Martingale (betting system) formula

Hello threre I need a Martingale (betting system) formula to convert signals. I receive signals in container > 1 for hit -1 for loose e.g > 1,-1, -1, -1, 1 I have following variables x = stake(ammount) y = factor or martigne e.g. 2 for 2xstake on loose z = factor of income * stake so if we have like: x = 1 y = 2 z = 1 1,-1,-1,-1,1 i would need to get 1,0, -2, -4, 2 = 2 or x = 2 y = 3 z = 2 1,-1,-1,1,1,1-1 = 4, -2, -4, 0, 4, 8, 12, 10 = 10 I hope I have made it correct. Please let me know if you have any question
