Barchart is a data-first platform spanning technical analysis, market flow, news and ETFs.
1. Advanced heat maps
Beyond simple change-based maps, you can customize heat maps that fold in volume, momentum and RSI — useful when you want finer conditions than Finviz's map.
2. Technical tools
It organizes per-stock technical indicators and signals — helpful for chart-driven traders.
3. Note
Dense with information, it suits intermediate+ users. If you're new, get a feel with the Finviz heat map first, then move to Barchart.
