Create, visualize, backtest, optimize and analyze quantitative strategies across tradable U.S. securities using the latest AI models — or bring strategies you already own, importing Pine Script, thinkScript, NinjaScript and Python with their original semantics preserved. Test them against real market history, rank them across the market, and see the corrections most backtests leave out. Then, if you choose, automate the ones that hold up through a secure connection to a supported brokerage — all in one platform.
