"Once" reserved word

BD. · Postby **BD.** » 10 Feb 2024

Why is this behavior happening? "once" setting condition to true then changes reversed back to false by itself, same with numeric variable. It looks like it only happens when "once" condition evaluates to true on the last bar no matter which way - by reserved word or function or bar number.

Code: Select all

vars:
		cond1(false),cond2(false),cond3(true),
		val1(0),val2(0);

once (LastBarOnChart) begin
			cond1=true; 
			cond2=true;
			val2=realBarNumber;
	end;
	 
once (cond1) begin
	print("I work"); 
			print("cond1: ",cond1," cond2: ",cond2," Bar Num: ",val2); 
	end;

if cond1 then print("I still work");

if d=1230323 and t>1415 then print(realBarNumber);

Code: Select all

I work
cond1: TRUE cond2: TRUE Bar Num: 15895.00
I still work
15895.00 value: 15895.00
15895.00 value:    0.00
15895.00 value:    0.00
15895.00 value:    0.00
15895.00 value:    0.00
15896.00 value:    0.00

Hello,

Where do you see cond1 change back to false?
The behaviour is not reproduced on our end with the example you posted. The issue might be with your realBarNumber function.

Code: Select all

vars: cond1(false), cond2(false), val2(0);
once (LastBarOnChart) 
begin
	cond1 = true; 
	cond2 = true;
	val2 = Symbol_CurrentBar;
	print(" 1 once ", "cond1: ", cond1, " cond2: ", cond2, " Bar Num: ", val2); 

end;
	 
once (cond1) 
begin
	print("I work"); 
	print(" 2 once ", "cond1: ", cond1, " cond2: ", cond2, " Bar Num: ", val2); 
end;

if cond1 then print("I still work");

print(Symbol_CurrentBar);

Code: Select all

1012.00
1013.00
1014.00
1015.00
 1 once cond1: TRUE cond2: TRUE Bar Num: 1016.00
I work
 2 once cond1: TRUE cond2: TRUE Bar Num: 1016.00
I still work
1016.00
1016.00
1016.00

this happened in SIM trading. I've sent an email with details.

Code: Select all

realBarNumber=BarNumber+MaxBarsBack;
