A: There are many settings that can be different between focus lists & one variance is all that is required to get completely contrasting results. Here are some basic settings to check in each profile: 1. Strategies applied. Do you have the same strategies applied to both profiles? 2. Timeframes enabled. Check Edit/Data Periods, the amount of data can have an affect. 3. Backtest Period. The same amount of bars need to be set in the ToDo list/Test Settings. Also the hash mark line in the chart forming a rectangle around your backtest period needs to have the same begin & end dates. See #4. 4. Optimization Boundaries. http://www.omnitrader.com/currentclients/OTforum/thread-view.asp?threadid=1086&posts=1 *Note that these first 4 are contained in the profile, so copying the profile from one instance to the other would make these identical. Try creating a new focus list by clicking File/New & don't change any of the default settings & just add the one stock to the list. Then do the same thing with another new focus list. This should produce the same results. Furthermore, if you're trying to get the same results between 2 different computers or 2 different versions of OmniTrader, there are other things to consider as well: 4. Version of program should be identical. Check Help/About. OT2017 may not have matching results with OT2016 and pre-release 5D may not match with Release 2. 5. Data. You would want to be using the same data feed and have the same updated data on both. For example, eSignal may have slight differences in data than TC2000. Also one pc may have more updated TC2000 data then another pc with TC2000. Differences in data can easily change analysis results. 5a. Click Edit -> Data Settings -> Advanced -> Stocks. It is recommended that only the second Automatic Split Adjustment setting is enabled & the rest disabled. 5b. Click Edit -> Exchange Information & make sure the default exchange is the same, the default is NASDAQ. (This wouldn't affect the voteline, but may affect Portfolio Simulation). 6. Holidays or exchange sessions could be different. Both are contained in the exchangeinfo.otd file located in the C:\Program Files\Nirvana\data folder. You could try copying this file from one machine to another or check the holidays (Edit/Holiday Information) & exchange sessions (Edit/Exchange Information) manually.
