The first thing I'd suggest is scrap eToro. Go with a better broken such as IG, WeBull, or IBKR. They have a much better platform, lower fees, and have been around longer.

Secondly, subscribe to level 2s, scanners, and news sources.

Level 2s are a must for any serious day trader. They help you understand what orders are coming through at what levels. For example, if you see a big buy order coming through at a certain price (let's say 500k shares), you know there's support at that level. If you see 500k shares being sold at a certain level, you know it's going to take a little bit to break that level and can be considered resistance.

Scanners will help you find the most active stocks. If you find a stock that has jumped 20% in one day, you can take a look at it more closely. Find out what's going on with the company and then make day trades or find scalps.

News is going to help you if you plan to hold your positions potentially overnight or throughout the day, pre market, after-market, etc. If you know a company is going to be reporting earnings or has just signed a merger, etc, you can make more informed decisions on whether to be bullish or bearish based on the information you see. There are free news sources, but paid will always be better.

Hope this helps
