fact, really.
Day trading really requires good knowledge and calculations, as well as consistency, namely consistency in trading, and managing time and money. And this is not easy, because there will be a lot of pressure when day trading, especially in the Future Market. On the other hand, newbies usually can't stand these pressures, especially if the market turns in the opposite direction, panic will occur.
Especially if, as you said earlier, there are many newbies who are just trying to do day trading, without sufficient knowledge or knowledge, so they will complain about the results. Although they say that they are doing this to gain any experience, in fact, to get the experience, we need to learn first and prepare all things that we need for day-trading.
I don't think this is just for beginners. Basically I see the majority saying that day trading is too hard and I have yet to see anyone doing it successfully for a long period of time. This requires a lot of concentration and discipline, and any mistake will result in a loss of funds. Even if a person can do day trading successfully, he will not be able to do it for a long time, it takes too much strength. And in the end, long-term trading will bring better results, and you spend less time.
OP said he has 20 years of experience trading on both markets so can't say he's a newbie but in the end he couldn't beat the market, all of that will happen to seasoned traders as well. Actually day trading is extremely difficult, we face a lot of pressure at the same time and I also think like you no one will be able to succeed. Today's successful traders may have found the right solution to strike the right balance between day trading and long term trading for good results.
