Scalping, trading on short-term time frames, can be a profitable but also risky strategy. People who successfully scalp usually have a high level of experience, strategic thinking and quick reactions. However, trading on longer time frames requires patience and analytical skills. In general, here and now - this is scalping; basically, of course, everyone uses this strategy on futures.
Scalping is not only a short-term trading strategy but emphatically the shortest-term trading strategy that traders without very good scalping skills and patience can not excel in. This is actually beyond merely gaining a high level of experience but being able to know the scalping code, have the will, energy and time for it, and also have your own scalping plan and sticking to this plan. As easy as these points could be, many have not been able to fulfil them, and some people who fulfilled them for a while later renege from them. To be candid, scalping is not easy, and this is why people are avoiding it, it's so demanding, and the shorter the term of the trading strategy you are using, the riskier and more stressful it will be. That is how scalping is, but with the right level of mindset and determination towards it, I believe the trader will be successful.
And guess what? The money that could be made in scalping is more than any other trading strategy you can think of, which is why successful scapers are the richest traders in the world. They enter the market many times in a day and get to do this with big risks/lots and opt out pretty fast, repeating the process multiple times in a day for more success to be made. So, this is no joke, they are rich because they could go through the stress which I believe is worth it.
You also have a point with the short timeframe by scalpers, but in my scalping experience, it's beyond that. Although short timeframes are still being used, yet the most successful scalpers do scalp the trend of the market mostly. For this, they get to first analyze the larger charts to know the trend then use the lower charts for the regular scalping towards the main trend of the market. In this light, multiple timeframes are the best for it in my experience.
