G'day Tomasz, "x" is defined below. I am sorry if i dont have the expert understanding of required to be proficient at coding with amibroker. But "x" is most definately defined. When the code is run - it runs as my original post states. It works well - as long as the line with "zig" is not called. Part of the reason that prompted me to use staticvarset / get is that i am running a high array count and would like to drop it significantly.

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.

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);
