Figure out what/how you want to trade. Daytrade? Swingtrade? Investing? Forex? Stocks? Futures? Crypto? Options? Indicators? Support/Resistance? Fundamentals? Go to youtube and search for things like "daytrading", "swingtrading", "support and resistance trading", etc... https://www.youtube.com/results?search_query=daytrading https://www.youtube.com/results?search_query=swing+trading https://www.youtube.com/results?search_query=support+and+resistance+trading+strategy Watch small portions of several videos to see if anything looks interesting to you. After you find something that interests you then watch more videos all related to the same style of trading. What works for someone might not for the next person so only YOU can find what works for YOU. Some say indicators don't work but one of the best daytraders I've seen uses MAs and makes millions yearly for many years. I've also seen some very good supply/demand traders.
CME has great content. It's surprising how many "traders" do not even know the basics around exchange rules, order types and qualifiers and contract specs.
If you look at the old P/L threads, there were some pretty amazing numbers. Some folks were well into the 60's, and they were hugely profitable traders. But some are at 70% and they couldn't trade their way out of a wet paper bag.
I think you misunderstood: when I said I first started learning about futures in the 90s, I didn't mean that I kept it up for the past 30 years. I gave it up not long after I started because I was a naive, broke 26 year old college student thinking I could get rich overnight trading futures. Now that I am more mature and level headed, I am much more aware of the risks and complexities involved.
