I just used it for the first time and here is what happened. I started a portfolio called Test1. I added some strategies. I clicked on Trade Simulated. And viola. No warning. No explanation. I suddenly found myself subscribed to every strategy that I put in the test portfolio. This is not at all what anyone expects to happen. How do I know that? Because for months system developers have been flooded with thousands of “subscribed” then immediately “unsubscribed” messages. Please fix the UI, it is totally misleading.
