Hi All,

Westpac advised that they do not cater for "Trailing Stop Losses". Any idea what brokers do?

Here's the gist of what i'm after(obtained from INVESTORWORDS.COM): "A complex stop-loss order in which the stop loss price is set at some fixed percentage below the market price. If the market price rises, the stop loss price rises proportionately, but if the stock price falls, the stop loss price doesn't change. This technique allows an investor to set a limit on the maximum possible loss without setting a limit on the maximum possible gain, and without requiring paying attention to the investment on an ongoing basis."

..sounds just bonza to me.
