The Strategy Tester runs the Pine script itself on real data, not a rewrite of it. Orders fill at the next bar's open, the script never sees future data, and every fill pays 5 bps commission and 2.5 bps slippage per side by default.
Each run is split into an in-sample and an out-of-sample period, stated as dates. The held-out part gets a verdict: survived, decayed, did not survive, or too few trades to judge. Drawdown analytics and the full list of trades come with every run.
The optimiser fits a script's inputs on the past, judges them on data it never saw, and compares the winner against the best of the same number of random tries.
The data and its adjustments, the universe and its survivorship bias, the fill rules and the verdict's thresholds are written out in Data and methodology.
For traders of US stocks, ETFs and NQ or ES futures who want trading costs and a held-out test in every backtest by default, yes. LuxAlgo covers more markets and has a free plan, so it fits traders who need those.
Yes. Alpha Charts' Pine Copilot and LuxAlgo's Quant both write Pine Script from a description and backtest it. On Alpha Charts every run is also split into an in-sample and an out-of-sample period, with costs charged, without setting anything up.
Yes. Paste the Pine Script v6 strategy as TradingView has it and the Strategy Tester runs that script on real market data. Alpha Charts uses its own Pine runtime, so a script can occasionally behave differently than on TradingView.
No. It shows whether the strategy held up on data it was not tuned on, which is a better test than the fitted period alone. Live results still depend on the market, the number of trades, the costs you really pay and how often the strategy was re-tuned.
LuxAlgo for crypto and forex, and for futures beyond NQ and ES. Alpha Charts backtests US stocks and ETFs, plus NQ, MNQ, ES and MES futures for signed-in accounts.
