Chrome,

I am certain you can put the bet on in the live market (fixed odds) and leave it at $1000. You then mark it to go to SP if not matched and to go to Market.

You just cancel your $5 in the mean time before the market goes to SP. That leaves you with $1 that will go to "market" in the SP when the market is suspended.

Im 95% certain it will work but I need to give it a go. I'll try tonight but I need to write a separate program to do it so it may need to wait a couple of days.
