Stoploss Trigger Spreadsheet

[greenbrokerjohn]

Being new to Stop/Loss, I've been having a look at the Stoploss Trigger spreadsheet available on the forum. I understand the main principles, but I have a few questions.

1. Do I make the back bet with BA before in-running?
2. There are two cells named stoploss with number 2 below. Why two, and do I have to fill both in?
3. Do I put my stake in cell U5, or is that put in automatically?
4. Can I back more than one horse in a race (as I will not be able to put the horses position in the market in cell T2)?
5. Could somebody give me a step-by-step example of how to set a stoploss up using the spreadsheet?

Overall, a VG spreadsheet.

Thanks.
