I think it is available.

But here is my contention; stocks that delist don't just evaporate over night. They usually trend continually down for an extended period of time. Granted, a super long term weekly/monthly system may not capture that trend, but most daily and weekly systems would and therefore even though its delisted it would still have provided the opportunity prior. ONE is a classic example. It was a great trending and highly profitable stock at the time. Yes it no longer exists and could be considered as a candidate for survivorship bias. However, it should not have been detrimental to a portfolio's performance at the time.

Lets use an assumption in todays terms. Evans and Tate would be an example of a stock that is slowly going to oblivion; no different from HIH, ONE or SGW. Its clearly in no position to trigger a buy for such a system outlined in that report.

I think perhaps the difference in thinking is that whilst I may trade a trend in ABC Company, I do not look at that being a candidate ever again. There will always be another to take its specific place. Whereas survivorship bias relates specifically ABC company being available again.
