Hi Doug I and others had a problem a while back but the one of the latest updates cured it. I think it was an RSI filter issue from memory. Certainly no probs with 4C. Best Richard | ||

Within the last few days Richard.ots will not function with 2005-4H. With Richared.ots installed the other .ots's will not function and upon closing an error message is generated. Any ideas? J | ||

thats the one. I wish I could help you further but there have been a number of releases of OT2005/6 since my strategy was released so Support is your best bet. Regards Richard | ||

Hi Richard: I studied with interest your strategy, Richard.ots some time back. I am looking at it now with some more knowledge of OT and of market. Have you further worked on it? Thank you. -Chandra Sekhar | ||

Hi Richard. In your popular posting of the strategy Richard.ots (postin 6494) can you tell me how did you "reduced the symbols with BT 100% FT 100%"? Thanks. -Chandra | ||

CSekhar, In the focus list is a symbol somthing like a funnel click on it and a box will appear set the settings in Criteria. Chapter 3 of the Omnitrader user guide has a lot of info you might find important(To set the filter the way you prefer) ![]() | ||

Thanks for your response. Here is my problem: Richard ran his strategy on sp500 with BT=250/FT=250. Out of the resulted list, he selected those symbols with BTHR=100% & FTHR=100%. This filtered and has reduced his list. Now, on this filtered list, he ran his strategy with BT=250/FT=0. Now he must have ended up with a smalle list. This is what I want to do. So, (i) I ran the strategy on sp500. (ii) I went to funel and set BTHR = 100. It filtered my list to ONLY those with BTHR=100. (iii) Next, I went to funnel and set FTHR = 100. This further reduced the list to those symbols that have BTHR=100 AND FTHR=100. (iv) Now,I tried to run my strategy ONLY on this list with BT=250 and FTHR=0. But the strategy runs on all 500 symbols of SP500 (unfiltered, original list of SP500).. I do not want it to run on all 500 symbols of SP500. I just want the strategy to run on those symbols which secured BTHR=100 and FTHR=100. How can I do this? -Chandra. | ||

Hi - just saw the thread. The answer is very easy. Once you have run the BT 250 FT 250, leave the funnel unset (no filter) in the focus list. Order by BT% descending and then FT% descending. Select all symbols in your list which do not match 100% on both BT and FT and choose the "remove symbols" from the focus list menu. This then leaves just a list of symbols passing the 100% test. Now run with BT 250, FT 0 on that reduced set. All the best Richard [Edited by RichardL on 2/19/2006 10:13 AM] | ||

No, the answer is not that simple. Once I finish analysis with BT=250/FT=250, I double-click on the title BTHR. Sure I get the list in decending order from BTHR=100% and down. The problem comes now. At this stage where all the symbols with BTHR=100% at the top of the list, if I double-click on the column head of FTHR, sure it sorts the list in its own decending order from 100%, but it does not retain the earlier decending order of the BTHR. So, I cannot get a list of symbols with both BTHR=100% and FTHR=100%. Thanks again. -Chandra | ||

Hi Richard: Here is another point of view that I think you should give thought to. After your first run (BT=250/FT=250), why don't you just sort the list for adviser rating (ADV)and just pick only those with high advisor rating for second run with BT=250/FT=0? Don't you think the ADV rating takes into account BTHR and FTHR?Just a thought though. -Chandra | ||

No - it is easy, just delete any stocks which havent BT 100% then delete anything remaining which doesn't have FT 100% Best regards Richard | ||

Ah! that would work! After sorting for BT100, delete all that comes below BT=100. Then sort the remaining on FT100 and delete all that come below FT=100!! It should work! Thanks. -Chandra Now, how about my second posting (re: ADv. Rating)? | ||

