yes my dear I actually do believe support and resistance both are very important of technical analysis and i think this is the first step of learning about the technical analysis, we can draw a resistance using top two to three point and can draw support using two to three bottom point of the price action. Support and resistance levels from my point of view are one of the topmost technical analyses that can result in a high profit and there are some high volatile currencies that test this level is on a consistent basis so you can make a huge profit on that currencies pairs like pound pairs but you must know how to analyse the right support and resistance also
