Most traders end up juggling a charting site, a spreadsheet journal and a separate backtester, and none of them talk to each other. TraderPier puts it all in one place for US stocks and ETFs. You can replay a past trading day bar by bar to practice your setups, import your trades from your broker and replay each one to see what really happened, then test an idea on past data before you trade it. Spyglass, the AI quant on your desk, works inside all of it. Because it can see your chart and your journal, you can ask it what a stock has been doing, why your last few trades lost, or to turn a setup you keep trading into an indicator or strategy and backtest it. When something holds up, you can run it on paper for free, or live through your own broker on the Quant plan. The free plan has no time limit and needs no card, and Spyglass comes with Trader and Quant.
