Been scalping over 25 years, no sense any more for my style to do 200-300 trades a day when I moved from manual to automation, always a give up. If I was to do over again, never of gone into scalping cause of the hours to learn how to do it, I gave up so much of life in general. Must eventually build up account to be able to do volume, concentrate on risk management as it is only entity you can control much of the time.
I learned how to do long term first in stocks, thought it was much easier, commodities were extremely tougher to learn without knowing programming, leverage alone can mess with one's mind. Took me seven years to get profitable and another seven years to understand well. It has made my longer term much better based on learning when not to take trades and turning many "breakeven plus lunch" trades into making little more. I cannot say for others nor use general statements of what works best or works worst, too many have closed minded thoughts of what one should not do. I have always worked towards of what masses cannot do, so that if I can't beat huge traders, can take profits from retail. So studying entries/exits of retail, to me made sense to learn.
I started in 1978, long term, this started as a hobby and most of life been retail cept last twelve years ramped up. Earned three degrees in Business, Science and Masters in Management, only used for personal uses as more physical type of employment made more sense of being paid to "work out", plus do not like working with people. Having Asperger's may have helped a good deal seeing pattern's that most can't initially see or lack of patterns. In my 20's my IQ was very high, but I often think now it was stumbling block as I relied too often of what made sense and markets are almost always illogical. I still manually trade to test out new systems, but I trade more of fear of losing knowledge as most new systems are rehashing of current models. You just learn eventually what works for you.
I would never recommend to others to scalp, over long haul more to be made long term/swing trading/hedged, reward to risk if far greater and risk tightly controlled whereas scalping R:R is in my case often inverse and show biggest losses when volatility is too high. My style is more of a grinder in controlled price action, so sweep up easier price action instead of trading wild and wolly.
Best to sim and triple three times before going live, best to know the answers before the question. Good luck to your new endeavor.
