Our dev team recently launched CoveTrader at https://trader.covemarkets.com/. Using our extensive experience from traditional financial markets, we connect to many crypto exchanges (Coinbase, Kraken, Bitstamp, etc.) and show aggregated order books, trade lists, and analytics in both real-time and historical formats. We currently support BTC, ETH, LTC, BCH, ETC, EOS, and XRP, but are adding more. It's currently just analytics, but we'll be adding order sending in Q2. Feedback and feature requests are welcome and can be sent to email@example.com.
