Alpaca is a good algo-trading platform that provides easy and cheap access to trading APIs. Although not frequently used, but the web UI plays a key role in customer satisfactory. One critical issue I observe is: the “Login” button on the homepage do not check my cookie, and hence I have to login every time if I reopen the webpage. The two-step login verification makes this process even more annoying.
One workaround is using the “Sign up” button instead of “Login” button. The “Sign up” button does remember my cookie. I’m not sure if this is an intended behavior or a bug that needs to be fixed.
