Supports and Resistances are more of an Art than a Science. There are plenty of methods to find and draw them. I'd like to warn that S&R aren't ultra sharp, precise. Usually it's more of an area than a thin line. Also, it can breaks. It's not 100% sure. And nothing's 100% sure out there. But I've got one advice. Search for them in a higher time frame. If you trade Daily, look for weekly supports and resistance.
