If you use technical analysis, there is a new free on line application called TimeToTrade (http://www.timetotrade.co.uk), which will notify you when price, volume and technical analysis chart conditions are met.
For example, you can create an alert that will notify you every time the Stochastic indicator for a UK/US stock (or option) falls below 20%, followed by the price rising above its 20 day moving average.
