I have reprogrammed most of the Tradestation screens that I had lost. The only major thing still missing are my supply and demand indicators, which I was looking at less and less. They may have been marginally useful, but not so useful that it is worth spending a lot of time re-making them. They were quite complicated.
So the only major loss from the computer debacle seems likely to be my Chrome bookmarks — and the cost of a new computer.
