A working MVP social media site for stock traders using Bubble

Request details I found a template from bubble to cut the time down, so I just need to customize it to fit what I am trying to do. Connect with brokerage accounts to pull a user performance history in terms of percentages only, not their dollar amount. So for instance, I can select or enter a time frame like the last 5 years, and be able to see how well he did each of those years on a chat (+50%,+43%,-2%,+60%,+26% ... again not their dollar amount) ... I found Yodlee as a great service to be able to do this. So dealing with this, when onboarding, the users of the platform will need to be prompted to add their brokerage account now or later in their dashboard. I will also need to pull the trades that they do and also, as a user makes a trade, it will need to be submitted as a post from them I also want to make it so that a user is charged $15/month to gain access to use the site or pay for a whole year for $10/month I will outline details of what needs to be changed/edited and I am open to expert opinion Deliverables Complete onboarding to connect with a brokerage account Complete user profile page to display their trades and performance history on one end, and their posts on the other (there would need to be a button to allow users to switch) Complete flow of user trades becoming posts and recording posts
