It really depends on the trading strategies used by the individual
maybe I really agree, that everyone's trading strategy will certainly be different from one another and is normal. because the habits that have been carried out in trading will certainly lead people to do it continuously, apart from the fact that the situation that is built is no longer suitable and experiences disadvantage so that it changes methods and days that may be adapted to new ones, although of course it is very risky to make those changes.
for me its good to trade on weekends because I feel not huge volatile swing so its possible to make 1 or 2% by doing day trading on those days with less risk compared to high swing days. Also I am not really used to trade on major event basis but many people succeeded on those occasions if the find the things before it happens.
some may indeed trade in accordance with major events that have occurred before, and it certainly returns to a habit that will make that person will do it, maybe even people do not associate major events with trading but instead apply it to the day when they will trade.
