Tools—Chaser
The Chaser Tool chases a price until it gets matched. You can set it to move any number of ticks, at any time interval for any number of ticks. In this example we have set it for the horse Polyfast to move 1 tick, every 10 seconds for a maximum 15 ticks. You can do this on the back or lay side for any selection or all of them.
