BacktestLM vs. Trade Ideas
Trade Ideas is a real-time stock screener and alert platform with an AI assistant (Holly) for generating trade ideas. BacktestLM is a strategy backtesting and validation platform with screening capabilities. The two tools solve different problems.

When to use Trade Ideas
- You are an active day trader who needs real-time momentum scanning and tape reading.
- You want AI-generated trade ideas surfaced in real time via Holly AI.
- You trade primarily U.S. equities intraday.
- You want real-time alerts for specific technical patterns.
When to use BacktestLM
- You want to statistically validate whether a strategy or screening setup has a real historical edge.
- You need walk-forward optimization and Monte Carlo simulation to confirm robustness.
- You trade multiple asset classes (stocks, crypto, forex) or timeframes beyond intraday.
- You want to test a strategy across a broad universe of tickers simultaneously.
- You want AI to screen for your strategy's current setups after validating it historically.
The validation gap
Trade Ideas generates trade ideas — it does not validate them. Holly AI surfaces setups based on its model, but traders cannot easily verify the historical statistical edge behind those setups or stress-test them against different market conditions.
BacktestLM fills this gap. You can take a setup pattern (from any source) and validate it: how did this setup perform over 10 years? What is the walk-forward Sharpe ratio? What is the 95th-percentile drawdown under Monte Carlo? These answers help traders decide which ideas to act on with real size.
