[amibroker] Help with Dave Landry's Metastock 2/20 EMA Breakout System

["Joseph Landry" <jelandry@xxxxxxxxxxxxx>]

I'm looking for some help in decoding the attached statement 
especially this piece

Alert(Cross(Sum(L > Mov(C,20,E),2) = 2,.5),10)

I'm assuming that the Cross and the Sum func statement work 
essentially like AB AFL but I don't understand the use of .5 in
the Cross statement or the 10 in the ALERT statement.  I was not 
successful in finding online assistance in the Metastock langugage 
and if you have the time I would appreciate understanding how these 
specific statements work in Metastock  CROSS, SUM, and ALERT. 
If you can translate the attached it would be greatly appreciated as 
well;  or if you can point me to an on line source of the Metastock 
language.

I was trying to see if there was an idea or two that would help me 
in End of Day trading the ETFs in confirming breakouts.  This I know 
is for FOREX trading hence the 10 ticks statement. 

Thanks in advance 
Joe Landry