The ADV rating is a measure of systems in agreement ON THE CURRENT VOTED SIGNAL within a single strategy as I understand it. So the measure you see is that of the winning strategy on the current voted signal. But when you run multiple strategies (to cover a wide variety of possible stocks well), the All Strategies Voting (ASV) measure is used to rate strategies over all past & current votes within the test boundary. The best one "wins" and its signals are allowed through to the vote line. The BT and FT hit rates are meaningful in measuring the degree of "fit" to the personalities of the shares and the measure is that of the degree of success of OT harnessing the groups of strategies (ie a higher meta-measure than ADV). Others will be able to say this better than I do here, but this is my reasoning best regards Richard [Edited by RichardL on 2/19/2006 3:17 PM] | ||

That is good explination,Richard, on why I cannot use Adv.Rating when I use multiple strategies! Thank you. At last, I am able to run your BT=250/FT=250 and cull BTHR=100/FTHR=100 symbols!! But, now, (i) what is the benefit of running another analysis on this culled list with BT=250/FT=0 instead of using it as it is? One more question: (ii) Can we run BT=0/FT=250 instead of the BT=250/FT=0? Does it make any difference? In both cases, we are refering to the same data whether we call it BT or FT! Just curious to konw the difference. Thanks. -Chandra | ||

as I understand it: (i) more up to date data, instead of the Back Test being between 1-2 years old, it is 0-1 year old with BT 250, FT 0 (rather than BT 250, FT 250) since the FT test does not push it back 250bars=1year further into the past. Recent data is considered better in the event that the "personality of the stock" is changeable in >1 year periods (for 250 bars settings) (ii) the BT usually invokes optimisation, either overtly or otherwise (eg the ASV test which cherry picks strategies based on their results) in the strategies to fix optimal settings (and choices of strategy) based on data in the BT period, whereas the FT uses those fixed settings in the same strategies when they process FT data. ie its not usually the same. You can tell this by looking at the % hit rate using performance reports on BT 250 and FT 250 over different date settings for "non-optimising" ie mechanical strategies You would anticipate BTHR% and FTHR% to be roughly equal always for so-called non optimising or mechanical systems but they seldom are in practice indicating that there is some difference occurring in test/use which introduces asymmetry in the results. Again my understanding which is empirical. best Richard | ||

hello RichardL . I'm a newer user to omnitrader,trying to help my family income, and have been very interested in your strategy. I ran a report on my symbols list using your stategy and it showed a @70% HIT RATE. My frustration with omnitrader has been the optimization,you never can get an accurate backtest and signals change on me. my question to you is will your signals on this strategy change also. I would hope this message doesn't disturb you . You sound very famaliar with omnitrader and would appreciate your thoughts.thank you, tony | ||

Thanks Tony To be honest, you have to separate out the two key functions of OT, one being prospection and the other managing a placed trade. On prospection, unless you run a mechanical system with no optimisation (be careful in the way that OT deals with multiple strategies using All Signals Voting also), you will use optimisation carefully knowing that the systems are trying to tune to the most recent data. As events change, bars update, inevitably those systems will reflect the changed circumstances in different (possibly) signals between observations. You have to take a balanced view at the time the bar is complete whether to place a trade on the results of that prospection run. The system isn't telling you its a great trade (ie certainty right up to exit), its saying its a great entry signal (ie possibility) Once you've decided to place the trade, OT can then be used, via the trade plan, to manage the trade & reduce risk, emotion etc in the way you've set it up. Thats also why the portfolio helpfully offers to switch off optimisation for trades in trade. Sorry to labour the point, but these two functions I mention at the beginning are quite separate in OT functionality and use (for me at least) My own strategy was based on reviewing Jeff Drake's excellent booklets on reviewing charts. I designed a chart template (posted in this thread) to address these and the strategy to pick up only those stocks which fitted the charts I wanted to see (so I didn't have to scroll through the whole list). Glad the hit rate remains high but to be honest you have to read Jeff's books & understand what to look for in the charts to see its full benefit. Not every signal is going to be a good one. all the best Richard |
