CapitalSignal
Free stock research tools built by a 16-year-old
CapitalSignal とは？
I'm 16 and spent months building CapitalSignal from scratc, with zero prior coding experience. It's a free stock research platform with live prices, candlestick charts, AI summaries, DCF calculator, options flow, paper trading, watchlists, and 40+ tools. No signup. No ads. No paywall. Just tools that work. Built because I couldn't find a free platform that gave real analysis in one place. So I made it.
