Easylanguage subroutines

August 18th, 2011, 11:43 AM

Hello

How can I create and use subroutines with Easylanguage?

I need to reuse code many times and it would be nice to convert it as a subroutines and call it several times.

Somebody might advise me to use functions but I need that those subrotuines also contain orders (sell, buy, stop loss...) and only strategies are allowed to send orders.

Thanks.

For example, but It could more difficult

/// Subrutine1

Code

If close>High[1]+30 then begin
	Buy("entry1") next bar at market;
	Sell("exitstop") Next Bar Low-30 stop;
end;

// Main code

Code

if condition1 then call subroutine1;
if condition2 then call subroutine2;
if condition3 then begin
	call subroutine1;
	call subroutine2;
end;

You can define your subroutines as methods.

Code

Method double Subroutine1(double dou) begin
    if t=1200 then Buy this bar;    
    Return dou*2;
end;    

Method double Subroutine2(double dou) begin
    if t=1300 then sell this bar;    
    Return dou/2;
end;   

value1=Subroutine1(c);
value2=Subroutine2(c);

that should only work on TS9 right? I dont recall 8.x having methods, then again... I am not an expert on EL...

I use Multicharts.
I can't find any documentation on this at powerlanguage.chm nor EL_FunctionsAndReservedWords_Ref.pdf help files.
Could you tell me where can I find it, please?

Can these subroutines send "Sell" and "Buy" orders or they are just functions?

I'm not sure which version introduced the functionality. Give it a try and see.

As far as I know, MultiCharts does not support this as of yet. TradeStation is able to send orders from the subroutines.

Very useful.

When will @MultiCharts support this? (hoping Stan will respond).
