AM,
I would also be interested in some tests in other markets esp. the bonds, but also don`t have data to do. Would be of only academic use the next time, cause i have not the accountsize to trade a portfolio of markets, that`s the reason i`m reduced on just the YM. If you go through the literature you find Openrange Breakout a very old principle used in Commodities in the first place, so i have no doubt to work in those markets you mentioned.
The ES is simply the most noisiest market to choose with a lot of chop and retracements, this in every timeframe. I did some tests about the "trendiness" of common indices like Dow, German DAX, and S&P over some years of sample and the worst is the S&P. If you ever tried to develop a daily trendfollower on indices you get the same results, S&P does not work, on the other hand, i don`t like countertrend systems, but the best results you get in the S&P with so called Overbought/sold systems. The less noise, the more "trendy" a market behave, the better i also expect an Openrangebreakoutsystem to work.
The NQ behave`s more trendy on daily base, daily trendfollowing works, but on intraday timeframes may be also to much chop and noise, i did not look to deep into the reasons why exactly...I`m quite satisfied with the knowledge that the YM and ER are the better choice, but in the case of changing marketbehavior i like to see at least a weak positive performance in the other indices too.
So, a good idea is some kind of analysis about the noiselevel or trendiness of a chosen market over a larger sample to define if this market is a good or bad choice for the princible of the used system.
You can use an afternoon breakout instead or you trade a break of the Openrange only in the afternoon, i just found the most netprofit ( of my YM system )was made in the timeframe between 01.30 and 02.40 for entries, the other times plays a more marginal rule, the reason may be the higher activity of "professionell money" in the afternoon, you find trends more consistent after Lunch, but that me be not the same in other markets like FX, Bonds etc.
I think some "intelligent" kind of breakoutsystem will behave most robust over most markets over time, i`m completely off those countertrend stuff, that`s something for quick scalpers or the guys with the very deep pockets.
Uuh, if anybody has data from ZN,ZB for me I would enjoy to public some tests...
