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.
