Is it a hunch or a real edge?
Stop Trading on Gut.
Start Trading on Evidence.
Describe your strategy in plain English, upload your trades, or drop in a chart — and get a statistically validated backtest in minutes. No code. No subscription. Just proof.

If you've ever thought any of these, you're in the right place
- “I have a strategy idea but no way to test it without coding
- “I backtested something, it looked great — then failed in live trading
- “I follow traders online but never actually verify their setups
- “I've been trading for years but can't tell which of my patterns have real edge
- “I'm paying for a platform I barely use
Most traders are flying blind — acting on instinct, copying strategies from social media, and paying for tools they never master. BackTestLM was built for the trader who wants to know for certain.
Built Different. On Purpose.
Everything you need to turn trading ideas into evidence — and conviction into confidence.

Why BackTestLM is Different
Traditional platforms are complex, locked behind subscriptions, and designed for developers who can code. BackTestLM was built for traders — not engineers. Plain English. One page. Results in seconds.
| Capability | BackTestLM | Traditional Platforms |
|---|---|---|
| Strategy creation | Plain English, chart upload, or trade history — Zero Code | Coding or rigid visual builders |
| Data inputs | Price + macro events + corporate calendar + social sentiment | Mostly price-based indicators |
| Your own trade history | Upload trades → grid search → find what would have worked better | Not supported |
| AI improvement loop | Scores, explains, suggests, and applies improvements automatically | Manual trial-and-error — static results |
| Screener + Multi-symbol | Screen any ticker universe; aggregated results across symbols | Single symbol or limited scope |
| Validation + Optimization | Blind Data, Monte Carlo, Walk-Forward, Grid Search — built in | Partial or manual |
| Workflow | All-in-one: idea → test → validate → optimize | Multiple disconnected tools and steps |
| Pricing | Pay-per-use — no subscription required | Monthly or annual subscriptions |
