Hi, I''m new to Easy Language and need help to understand the following pre-built Keltner channel Buy signal in Multicharts, which unhelpfully has no notes to explain what's going on! So from what I can tell it looks for a channel breakout (price crosses above the upper band) and then sets a buy stop order on the next bar at high + 1 tick. But...

 

Code

[IntrabarOrderGeneration = false] inputs: Price( Close ), Length( 20 ), NumATRs( 1.5 ) ; variables: var0( 0 ), var1( 0 ), var2( 0 ), var3( false ), var4( 0 ) ; var0 = AverageFC( Price, Length ) ; var1 = NumATRs * AvgTrueRange( Length ) ; var2 = var0 + var1 ; condition1 = CurrentBar > 1 and Price crosses over var2 ; if condition1 then begin var3 = true ; var4 = High ; end else begin condition1 = var3 and ( Price < var0 or High >= var4 + 1 point ) ; if condition1 then var3 = false ; end; if var3 then Buy ( "KltChLE" ) next bar at var4 + 1 point stop ;

...what I don't understand is:

1) why the code doesn't simply use condition1 to initiate the Buy order i.e.

 

Code

condition1 = CurrentBar > 1 and Price crosses over var2 ; if condition1 then Buy ( "KltChLE" ) next bar at var4 + 1 point stop ;

2) what's going on in the "else" portion of the if else statement? It seems to be saying, if var3 is true, and either price is below the mid line (var0) or there is a new high, then var3 is false... very confused and I'm not sure why it is necessary.

3) why is "condition1" used twice to define different conditions. In terms of best practice should they not be condition1 and condition2?

4) why var4 is defined within condition1, not outside of it? Does it make any difference?

Really quite confused by this code and appreciate any help

I think the key to understanding this bit of code is that it saves certain values
at a point in time. I.e. it saves what the High is when the condition was last met
and then uses that later on.

Pseudo code would be

Get SMA + ATR (Keltner Top)

if price crosses over the Keltner then save condition true (var3) & save this high value (var4)
else
recheck everything ->
-> if in the past var3 was set to true, but now Close < SMA or High > than prev high when condition was met
then set var3 to false again

if var3 = true then buy at High + 1 point

//--------
I think theres some logic missing in the else part that's not right but I suspect what the person
was trying to do was something like -> a signal happens and then there's a pullback afterwards or
price keeps heading higher then do the following [but not finished coding]
