To trade using AlgoCloud you first need to connect it to your broker from the list of supported ones. You can have more than one connected brokers, and you can connect both demo (paper) and live (real money) accounts of your brokers.
AlgoCloud then allows you to deploy your algo strategy on the cloud - where it will be running autonomously - and it will send orders to buy/sell through your broker connection directly to your broker.
So AlgoCloud acts as a classic trading platform, sending orders through the broker-provided API, and you will see the trades directly on your broker account.
