Personalized monthly returns is wrong

Matthew,



I’ve played a little bit with personalized monthly returns in my system (Tango) and results that I have is very strange. I would appreciate if you clarify a little bit how performance in my example was calculated by C2.



I took nearest unprofitable month in my system - 03/2009



Default Hypothetical Monthly Results

03/2009 result is (2.7%)



Adjusted Monthly Returns (based on personalization)



Start trading a system with amount 50,000

Show commission costs? yes



Stocks only

Up to this quantity 1000 - 0.005 per share



03/2009 personalized result is (9.5)



Amount of stocks that was traded in the months ~22K for 200K trading capital. I would assume that 4 times less for 50K (smile) in personalized monthly returns.



So commissions for 03/2009 month is ~$220



Well… difference between hypothetical and personalized result is 6.8% or ~$13K (!) in commissions for 200K capital accordingly my personalization.



I would say there is huge difference between $220 bucks and $13000 paid in commissions.



At the moment my assumption is that personalized results aren’t trustable stats in new C2.



Thank you,

Eu
