BULLISH Signal flash with 2008 failure example

There is some discussion taking place regarding the divergence of SPY and HYG during the last few days and this divergence is a signal for marking the market bottom.

I would like to point out while this generally is a true indication of a potential reversal/bottom (under normal circumstances).
We are not dealing with normal circumstances.

The same signal existed in 2008 (also not normal circumstances) between 2 Jun 08 - 19 Jun 08. The "rally" in SPY was very, very lite before failure. SPY only "rallied" 2.7% before
cycling back down another 10%, holding in range for 2 months then waterfalling down another 38%.

Use extreme caution IF trading this signal.
I would consider this signal as being "Set-up", the "Follow-Thru" would be price moving above 373.04

2008 required a follow-thru above 141.17, "rally" price high was 137.12 which obviously failed to reach the follow-thru requirement and prices failed through the support. Down ~48% within 5 months.

This is not a prediction/forecast, this is pointing out potential of failure while others are discussing potential of success.
