I believe there is a huge difference between scalping and swing trading, in swing you can build up necessary skills to achieve consistent profits, often times profits are far greater than risk.
Scalping to be consistent and make better than decent living, better be well seasoned trader, intense focus, leasing or owning a seat at exchange to get lowest fees. I have no clue what forex strategies, there was no forex in 1978 when I started trading long term stocks, only scalping was done in the future pits. In automation there is set risk, but manually seldom used a protective stops and all trades risk has been far greater than profits. You get so good at reading charts, understanding price rotation, cycles, slopes, it is a 6th sense of when to the plug on bad trade. Trading on a laptop, can be anywhere, make in one hour more than most people make in a year. I never thought any of this could happen 43 years ago. But one gives up much to become well versed in scalping, am at a Starbucks, girlfriend 1880 miles away. Used computers so much required carpal tunnel surgeries and doing rehab now.
I often think much of what is copied and posted on ET is done by writers of the markets and people who don't physically trade.
Happy Thanksgiving all.
