Can anyone tell me of a way to calculate daily support and resistance levels without having to kill me? I am in the process of using free yahoo data using only the high/low of the day to calculate Market Profile TPO horizontal support and resistance levels. My intentions are to test if a given signal(s) works better if the setup includes these S/R levels. I have heard that S/R levels and trend lines are not easy to calculate( don't care about trend lines). I am getting somewhere following this method but am wondering if a paper/.pdf of "another" known generic method of calculating s/r levels is out there. Am using excel vba and .csv files........Thanks in advance. Have to say that I haven't posted in this strategy forum and rate as a beginner and can now hear the collective........."no shit"
