On top of algo trading, I also trade is using external signals I get from services such as Flowalgo and BlackBox. I run my analysis on the alerts I get from these services on my local machine (laptop), and if any of them matches my criteria, I place an order. Can QuantConnect able to receive such alerts via some mechanism (external webhooks?) if I'm running in the Cloud? Additionally, it is not clear if I can run QuantConnect locally (on my laptop). If yes, can it receive alerts via the command line and execute them?
