Been looking for a free API which could provides real time stocks quotations. Number of request is less than 100 per day for top 10 QQQ stocks. Looking for last price and Daily VWAP. Looks like Google finance API got discontinued. Can't find official documentation about Yahoo finance ? Polygon's free plan doesn't includes real time quotations ... Taapi.io is mainly for cryptocurrencies.
Interactive brokers API is a separate download to IB TWS. Free for customers. VWAP will be for you to calculate on any api.
Alright, thanks. I'll give it a look as I am still a customer with them. VWAP isn't calculated on a tick, print basis ? Well .. I'd need the volume per prices.
I've heard that IB will classify the client as professional trader if he uses IB API. Is that the case?
No, that is not correct. Some of IB's terminology is confusing: for US customers they offer the "IBKR Lite" and "IBKR Pro" account. Lite does not give access to the API, Pro does. But this word Pro does not imply that they consider you a professional trader.
That is a bit of a complicated story, as you can read here: https://www.marketdata.app/how-to-use-the-yahoo-finance-api/
On IBKR TWS I Have a Real Time VWAP quote (accurate) TOO for EVERY stock so it should be able to be pulled through the API. So you would have price and calculated vWap for free. If you want Daily vWap you only grab the IBKR vWap at 4pm Eastern Time at the bell.
