Metastock - how to capture closing price on buy signal?

["Bob Hellen" <A2099767@xxxxxxxxxxxxxxx>]

I'm a relatively new user of Metastock 6.52 and want to improve my trading
rules using the system tester. I want to compare subsequent price movements
with the closing price when my system last triggered a buy signal but can't
find a way of capturing the closing price at that date. (it isn't as simple
as looking for "value when" the last occurrence of that rule occurred
-there may have been several since I entered long). Does anyone know how I
can do this?  Ideas much appreciated.
