Quote from NeoRio1:
Your discretionary trades are killing you. Why don't you abolish the "limited" discretionary trades for a couple weeks?
You think you are making a change but you keep on conducting the same failed experiment over and over and over. Just now instead of conducting the same failed experiment daily you conduct it weekly.
You use to be the best pitcher in the majors with the best curveball. This year the batters are hitting your curveball out of the park left and right and yet you still keep throwing that same curveball.
To put it frankly you are stubborn as hell, you fell in love with a method and show no willingness to give it up.
Pull the plug, the bitch is dead!
How can I get killed when expectancy is on my side? So let me pull the trigger once more... An unfounded application of otherwise rigorous mathematics is in practice as simple as proving that all cats are black using induction. Logic is indeed always impeccable, math sufficiently rigorous, and the only catch is the initial assumption. The first cat need not be black, returns continuous, defaults uncorrelated. Edge need not be stable over all time periods as the Kelly's static model implicitly assumed (kudos to OP for trying to repair this fatal flaw using moving edge estimates - which in themselves required an assumption of the decay factor - not high enough apparently). Generously granting that edge was positive in the first place rather than merely being an unhedged exposure to some risk factors (long vega is a strong suspect here). It is much better to merely guess about what follows from more-relevant assumptions than derive precise conclusions from less-relevant assumptions. Especially when relying on economic quantities which are so hard to estimate as the 'edge' or alpha ('our estimates of expected return are so poor they are almost laughable' - F. Black)Quote from Port1385:
Its time to get out now. Your down 18 grand and next week might be another 18 grand. Next thing you know you will be like Lenny Dykstra getting sued by the brokerages because you blew the account and couldnt repay the margin loan.

neke,
don't listen to most of those who are acting as advisors to you, because they have no clue what they are talking about.
If you listen to my advice, you will avoid being misled by them.
