I have used Metastock, end of day, for over 3 years now and find it has provided me with all the tools necessary for profitable trading. The tool you are referring to in Metastock for scanning, is the Explorer, and you can scan all the LSE, or against any list you wish to set up, in less than one minute against one of the criteria built into the system or your own formulae, which you can develop with the aid of the tools built in. There is a learning curve, but if you are familiar with Omni then you should have no difficulty, as there is a 538 page manual to assist, together with email support direct from Equis, which I have found very prompt with a response.
There is a version for intra day trading, but would advise getting used to the EOD version first.
I obtained mine from Q-data, who are data providers and give an excellent service both on advice on Metastock and upgrading any data. You can contact them bye email to: ruth@qdata.co.uk or tel: 01594 810077/fax 810851
Best wishes and may you trade profitably
