Error Message: Notice No Symbols Matched Apply to filtering criteria

This message appeared for the first time last evening on explorations I have run for years. I does no wok at all on one watch list and sometimes works against other watch lists. I saw the stream on this with backtesting. I am however doing explorations.

I am using version 6 with TC2000 plug in.

I thought it was maybe a data problem but cannot find one. I also thought I put this up on the forum last evening but received notification that it needs approval. Don’t know what gives but lets see what happens.

Thanks for any help
