Start of series 32 ppl short, 32 long. Hold till one group gains 8-10%, assuming it moves that much. Everyone squares off once either of the group reaches margin call.
Now 32 people who are winners in month 1 wait for month 2. Divide these in 2 groups of 16 each and repeat.
And so on...
At the end of 6 months there will be 1 person who has been a winner in all 6 series
still won't work
This assumes month after month for 6 months a single account is going to get into winning streak. Sure streaks occur but to capture such a streak you need thousands of user accounts can't do with 64 accounts, if you are randomly throwing darts.
This example works for coin toss experiments where one half the group is guaranteed to win for every toss, in our case there is NO such guarantee, lets say in the second month what if all 32 accounts enter into a draw down and each recover their draw downs for next 3-5 months? Remember most traders who lost their money in first year of trading are still trying to recover it after 5 to 10+ years! Okay what if this dreadful draw down happens in 3rd, 4th, or 5th month?
What do you think the chances of reaping 8-10% winning streak for 6 months with any of 64 accounts provided 90% of those account are statistically doomed as you are playing without edge?
Atleast in coin toss win probability is 50% and expectancy can be decent if you win to loss ratio is big enough.
Imagine you are throwing 64 darts from 100 meters into a circle of 1 meter diameter?
You think easily 32 darts will get into this 1 meter circle.... and you think, one lucky dart is going to get into circle for 6 times...
Chances are so good all your 64 darts won't make 8-10% in first month itself
(Remember out of 35000 zerodha customers only few hundred people managed to break even or something similar I don't remember the exact stat!).
