      I have found that the one-minute bar chart is the best way to read theTicks. The Ticks will trend, for the most part. However, when programtrading or a strong shift in market sentiment takes place, the Ticks willspike 200-300 points or more in less than a minute. This is the bestpredictive tick indication that program trading has been initiated.Additionally, it is a high probability indication of a reversal if theTicks retrace more than 200 points in less than a minute, and an extremelyhigh probability indication of a reversal if the Ticks retrace more than300 points in the same amount of time. However, if the Ticks reversesharply in the two minutes following the spike, disregard the indicator,and be very careful if you have entered a position based primarily on theTick spike.
