It is not good or bad in my opinion. Price Levels are important barriers. The price could just break through it, it is a possibility always.
But if you know the important levels where you want to take action, and what action you want to take, then you can have some edge.
Take for example, if I wanted to short EURUSD at 1100 during London session, then it matters what will be the price reaction at that level. It is not good or bad.
Based on how you look at support & resistance levels, these can be area of interest where you can enter or exit your position.
