Wow, thanks for such a detailed post (although I’m still trying to understand most of it!).
I’ve been only into crypto, especially Bitcoin only so a lot of this is new to me. Also I think you misunderstood what I wanted.
My intention is to be only a dashboard, not performing trades. In crypto I use Blockfolio which is a good tool to keep track of portfolio in all cryptocurrencies, I can connect it to the exchange I use (binance, bitmex) so it will automatically sync all my balances from there so I don’t have to manually update the balances in the app. My question was if it was possible to get your current positions from whichever broker services you are active on using some form of auth keys. So as a user you just have to enter your keys on the app and your latest portfolio from all your brokers will be automatically synced. Since you mentioned about the multi-broker thing you made(Pinakin, nice name btw) I guess this should be possible?
I’m still understanding this, so just waiting to learn more. My skills are with computers and design, so trying to make use of it by solving some problems for people in share market.
