if so , if later you want to put the books in a bookshelf, do you again wrap the paper cover outside the hardcover ? i feel a compulsion to discard the paper cover forever, though do not know if it is an irregular behaviour.

When you buy hardcover books, there is usually a paper cover with book /author/publisher name outside the real hardcover core. I am just curious, when you read the book, do you uncover the paper cover outside the hardcover, or do you just read the book with the paper cover on. Just...

As for K200 option series, when can IB supply greeks/ IV in the optiontraders ?

Ron Do you trade every trading idea you have in mind with REAL money ? trading strategies need thourough test before go alive, so do the position sizing models. A book by Ryan Jones " Playing numbers to become millionaire"( I do not remember the exact name, as it is now 6:12 am here and I...

Hi, I have mentioned in my original post that this is a "general question", hint that without go to specifics, I hope to talk about the basis for comparing different position sizing methods. So it is not important whether it is fixed ratio or fixed fractional or fixed amount per contract or any...

I do not understand why you repeat what you have said in PM in the public forum. I have indicated I prefer to talk about this PRIVATELY.

i sent you a PM

thanks, looks time to abandon my excel MC test file :-)

but the program for Monte Carlo test looks nice, Robin, where did you find it ?

Sure, but it is intraday system. 6 month can yield hundreds of trades, 6 month result, IMO, is not long enough to be significant even for intraday systems. 6 month of 2001 and 6 month of 2007 are surely different. And Monte Carlo simulation, by definition, can yield countless combinations...

Hey Monte carlo test is not enough, bcz it cannot reveal the potential problem of your strategy if the imputted sample is not representative

Hi, I am testing different position sizing methods and come up with a general question in this category: how should we compare different position sizing methods? As we know, if you decrease the delta in a fixed ratio algorithem, or increase the risk percentage in a fixed fractional algorithem...

Yes, I am testing different position sizing algorithm. I read MJ's posts several years ago but seems cannot find the specific one you mentioned. He used to have a site, (or right?) but seems I cannot find it either.

robin, as i have said several times before, the system whose snapshot are posted here should have been thouroughly tested, before being traded in realtime. there is some sign of overoptimization there. you may deny , as there are several hundreds samples there, but that's not enough. I have...

Hi, I am considering a MM plan for a small test account. The motive is to adopt fixed ratio position sizing when the account is small , to take advantage of the higher speed of expansion that fixed ratio can bring, and then switch to fixed fractional when the account has built up some size and...

Maybe there is a reason why most traders focus on strategy part of the trading. Because position sizing algorithms such as fixed fractional or fixed ratio work best for strategies with low drawdowns or smooth equity curves. So to benefit most from position sizing, one need to first find a good...

Hi, I am also considering an efficient way to scale up trading. I am choosing between fixed fractional and fixed ratio method. The former is a bit slower for me , so I am considering fixed ratio method. The point is I am curios to know, what is the weak point of this position sizing...

Money management, together with trading strategy and trading psychology, are three mainstains of trading . After lurking in ET 3 years, I just realized that there is no forum dedicated to money management, or position sizing, is it possible to add one ?

Do not trade a system with real money ( or at least with big money) until you are comfortable with the fluctuation of its equity curve . A thouroughly tested strategy may boost your confidence .
