Adrian Reid says TradingView's backtesting is too basic for serious traders. PineScript is harder to learn than Easy Language or AFL, and the platform only handles single-instrument systems. He recommends switching to AmiBroker, RealTest, or MultiCharts for backtesting instead.

Now TradingView backtesting is again, pretty rudimentary. TradingView is built for discretionary technical analysis. It's a great charting interface. It's got great data feeds, access to all of the markets that you'll possibly need and lots of indicators you can overlay on your charts, great chart annotations and ability to edit, manage and manipulate your charts. But backtesting is again, pretty much a dog. If you wanna backtest in TradingView, you've gotta learn PineScript, which is nowhere near as easy as Easy Language or AFL, and certainly nowhere near as easy as RealTest. And you're also limited to single instrument systems. So I would say the backtesting in TradingView is a second thought at best. And so if you wanna move from discretionary technical analysis to systematic trading, I would say just get off TradingView, learn some proper backtesting software, Go straight for Amibroker, RealTest, or maybe MultiCharts, and just give TradingView a miss. Keep that for your discretionary technical analysis.
