Some brokers will now, (2009), grant access to auction periods for us normal punters, you will need to have level 2 access DMA (Direct market access). I know IG Markets offer the service with CFD's to UK markets, Interactive Brokers offer it, I think, but not for UK equities. All brokers ask that you understand what you are doing before they let you loose with DMA, you can upset the big boys if you are messing around with it, so read up well before using. It is a useful tool in the armoury! Strange things can happen … I have sold at a greater price than I was asking!
