when to fire a stop loss trigger in tennis [TCKT24072013TNS]

hi,

I wondered if anyone had ideas on a condition to add to
the stop loss tick method.
Often stop loss triggers fire too early in a tennis event not giving sufficient
time for the player bet on to bounce back. For example, suppose a bet was placed on a fav at say 1.50. The odds suggests that the player is a strong fav. It is often the case a strong fav loses the first set, hence the odds drift out and a stop loss tick limit is reached and the distribute loss trigger fires and an overall loss is shown whoever wins. Usually the strong fav will go on and win.
I thought perhaps a condition saying SL trigger to be fired only after first set is completed.
Anyone have any other ideas on a suitable timing to fire a stop loss trigger?
Also how could I write a the condition described above.
Many thanks as always
