Trend is up open weekly chart

I do not understand why some people are going LONG when they know the market is in downtrend.
The main concern is the WAR in which now the US is also involved and it’s not going to pump soon, so try to understand the trend and don’t go against the trend.
The market will be in downtrend.It will fluctuate but don’t be panic.
