This is not what you want to see for $ZEC . First big candle was on modest volume, the second candle was small bodied on decreasing (compression) volume, and the current candle is looking like it wants to reverse or stall.
This is not what you want to see if this was a legitimate push up. You need to see volume expansion. I always look for this to confirm a legitimate rally. A single, explosive candle, in a macro downtrend, is always the first warning.
Understand that the market makers are allowing price to rise on retail money as that costs them nothing. They let the trend exhaust and then they short it.
