The SPY put in 3 low volume bars on April 6,7, and 8. These are the yellow bars that I point out on the chart.
Buyers pushed price above the high of the April 8th low volume bar and Friday's bar was just a "normal" buy bar. I say normal because there was no indication it was a low volume day, a churn bar, or climax volume day.
There is now at least a 60% chance that prices will continue to trend higher and the next target is 4200 on the S&P. We could experience a pullback but we are still going higher no doubt in my mind.
I have also pointed out with the yellow arrows what has happened in the recent past when price passes above these low volume bars.
There are several more examples I could point out in previous years. I have also seen this happen over and over again on the S&P intraday charts not to mention other equities where I have seen this as well.
