NASDAQ 100 orphans

In one of my models, I'm ending my backtest with open positions in STRZA, VMED, and LLTC. None of these will graph, and none of them show up as valid symbols in Yahoo or at Nasdaq.com. A problem with this Universe? Are these orphans and their positions never got closed in the Rotation model's algorithm?

Hey bitfool, I think I know what's going on here. The backtester has special logic to close out the orphans at the close on the date they leave the index, but it looks like the weekly scale is throwing off this logic. I will look into fixing this today and post back when completed.
