Sure its not a gravestone doji candle, on record high volume, indicating exhaustion, reversal signal? The bulls had control all day, but couldn't sustain it, bears took over, SP ending up precisely back at the open. Bulls gave all gains away. It's not important why this happened (T+3, Profit taking, Day Traders bailing, whatever), just that this is what happened. Others here have said the same, suggesting it's a Shooting Star, but the differences are v. subtle, nuanced, almost indistinguishable. (No upward opening gap indicates its a gravestone doji candle, to me, but not really important).
In either case, ALWAYS subject to confirmation. Tuesday will confirm...or deny.
DYOR - Just my 2 cents
