as long as we can be disciplined in managing our trades then even day trading can still generate profits and keep losses minimal. the important thing is that we have made a target percentage in profit and loss. so with that we have locked the stoploss target and takeprofit target. and we must obey and be disciplined with the plans/management that have been made. I see many people lose a lot from day trading is because they are wrong in implementing the trading strategy. maybe they are used to long and medium term trading and they apply that strategy instead in day trading. then it is very clear that it will only bring losses and even confuse the trader's mentality. Each type of trade has a different type of strategy. so we need to know exactly what kind of trade we are going to do. such a DCA strategy would be well suited for the long and medium term.
Not getting out of your system and method is a hard thing for newbies, not so much for veterans. There are too many people who see how you should become an investor and can get rich, and instead of following this route, they end up with doing even worse, because they end up changing their method right in the middle when things are going bad.
Most common example is, there are some people who saw it go from 68k to 40k, and bought bitcoin because it dropped, then it dropped another 50% on top of that, and they sold, that’s a mistake. You should have bought more, and waited long term to make a profit, this is known and if you changed your mind, you made a mistake.
