Hi, I'm new to Easylanguage and struggling with programming the Donchian (or Price Channel) as I need it.

I'm looking to either add the displace functionality to the Donchian code I already have (further down in this page), or adding the MEAN to the existing code for the Price Channel. I need the MEAN and the displace option and neither the Donchian or Price Channel have both.

I'm guessing it's easier to add the MEAN to the Price Channel code (below). I've added a var2 and plot3 but can't get anything to compile. Any help very gratefully appreciated.

Thanks
TMT


inputs: Length( 20 ), Displace( 0 ) ;
variables: var0( 0 ), var1( 0 ) ;

var0 = Lowest( Low, Length )[1] ;
var1 = Highest( High, Length )[1] ;

condition1 = Displace >= 0 or CurrentBar > AbsValue( Displace ) ;
if condition1 then
begin
Plot1[Displace]( var1, "UpperBand" ) ;
Plot2[Displace]( var0, "LowerBand" ) ;
Plot3 ((var1 +var0)/2, "MEAN" );

if Displace <= 0 then
begin
condition1 = Low crosses under var0 ;
if condition1 then
Alert( "Price making new low" ) ;
condition1 = High crosses over var1 ;
if condition1 then
Alert( "Price making new high" ) ;
end ;
end ;

Hi,

I tried to insert the Function that I found in this thread, but Tradestation reports this error:
"A value was never assigned to user function"

if someone can solve the problem, I thank you in advance.

................................................................

Function:

// Ported to MultiCharts by Big Mike, https://nexusfi.com/

// Dec 23 2010



inputs:

period (NumericSimple),

myMid (NumericRef),

myUpper (NumericRef),

myLower (NumericRef);



myUpper = Highest(H, period);

myLower = Lowest(L, period);

myMid = (myUpper + myLower) / 2;

Here is what I have.
Hope this helps.

Thank you, but unfortunately Tradestation 8.2 cannot read the .ELD files of the higher versions (9 and 10, see image).
If you can insert the Function of the Donchian Channel in text format (txt).
Thank you very much.

Functions typically need to always return "something", so for the Donchian code above, simply add...

 

Code

DonchianChannel = myMid;

...to the end of the code (assuming the name of the function is "DonchianChannel"; if not, simply replace the variable name with the name of the function itself).

The 3 (NumericRef) output variables are generally what you're using anyway so this is just to satisfy the compiler.

For Fu510n: thank you very much.

Here there is a Trading System in Easylanguage with the Donchian Channel:
