Some people said just close your eyes and buy stocks. A few years later, you can retire very rich with very little effort. Anyway, do your homework.
Two reasons: 1. Due to the high volume of trades, the learning curve is a lot quicker with scalping than daytrading or swing trading. You can statistically see very quickly what works and what doesn't. Whereas daytrading or swing trading it takes a lot longer to build up that requisite sample size of a particular set up in order to actually analyze it. 2. It smooths out your equity curve. Doing 200 scalp trades a week with a 60% win rate at the standard 1 to 1 risk reward, yields a smoother equity curve than ten big day trades with a 40% win rate but better risk reward.
Scalping is preferred because it offers frequent opportunities for profit, allows quick action in volatile markets, and requires less exposure to risk. Traders enjoy the fast-paced nature and potential for consistent small gains.
I think that first of all, such traders want to be able to earn every day and withdraw their profits every day (but it is not a fact that many succeed ). Also, with such trading, the risks of unexpected price behavior at night and the associated possible losses (the occurrence of gaps against your positions) are minimized, as well as reducing your costs on negative swaps for transferring transactions to the next business day.
Just curious. What is scalping in your context, and how tiny are the profits you're generating on average per contract? If you can't approximate an average (understandable), then how about a range?
