SPY Possible reversal after closing at Low Of Week (LOW)

I saw an interesting chart a while back on TV from a user whose name i can't remember anymore. The user showed that when a week closes near or at the Low Of Week (LOW) it has a high probability of reversing the next week. Not a general rule, but i think it was ES/SPY specific.

I'm not taking nor holding any position with SPY. I also don't see it making a new ATH and i have a short bias for all indices at the moment. Just a thought i wanted to share.
