You must start with the basic courses. Watch them a couple of times, Read Andrew's book too.
After that move to the strategy which clicks to you, or the strategies of the moderator you feel you understand the most. Something you want to try.. For me personally, I remember from the first days, I was drawn to Airman's trading style, Although I just joined BBT, I tended to watch his videos and webinars and join his reviews on Monday and Thursday, I didn't understand the price action but I felt that I am gaining knowledge which makes sense to me, this is where my intuition was leading me.
You need to practice, Just watching videos will not help as you need first to get screen time, understand the platform and how it works and than move to the strategy. Spend a month to find out which layout you are comfortable, go through DAS menus, try everything, don't rush to trade. Click buttons and watch price action.
Once you have found time frames you will be looking at, you like dark or light charts, you know how to use the montage and your eyes are comfortable with the speed of T&S and L2, move to the strategies.. I started with ABCD, than reversals. Note down the rules of the strategy you are going to trade and start from there. Trade the strategy for a month or more, one strategy at the time and keep stats on your performance. Take screenshots on all your trades and review them after the market close. Track your win rate by strategy and your Rs. It will start showing which is your style. Slowly you will start seeing better results with one strategy and some of the strategies will not work for you. But you have to do this for at least a month per strategy. There is no recipe which can tell you which strategy to chose as we are all different and if something works for someone, doesn't work for the other. You find yourself by practicing. It is a process and takes long. Set the right expectations. I am 2 years in trading and just now consider transitioning live. Yes I traded 2 years in a simulator every day for 5-6 hours until I found some consistency with two strategies thanks to Aiman. I still struggle when market cycle changes and have a long way to go to master my process and psychology. But I know I can do it. This is a new skill and takes time. Don't rush the process. Repetition is the mother of all skills. Good Luck! I You will do it!
