What you are seeing on the chart shown below is called a bearish reversal wick. I call them termination wicks. Whatever the name, a very long candle wick is informative for chart readers because it captures the mood of the period and helps with decision making for trading the periods that follow. This wick today was exceptional. Silvers moves higher had been very aggressive all month, but once refused its price rejection was profound and severe. The strength of the reversal is suggesting that this decline in prices will not end as quickly as bulls might hope.
