Day trading should be done when volatility is high.
In a calm wave, this is the stage where you are preparing for a short-term or longer transaction.
I think there is something wrong with the logic that we should refrain from day trading just because there is a strangely large decline.
When trading as the price rises, you should proceed with day tading while reducing the proportion of your investment.
Otherwise, if you continue to do day trading with the same proportion or increasing the proportion, you will end up buying at the highest point.
So, I think we can say that it is better not to do day trading.
No matter what investment period you trade with, you must decide on a trading strategy appropriate for that investment period: investment proportions, trading method, and profit realization method.
If you are not earning consistent profits through day trading, you need to check the trading strategy you have created.
The idea that chart analysis is a trading strategy is a misconception.
You must create a trading strategy and trade it.
