I have a little run too, I'm currently on 3 winning streak but it's too late for this, I'm not sure which is harder to achieve, a win streak or a losing streak?
The probability of a having 7x losing streak is much higher than probability of having a 7x winning streak.
According to rules stated in
this thread, for having a valid 7x winning streak, the odds for all events must be greater than 1.5 and for having a valid 7x losing streak the odds for all events must be lower than 4.
Assuming the odds for all 7 events you bet on are exactly 1.5 and the house edge is 1%, your chance to having a valid 7x winning streak would be
(0.99/1.5)7 = 5.46%Assuming the odds for all 7 events you bet on are exactly 4 and the house edge is 1%, your chance to having a valid 7x losing streak would be
(1 - 0.99/4)7 = 13.66%
