Stopping Volume Pattern (Emini 5 minute)

Professional profit taking is occurring when the following conditions are met:

    * Volume is greater than the previous bar’s volume
    * Range is less than the previous bar’s range
    * A new high is made (in an uptrend) or a new low (in a downtrend), and
    * Closes off the highs (in an uptrend) or off the lows (in a downtrend)

The reduction in the bar’s range is the real key. 
It shows that additional selling (in an uptrend) or additional buying (in a downtrend) 
is keeping the bar’s range low. So Professional traders are taking profits and/or 
"fading" the current trend.

You will almost always see Stopping Volume patterns leading up to a market turning point. 
However, if the trend is strong it might take several Stopping Volume patterns in a row 
to slow the trend. Remember, most turning points are Stopping Volume patterns, 
but not all Stopping Volume patterns are turning points!
