At a glance
Capitalise.ai pioneered plain-English automation for traders at its partner brokers, mostly in forex and CFDs. Since Kraken bought it, the standalone product is being folded into Kraken Pro. Horizon covers US stocks, ETFs and crypto through the broker you already use, backtests every strategy, lets you run it on paper first, and adds creators' strategies you can copy.
