$SOS it’s by no means a magic eight ball, and no technical indicator is definitive, nor is any system of indicators. Someone was in love with Parabolic SAR here earlier, and didn’t understand the reference when I called it a stochastic- apparently the underlying math that gets used and the formula used to derive both escaped someone. This is the MACD. It’s a series of moving average crossovers and divergences. The circled portion is basically saying a shorter-term average is crossing above a longer term one, and that they’re both starting to curl up on the daily chart. This is a trailing indicator, which means it only tells you in another visual way pretty much the exact same information on the chart, but it can be a helpful visualization. If you’ve never used it before, it might be worth taking a look.
