Net profit, profit factor, win rate, average P&L, and closed trades, split by long and short, so you see whether a strategy only works in one direction. Daily P&L, weekday performance, and trade distribution get their own visual breakdowns, with Monte Carlo when you want to go deeper. Strong strategies show you where they're strong; weak ones show you exactly what to fix next.
Research that compounds.
Strategy development is never one attempt. Save every strategy, return to it from the sidebar, and build variations without screenshots, pasted code, or scattered notes. Your research becomes a collection, and the ideas that showed promise stay one click from their next refinement.

See which prop firm challenges it passes.
The Prop Firms tab replays your backtest's closed trades through every challenge in our prop firm directory and lists the ones it would pass, firm by firm, then the near misses and what each is missing. Stress-test a pass to see whether it held up or came down to luck.

Frequent questions.
Yes. Any strategy Quant builds can be backtested without leaving the conversation. The full performance report returns in the same window you built it in.
