Stock Scanner and Trading Platform for FTSE

Hi,

I'm new to the site and Day Trading, so wondering if someone with the expertise could help me.

I'm looking for the best Stock Scanner and Trading Platform to be used from Australia on the FTSE for Intra Day Trading? (or one platform for both)

For the Stock Scanner I'm looking for one that can show top gainers and losers for a specific size volume, nothing too complex.

Any thoughts or comments would be very welcome
