/*
22 September 2005 by Varus
variables added:
gAlert External switch to allow alerts.
gBuyAlertGiven Global to stop the alerts being displayed more than once.
gSellAlertGiven Global to stop the alerts being displayed more than once.
An alert was added to alert the trader when the indicator changes from a long signal
to a short or the other way round.
The value of CountBars was changed to 400 from 300 to give a longer display of previous
performance on the price chart.
Version number v1.01 added to filename.
