At a glance
TrendSpider and Horizon both let you build a strategy without code, and they part ways on what happens after the backtest. On TrendSpider the strategy lives on the chart, and a Strategy Bot sends its signals out by webhook to an order router such as SignalStack or TradersPost, which places the order at your broker. On Horizon the strategy is written from a plain-English description, backtested and run in one place, in your broker account, with no router in the chain.
