Are you referring the a 50/200 golden cross on the daily? Wasn’t sure as I run the 50 & 200 emas vs. smas on my daily chart. That other chart I posted above was a 60-minute, in which you can see a 130-period ema up on the top with the indicators although you can’t make out the line on the chart since I had the brightness muted down quite a bit.
The 120-ema does a pretty decent job of defining trends on the 60-minute chart, as you can see it has recently. Also note that QQQ is now testing it from below (resistance). It is also worth noting that the Q’s are also testing the key 200-day ema from below as well, another simple & fairly effective stand-alone ema that does a pretty decent job of defining trends on the daily frame, especially with the QQQ & many of it’s top components.
