Stock trading - intraday trading and indicators

Hi guys. I am begginer trader and I come from Europe and I trading on IQoption. I go through Baby pips school and it learned me a lot. But you know that is the maximum they can teach and we need some extra education and we need to share ideas to improve our trading skills. So last two months I traded opening of USA stock market with my strategy. It was based on pre market moves and on two indicators from tradingview public library. So I want to ask you, traders with the experience, what tehnical indicators to use for intraday strategy and what is the best news portal to catch main news about companies which we are trading ( like Devon, Alcoa, Cronos group and etc). Thanks to everyone who will reply on this!
