First of all, sorry for the mistake. The figures I've posted above are months to recover from CTAs' worst drawdown + months when worst DD has taken place. The flat period in some cases is much longer. There's one study I've found regarding this subject, "How do CTAs' Return Distribution Characteristics affect their likehood of Survival" by Mr. Fernando Diz (
http://www.mfainfo.org/images/pdf/diz-rez.pdf ). He analyzed 925 programs during 1975-1995 period. On page 7 you'll see variable "Months to recover from Worst Drawdown". The mean for this figure was 21 months, avg 38% of program's life!
Now I have a question. How is it possible: 62% of votes say that your longest flat period was below 3 months, when the average learning curve for newbie traders is 6 months and 90% of all traders lose? What are possible reasons for this?
1) Only profitable traders responded to the poll
2) Sample is to small (only 16 votes)
3) Traders who have responded to the poll trade for a short period of time
4) ET Members outperform CTAs...

in terms of return, risk, flat periods, etc. b/c they trade with much smaller capital, more frequently (day trading).
What do you think?
