Trade in the same scrip profits confusion

respected traders if i trade any scrip… suppose buy sell
50 55
52 54
56 60

will my profits be calculated on a per trade basis=11
or avg price of buying and selling=3.66

It would be on the difference between average sell and buy i.e 56.33 - 52.66 (respectively) = 3.66.

3.66 x 3 = 11. Need to add quantities so final profit will be same in any case.
