I would like to build something like "tradingview.com" for a private broker
I've been crawling the entire internet with the quest of "Finding something that will actually fit that requirement"
I've learned a lot, trust me I knew nothing about stocks / exchanges / brokers / investment, now I have a very poor idea of everything however I just don't get to see the right path to get data as a broker as most of the APIs I've found are data for the investors not for the brokers.
Tradingview offers several brokers to buy/sell whatever investors needs however, as a broker, where do I crawl data from?
Do I have to call exchanges in order to get a license to get real-time data in order to create my financial instruments or should I just go to this article and start doing PoCs of API consumption and display some simple linear/area charts with highcharts should I go to this other website which seems to be a good place to find APIs but it does not look like what I need, also highcharts stock charts seem to be a good but there's several other websites that do offer some crazy charts like the ones available at tradingview.
Basically what I need is some guidance of how to get data as a broker from exchanges in order to build private financial tools available for this broker's clients.
Do not limit the budget let it hit the fan
I could scrape the hell out tradingview using websockets but I guess there might be a better way to get that data like a membership, agreement, or whatever is required from exchanges
