Mark,
Thanks for responding.
I already do that. My specific problem is that I want to catch the value at 10 secs before the off. As you will be aware, race starts can be delayed for many reasons, and if I have backed the 3rd fav (say), it may not have been the 3rd fav when the race started, so when I look at my results, I might see that I have backed the 2nd fav at start time. Hence my stats can never be accurate.
I simply want to "freeze" prices and sel_order at 10 secs, back the selection based on those values, and my stats will be as exact as they can be when I transfer the data to my stats sheet.
I hope I have explained that correctly, and thanks again for your input.
