Hi there,
I read the project description and it seems pretty straightforward. Please share more details about the project such as:
+ Do you want to users sign up on the app and each their on portfolio?
+ Or is this ore like an data scraper app which runs 24/7 and gathers information of all available stocks?
+ Also which Stock broker API do you want to use?
I am full stack MERN Developer (MongoDB, ExpressJS, ReactJS and NodeJS) and I estimated one week to two weeks will be enough for this project depending on what features you need.
Thanks and looking forward to work with you,
Babak
