I don't have the time to go into details on this sorry, just search around but I will hit some high point to help you.
Start off with the sim, seriously. Use something Ninja Trader from Mirus it's free and their fills are more difficult than normal, they put you last in line. Don't talk to me about real $$ until you can make money for atleast 1-2 weeks on sim consistently. This isn't a beginner's market, that's for sure.
Find a method of support and resistance you like. Only and I mean only take trades off those lines give or take a a point, in ES. The need to be real close to S/R or you pass.
Learn to trade with some basic price and volume, S/R, it's not critical but it helps for many. When price breaks below one of S/R levels on increasing range of bar or candle, and then on increasing volume and close low it's time to wake up. Then you look for a pullback on lighter volume to what was support and is now resistance and sell and you go in the direction of trend, what you see in the background, lower highs, lower lows shorts only.
You aim for you next S/R line. You start off by aiming for 3-1 reward to risk. Look up positive expectancy and get comfortable with those numbers. Start with 1 contract for every 5-10k you decide. Try the YM or NQ it's costs more on one side, but it's 5 bucks a tick. You can't get hurt too bad. Come up with a plan, put in writing and stick to it.
I am not an affiliate of these guys. I think they have some good material for free. Watch the video on reading price action several times. It's a good video on price, volume, S/R. Their point don't fade moves, you will get killed on days like today.

Lastly if you see something that fits your plan but the stop is too $$$ pass. Yes pass. Risk management is everything in this business. Just ask the f-ups that are blowing up right now on wall street.

I hope it helps.
Post Edit: I realize this doesn't answer your exact question, but these are all inferences to risk management. P.S. 4% is too much stay to 2% starting out.
