TR : EZL questions about BarNumber and multiple Data

["Lhermie" <philippe.lhermie@xxxxxxx>]

Hi folks,
 
1. Could you explain to me what’s the difference between :
 
If BarNumber <= 1 then begin…
 
And
 
If BarNumber = 1 then begin…
 
???
 
2. Why it is not recommended to write this:
 
Average(Close of Data2, 20)
 
Rather than
 
Average(Close, 20) of Data2
 
????
 
 
Regards,
Phil
