distance StopLoss et TakeProfit

hello
 in my  system I would increase  the SL and TP. ( public double distanceMultiplier { get; set; })
 each trade perdand I would increase the distance of TakeProfit and StopLoss and return when the trade is a winner...Comme a martingale.
 somebody t it a solution?
 cordially.
