Hi,
This looks like something a naughty child has drawn on your chart. I have never seen a Gann Grid, is there any way you care to add some narrative to let a dumb reader know what this represents?
The first one I think is a blast radius. Everything in white is dead. Outward from there survival colors go from roaches, to Megadeth fans, to radiation-ghouls, and finally the general population.
Seems like there’s a candle of interest in the core of the pretty picture…
From my chart reading only, it signals a major uptrend change of direction (as in reversal, not retracement).
ROFL - that made my day
