This indicator shows the 99MA daily (dotted) and 4H (solid) moving averages on all timeframes. It defaults to the 99MA, but you can change it to 25MA or whatever your heart desires. Why would you want to use this? Cause the 99MA is like magic for altcoins, presumably because it's the largest default MA on Binance and lots of people are watching it.
If you can see where the daily and 4h MA lines are, even while looking at a 1h or 30m chart, then you'll know more about the areas where price might do predictable stuff.
