Accesing Pre-Market Data and updating the Universe with it just before the Market Opens

Back

Hi!

I would love to be able to use pre-market data just before the market opens or right when it does. I have been searching the forums, and in some posts, people said it was possible, but in other ones, they said that the universe updates at 00:00, and at 06:00. So I ended up more confused than at the beginning. I am using Python. 

  • Anyone knows when the universe updates, or if it updates every time?
  • And how do I access pre-market data?
  • And as an addition, is it possible to research for news in live trading?
Thanks in advance!

Hi Pablo,

  • Universe updates every day based on end-of-day data, so it updates after the market closes. Read more about the timing here.
  • Regarding pre-market data, you might find Jared's old post helpful.
  • Unfortunately, we currently do not support news data yet, but we are adding Tiingo news data soon!
