These settings hold up. The best of 100 random tries would score 0.94 — this one scored 1.15, and it held up in 3 of the 3 slices it never saw. The settings either side score 1.10 and 1.09, so this is a plateau rather than one lucky cell.

FAQ
Questions, answered
Alpha Charts is an AI Pine Script assistant and strategy tester. Describe a trade idea in plain words and the AI writes the Pine v6 script, then the Strategy Tester runs that exact script on real data with commission and slippage charged and checks it on data it never saw. You can also screen US stocks with your script and get alerts on your own conditions. It is made by Coastline Digital sp. z o.o. in Warsaw.
Real data for about 1,400 US stocks and the major index ETFs (SPY, QQQ, IWM, DIA, VOO, VTI), on timeframes from one minute to monthly, with commission and slippage charged on every fill. Daily history starts in 2016. The tester runs your script itself, so the trades on the chart are the script's own.
The three indicators run on any market TradingView charts, on any timeframe. The Strategy Tester covers about 1,400 US stocks and the major index ETFs, on timeframes from one minute to monthly, and the screener runs across the same stocks. Crypto, forex and options are not backtested.
Yes. Paste any Pine script and run the audit, the backtest, the optimiser and the screener on it, the same as one the AI wrote.
No. The indicators work out of the box, and the AI writes the Pine when you want your own idea on the chart. You describe, it builds, you test.
No. The indicators run on any TradingView plan, including Free. Alert limits follow your TradingView plan.
Add your TradingView username in your account. We grant invite-only access to the three indicators, usually within minutes and always within 24 hours, and they appear under Indicators → Invite-only scripts.
Yes. Monthly and annual plans cancel in one click, and every plan comes with 30 days money back from its first payment.
