This has only occured since Vers.8
I download a day's worth of markets. Tick all the boxes to load into My Markets. Go to My Markets and arrange in time order. All the markets are shown in light typeface and I check that all the data is present, see screen shot TM start.
I then start TM and markets start to be monitored and everything appears normal, see screen shot TM running 1.
After a while when a market should have finished, it still shows in Green Type and when checked the market data has disappeard, see screen shot TM running 2_market disappeared.
This happens to more and more markets as the run progresses and at the end, there are a lot of markets still displayed in green type, with no data present, see screenshot TM end run.
