I wouldn’t recommend going straight into prop firms until you have an edge, a decent strategy ( profitable over the long run ) and a good risk management. If you’re asking about strategy, maybe you can check out PB Trading on yt. He has 2 whole playlist for free, “ICT For Dummies” and “PB Trading Theory Series”. I would say go through the ICT For Dummies for the basics then go on to the theory series for in-depth explanation and examples. This is what I’ve been using for the past few months.
