Trailing Stop-Loss, lay then back
It remembers the selections you laid on, then monitors their back price. If it keeps growing, the current back odds are constantly remembered. As soon as the price has dropped by 5 or more ticks from the last highest value, the trigger places a back bet to save your profits or minimize your risks.
Here is a picture to illustrate the example. There was a lay bet placed on "Dancing Poppy", then its price started dropping until it reached 5.6, and the trigger kicked in and placed a back bet to minimize potential loss on that selection. The second selection, Abriachan, is still waiting because its price hasn't decreased enough for the trigger to distribute the loss.
You can edit the number of ticks by which the price may change in the trigger called "setting stop-loss in price ticks".
