Market postponed rules

Hey guys,

I know this is somewhere written already, but couldn't find where :)

So if the match is postponed (like Derby - Nottingham forest today) then as I understood... all the bets are voided. So if I have hedged pre-match for a few ticks  loss in that market, then that means that the money (the loss amount) will be returned to my account ??  And the same goes for profit, yes ??

Thanx in advance
