Bill,

The TNA stop on the robot page is INDICATIVE only. It is the daily best guess of the equivalent IWM stop based on average correlation and volatility of the 2 instruments. It does not even take into account dividends or splits, it is YOUR responsibility to monitor such events. The only true signal is dependent on IWM only.
There is no archive and there will never be. I would have preferred to avoid such indicative stops and limits on related ETFs because I KNOW we will have a big problem with them one day when we don't anticipate dividends or splits. I asked for help about this and nobody volunteered. After massive members requests, Pascal decided to leave the related ETFs price online, but use them at your own risks and perils and do your homework!
