You need some form of membership/user profiles, which in itself is fairly easy, BUT to then have a reactive feed that determines what stocks they own, and their existing value is complicated.
That’s all before you look at the the ability to actually trade/buy/sell/checkout within the site.
Maybe we can so it in 2 parts.
At least i want people to be able to buy the shares.
And for the admin, maybe there is another option that i can use on a subdomain for excample.
I don’t mind to put the information manually in the admin.
But the most important thing is to sell the shares.
And i have the certificates to sell the shares and they will be limited from time to time.
I’m not an expert in that space but I would have thought that buying and selling shares comes with some serious compliance expectation and regulations which a stock website would not stand up to as it is.
I really do t think you will find anything like this on a stock marketplace and even built properly you would be looking at thousand of $ before you start costing sufficient security and hosting
