You need to exercise extreme caution when trading the news, the few that are successful doing this still use TA heavily in their strategy and it is not difficult to understand why, even if you could tell accurately whether a news will affect the market and the direction the market will take, you have no way to know the magnitude and the duration of such movement, in order to get an idea of that you need TA, which explains why many traders that use TA do not bother with the news, as the price sooner or later will reflect the effects of those news on the markets anyway.
That's why it's very important to have a fundamental analysis (FA) while making your technical analysis (TA). FA is a very important factor that could possibly have an effect on the market price. Like what happened to this event now, the war between Russia and Ukraine was shaking the price of Bitcoin, you can't draw a conclusion for sure if you only have TA.
that's why the winner in this matter are the Holders because the longer they Hold is the safer their funds are.
lets not take advantage of the possibilities of bumping and pumping because none of these are possible to come now.
But sometimes, it's an unpredictable movement of Bitcoin even there's a world event it doesn't hurt too much the price. For example the same as when the pandemic hit, it was affected by the start but after a week it was resisted and increased the price back.
Because the investors now knows how the market will move and what can be the possible outcome of each cases, so even this war? won't make this market dumped like what happened in pandemic time.
