In short
Backtesting software runs a trading rule against historical market data to show how it would have behaved, and the plain-English version works like this: you type the rule the way you would say it, such as "hold NVDA when it closes above the 50-day moving average", and Agenttrading extracts a testable rule, shows it to you before running, then tests it on 20+ years of split- and dividend-adjusted daily data with a 0.1% cost per trade assumed by default. The result is a chart of your strategy against buy-and-hold, the worst drawdown window shaded, every assumption listed, and an honest verdict: HELD UP, MIXED, or UNDERPERFORMED, even when the rule loses to simply holding. Most backtesting software makes you meet it halfway: TrendSpider ($48 to $228 per month) expects indicator fluency, and Portfolio Visualizer is a long configuration form with no explanation of the result. Agenttrading starts at $19 per month, requires no code, and never executes trades: it is educational analysis only, and past performance does not guarantee future results. You test the idea; you decide what it means.

WHAT YOU GET - BACKTESTING SOFTWARE
Backtesting software, run on the bench
The rule is shown before it runs
Agenttrading restates your plain-English idea as an explicit rule card, entry and exit, before the test starts. You always know exactly what is being tested, and you can rephrase if the assistant misread you.
Every assumption printed on the result
Date range, cost per trade (0.1% by default), rule parameters, and dividend treatment appear with every chart. If an assumption would change the answer, you can see it, and adjust it on Pro.
Honest verdicts by design
HELD UP, MIXED, or UNDERPERFORMED, stamped against buy-and-hold. The losing verdict is kept prominent because a backtest that cannot say "this lost" is marketing, not analysis.
Minutes instead of a spreadsheet weekend
The manual version is a data download, a formula sheet, and an evening gone: roughly 4 to 6 hours per idea. The bench runs the same test in minutes and logs what it assumed.
HOW IT WORKS - 4 STEPS
From a sentence to a stamped verdict
Type the rule in plain English
Something like "hold NVDA above the 50-day moving average" is enough. No Pine Script, no logic blocks, no formulas.
Confirm the restated rule
The bench shows the testable rule it extracted, entry and exit, before running anything. Edit or rephrase until it says exactly what you meant.
Watch the backtest draw
The rule runs on 20+ years of split- and dividend-adjusted daily data. Your strategy plots against buy-and-hold with the worst drawdown window shaded.
Read the risks and the verdict
A plain-English risk panel covers drawdown, concentration, regime, and sample size; then the verdict stamps. Historical, not predictive. You decide.

On the same bench
The backtest is half of the bench: the trading strategy tester is where verdicts get stamped, and the historical stock data page explains the adjusted 20-year record every test runs on. If you are paying for a charting power tool today, the TrendSpider alternative comparison is the honest read, and plans from $19 per month cover the rest.
Your next idea deserves a verdict, not a hunch.
Bring a thesis or a ticker. Agenttrading restates the rule, shows the evidence, runs 20+ years of history, and stamps an honest verdict. You decide.
