Alpaca automated trading from alerts

Alpaca publishes a trading API that places orders in your Alpaca account, paper or live, with an API key. Nyria reads your alerts from TradingView, TrendSpider, a webhook, or a Discord server or Telegram chat you run, and places each as an order through that API. Alpaca trades stocks and ETFs in whole shares, options up to 4 legs and crypto spot. You generate a key in Alpaca's dashboard and paste it into Nyria. Nyria Paper is a free first test.
