Kasiel vs Finviz
Best free stock screener — heatmaps, filters, technical pattern scanning
TL;DR
Finviz is the best free stock screener on the internet — fast, comprehensive, and the heatmap alone is worth opening daily. But Finviz is a screening tool, not an analysis tool: it surfaces tickers matching your filters, it doesn't tell you whether to actually buy them. Kasiel picks up where Finviz leaves off — run Finviz to find candidates, run Kasiel to decide which ones make the cut.
