It's fairly easy
OK, now I got you.
Yes, of course determining support and resistance can be determined in many ways. It is also dependent on your point of reference. If you are scalping on say a 5 min chart -- then support and resistance points will be different if you are trading a swing trade. I always use 3 charts. For scalping, I use a 30min, 15 and 30-minute charts. Now some like for example Tom Sosnoff will just draw a horizontal line across Highs and another line across lows -- forming a channel. Others use Pivot Points. Some use Fibonacci ratios, It goes on and on. Whatever works consistently for you is the method you should adopt. The proof is that if you can easily find those support and resistance points and you see that the method you chose to find them is consistently right then you found the best way for you.
"Easy" means that (1) the points you pick respond to the market you are trading. (2) In other words, the price moves "obey" or respects those points. Some markets are easier than others to determine reliable support and resistance for me I find CL -- support and resistance do respect the levels I can quickly find on any time frame.
