Thanks Angela... Not sure why, but I had to let Excel repair that file...??? Should be fun to see what these do for performance. Mark | ||

Same with me. I got the following message: "Excel completed file level validation and repair. Some parts of this workbook may have been repaired or discarded." | ||

Hi Angela Question re trending strats - is the same Strat logic used for each of the separate groups? Have the Strat params been "tuned" separately for the separate groups? How many symbols are used for each group? The whole MG list, or culled by liquidity, etc? Thanks - this looks like a good addition to the mix. [Edited by Jim Dean on 3/8/2013 1:12 PM] | ||

I've reposted the file as an XLS. It's working now. The same strategy was applied to each list. Each list is a subset of the group. I'll compile the lists for each strategy to post to the site when I have a chance. It won't be today. | ||

Jim - was just curious concerning your thoughts on how to use the new Trending strategies. I created a portfolio last night of 7 strategies which were profitable and had increasing yield curves for the last 2 months. I get the feeling because of the stock list breakdown that a sector rotation approach on relatively recent (< 3months) data is better than looking at data from more than 1-2 years ago. Since it is the same strategy used on just different sector lists, that seems to make sense to me. Some of the recent yield curves since Jan 1 look good and others look terrible. It could just be an issue of how well or poorly a sector has been performing since Jan 1. Any thoughts? | ||

Hi Bob- It's sort of difficult to say much specifically re the strats since we know very few details. For Trending strats of any sort, FILTERS are the key IMHO. Quite a while back I offered to share a nine-market-state indicator for Nirvana to incorporate for such purposes - never heard anything back about it though. I've requested that OVest allow us to define filters for each of the canned strats, but I sort of doubt that will happen. Also, as for all types of strats, I believe that the sophistication of exit logic has a greater impact on Strat performance than the entry logic. That's why I've asked for lots of different exit options to be made avail. Again, I sort of doubt that will happen. As I see it, OmniVest strategies are intended more or less to be "take it or leave it" - and that the users are to put portfolios together based on empirical fiddling around with equity curves rather than careful thought based in understanding the details of the strategies themselves. And, although that's not my normal way of thinking, I am nonetheless drawn to the concept - rather than being like a chess game, it's sort of like one of those 2000-piece jigsaw puzzles. In my opinion, the thing that will make OmniVest "work" along those lines is unrelated to the specifics of the strategies - it all hangs on the sophistication and versatility of the risk control and money management options provided. Still a long way to go in in that department, but I'm looking forward to when they have time to really concentrate more on it. Hopefully, part of that MMgmt suite will include the ability for the user to draw on the nime Market State model, and direct which strategies can be applied as a function of market state. I hope this long rambling story helps somehow. | ||

Thanks Jim for your insight. I do precisely remember your 9-market-state filter you offered to Nirvana and thought that was a key success factor and specifically for longer-term strategies like these new Trending. I wonder if DSS has been employed on these which may be sort of like your 9-market-state filter but of course not the same. Well, we'll all know more information soon. I'm just happy to see some new strategies other than RTM. Thanks again! | ||

Does anyone else have concerns that 'emperically tweaking" a portfolio with multiple strategies for optimal ending equity is prone to "curve fitting"? As of now there is no way to "forward test" this portfolio and compare Backtest results to Forward test results. I've said this in the past that OV really needs both a start date AND an end date capability in the simulation mode. I believe this would allow some capability to forward test the portfolio. Thoughts? Gerry [Edited by Ger on 3/12/2013 5:11 PM] | ||

I absolutely agree that an ENDING date is necessary to make sense on the simulation. For instance considering 1/1/2007 to 3/1/2009, during a major down trend would say volumes regarding profitable versus non-profitable strategies. This would help tremendously to select strategies during different phases of the market. I have been trying to do this for multiple strategies looking at the monthly returns, but it's very time consuming. | ||
