Some sources I saw claimed "Gee we turned around just before we went into a bear market", and I thought of what I saw with parallel trend lines in my $SPX MACD charts. The prior MACD trends for $SPX were megaphone shaped, I am not sure what the shape change implies.
Look at the below chart - the top larger support line is like a water level of the surface on which we floated until around Sep 2021 (blue line), after which we began a smaller down trend, at least so far smaller. This current market barf I expected to bring MACD to the downtrend support line around -150, but so far it halted just above that at the larger lower support line, which starts at the Mar 2020 low. IMO this chart could indicate a bear if the larger lower support is broken as it follows the inner downtrend.
