[amibroker] Help With Indicator

["Ken Henderson" <kjh@xxxxxxxxxxxxxxx>]

 Hi

 

Can anyone suggest a solution to a problem with the indicator code below.  

 

I can am able to gain an up arrow on the chart for a buy signal but am
unable to obtain a down arrow for a sell condition no matter what I do.
What am I missing here.

 

Many thanks in advance.

 

Ken
