I used to like them but now find they are a distraction.
What seems to help grok the whole picture is a line showing, yesterdays close another for yesterday's high and yesterday's low. Just the Pivot, not R1,S1, M1, M-1 or the rest. They provide hindsight, IMO.
Then I have the average of the first 5-minutes of the day. That and the price action of the first 60-minutes show me the trend for the day 75% of the time.
Finally, the support-resistance lines are a moving target during the day. ES had a support at 1034 while the world waited for the FOMC decision. The market opened up, didn't fade the gap, the trend is up, so buying at 1034.25 was a bit of a gamble but with a breakout of the resistance at 1035.25, nothing else counted.
Oh, I also put in a line once I figure which way the market will go for the rest of the day at the anticipated high or low based on the average range of the last 5-days. Today it exceeded the projected level.
Best wishes,
