The charts below for Bitcoin, Ethereum, Ripple, and more are generated live from Tech Trader, a fully autonomous trading system originally for the stock market. "Bot" labels signal potential bottoms based on volume capitulation. Those on the 30-min chart are more short-term while those on the daily chart are extremely rare and usually longer-term but less immediate of a bounce.
