Mostly correct. I use other areas of support I see beyond just the current DMAs. the SPY/SPLG doesnt tend to breach the DMA and then bounce back up. it tends to get bought just above it by a dozen or so basis points. There are also spots where it caught support in between the DMAs for various reasons. The red circles are generally the spots I would have been looking to buy/add since the index rose above the 50-DMA back in late March.Gonna speak for Sanrith and potentially get corrected. He uses DMA's to determine entry and exits. For example let's use this chart:

We can see the QQQ is above all levels of support (20, 50, 100, 200). I've personally drawn a blue line to mark historical growth (pre-2016) and red lines to show growth post-2016. I could probably even do post covid lines as well.
Basically, you don't want to invest in the QQQ atm bc it's in growth mode (above support). You'll want to invest when it falls and hits lower levels of support like the 100 or 200 day, bc you know that it's consolidating lower to come back up.
So, if I followed my own GD rules, I would've maxxed out my QQQ investment in 2019, again in 2020, and in Oct/Nov 22, bc it was contracting below the blue pre-2016 growth and the normal growth.
edit: so based on this reasoning, it we breach the 50-DMA, the red circles are areas I would be thinking about adding (in addition to the 100/200 DMA and the long term support level).
