So, for SURE it is possible to beat "the market", but:

- strategy is limited up to max 1mio per account (well, maybe 2 pr 3)

- you need a tailored software, tools like MT/et al wont help you

- with a leverage of 5-10, its possible to achieve gigantic returns

- system needs to be capable of going short as well

- your individual application should abstract-away all dauly charting&news noise: what counts is statistics and propability only, do not check CNN et al

EDIT: - this approach cant be done by ANY institutional corp due to regulations, so they are not doing it
