That makes perfect sense, because i also do that! recently i started making that chart thing and as a result allocated a purchase and sale value to all trades, if i added i would indicate this as 2 positions, then one can see the percentage gain on the first, second and third, etc acquisitions of the position. its quite cool to see. i have some gains of 17 times on EOH, but on average its 10 times. and on APN its 9.6 times or something.
