Scalping in sim/demo is a trading style where the difference between sim or "paper" trading, and live trading, is probably greatest. With live trading, lots of things will eat you up when scalping. Order execution speed. Spread. Commissions. The human element. There are a lot of scalpers out there, yeah. Some make pretty good money. And on paper you are doing good, but that doesn't mean you would do good in live trading, at your present state of skill and training. Especially with a scalping strategy.
Swing trading is where the difference between paper and live trading can be fairly small. The human element is still there, of course. You will make discretionary decisions differently when you are trading with money you had to earn by the sweat of your brow, than with money that doesn't even exist and that you can replenish at will.
Trading can be fun. A bit of a thrill at a nice win, or a twinge of sadness or regret, maybe even anger, at a loss, are natural. The risk adds to the enjoyment. For me, anyway. The trick here is to not let these very natural emotions trigger bad play. Same as in Poker. When you go on a hard tilt, you are going to run out of money pretty quick. You need rules, and you need to follow them and not just wing it. You need to trade like a machine. When X and Y conditions are present, you order according to plan A or maybe B but never C and no freestyling just because you feel M or N will occur without any empirical basis for the prediction. You don't move your stops down to give a position some room. If you placed your stop correctly in the first place, then that is where you want to take your small loss rather than risk a larger one. You don't double down and try to win your money back. Every hand in Poker is a new hand. Every trade is a new trade. If you screwed up, the next play is a chance to get it right this time. Don't use the opportunity to make things worse. There are dozens of common mistakes made by weak players that are seen in both Poker and in trading.
Most important is to develop good risk and money management practices and stick to them rigidly. Live to play another day.
The best thing you can do at this point is buy a few books on the type of trading you want to do. You don't need a whole bookshelf of books on each type of trading you want to do. Most of them just parrot the same advice, and for a good reason. The tried and true methods and practices are proven to give you a fighting chance at making it. When you try to reinvent the wheel you either end up sticking with the wheel, or pushing a different geometrical shape that doesn't really work very well. Just grab the first 3 or 4 you see on an amazon search and you ought to be good to go. Practice what you learn. Immerse yourself in your paper trading, and really walk the walk, really imagine that the money you are betting is real money that you could use for things that you actually need or want, money that you had to bleed and sweat to earn.

TBH, a lot of the books you read will be written by guys who are better at authoring than trading. That's okay. The really good traders probably don't have much time for writing books, but like I said, the standard advice is going to get you off on the right foot. I suggest you don't spend your money on paid courses or webinars or forums or other for profit stuff. Just get a handful of books, and hang out on this, or any other free trading forums, and ask whatever questions your studies bring up and fail to answer.
