What a great day!
You've installed Autoview and are now looking to setup an exchange. We are going to use 1Broker as the example here as that is the free, and most popular exchange with Autoview. It is also the best place for learning how this all works, and getting comfortable with it.
The first thing you're going to want to do, is login to 1Broker and navigate to your Access & API Management, you can find this by clicking the settings button . You are then going to click the Generate API Token button. You will be prompted to enter an IP Address Restriction, this can be left as is, or you can use a site like ipify to determine your ip and restrict all communication via this API token to your IP address. This can be changed at anytime.
Copy your new API token and navigate your way to your Autoview Settings page than select 1Broker on the left hand side under the Exchanges section.
There are 3 sections on the 1Broker settings page, the first being an account field. This should be left as an asterisk(*) unless you plan on running your strategy for other people. In the event you change this, you will need to use the a= syntax in order for Autoview to initiate any trades.
The second is where you'll paste the API Token you just created on 1broker. Be careful if copying and pasting as sometimes there is an extra blank space at the end of the API Key when you paste it. To make sure all will work properly, check for this.
Your overall settings page should now look like this:
Congratulations, you're now ready to move over to TradingView, write some alert syntax in your alert message and watch your trades open/close themselves.
