Yes, they can. If you only know the very basics like how to buy and sell what red and green candles means etc then you can. You can use a grid trading strategy. In this strategy, we will use a trading bot that will place buy and sell order automatic and it will buy low and sell high. You just needs to set the price range. You can set higher price range and do your other activity. That bot will execute trade with the parameter you set.
I understand what you mean, if I conclude the trade you mentioned is trading for beginners who trade without a thorough analysis,
so trades are executed based on rising and falling charts at that time. when the candle is red you will buy it and when the candle is green you will sell it.
yes that's fine, but what time frame to use? The small time frame is not suitable for beginners, as it will only make him lose more than profit.
