Hello,
In your formula an error appears regardless of Zig().
Did you actually READ what error message says?
It says "variable x used without being initialized".
Error says it all. You are trying to use variable ('x') that was NEVER defined.
Before any use, you need to assign VALUE to the 'x' variable, like this:
x = something;
Do not try to "reduce array manipulation" because you lack basic understanding
of AFL.
The code that you have presented does nothing except to ADD complexity.
You will gain *nothing* this way.
Best regards,

Hello,
I had anyone else experienced staticvarset generating error an error condition
with the use of the zig function ?
I have been trying to work around this issue - but am finding that in order to reduce array manipulation - i would like to set static variables - but this
does not seem to work with call of the zig function anywhere in the code.
I have attached the sample code and a description of the irregularity with
amibroker. This has been prevalent in 5.20 and is still an issue with 5.30.
Have i overlooked anything ?
Thanks and regards
James
p/s: this was tested on the sample data (^DJI Daily) that comes with the
default amibroker install.
x = Cum(1);
//-----------------------------------------------------------------------------
// In this example "svar" holds the last value of x when var3[i] == 1.
// Note: this changes with the displayed data.
// When the "Causeserror" array is not commented out - amibroker no longer
// references the last displayed value.
//-----------------------------------------------------------------------------
//Causeserror = Zig(High, 0.1); // <= remove "//" and the functionality changes,
Var1 = MA(*L*, 5);
Var2 = MA(*H*, 15);
Var3 = Cross(Var1, Var2);
Plot (Var3 *1000, "va3", *colorRed*);
* *
*for* (i=0; i<*BarCount*; i++)
{
* *
*if* (Var3[i] == 1)
{
StaticVarSet("svar", x[i]); // Last "x" value when var3[i] == 1
}}
Plot(StaticVarGet("svar"), "svar", *colorBlue*);
