Quote from abattia:
Is it possible? Yes.
Is it likely?
You can estimate how likely as follows (which assumes the probability of a single winning trade is binomially distributed, and also that the probability of any trade winning is independent of the wins and losses that have gone before ... all of which could, and will, be disputed)...
For case of a single trade with a 50% probability of being a winner ...
P(10,000 wins in a row) = (0.5)^10,000 = .... ?
.... this number is nearly zero ... something like 3 x 10^-3,030
If you assume the universe is 15 billion years old (again, this is something that can be disputed), that's not quite 5 x 10^17 seconds.
So, even if 10,000 round trip trades were completed every second since the universe began, there is still an almost vanishingly small probability of having seen 10,000 winners in a row during any 1 of those trials.
Now, if you did 10^200 of these 10,000 round trip trials every second (that's a lot of volume) since the beginning of the universe, there is a better chance you might have seen at least one 10,000 long winning streak.
So it's possible, but not likely.
