Noob MQL4 help needed to understand this array

[Agent86]

Hi, coders

Would anyone care to educate me on arrays slightly
Or perhaps I'm having more trouble understanding this loop as it pertains to this array.

int i=Bars;


#property copyright "Unfinished POS by Agent86"
double v1[];

double v2[];

double val1;

double val2;


int start()

{



while(i>=0)

{

val1=iFractals(NULL, 0, MODE_UPPER,i);



if (val1 > 0)

{

v1[i]=High[i];



}

else

{

v1[i]=v1[i+1];

}





val2=iFractals(NULL, 0, MODE_LOWER,i);



if (val2 > 0)

{

v2[i]=Low[i];

}

else v2[i]=v2[i+1];



i--;



}


return(0);

}

It's a basic fractal, and yet I can't seem to refer to any elements in the array.

I want to be able to increment i++ somehow and Print (v1[i]); or print the previous value prior to the 0 or EMPTY_VALUE.
If I'm even going in the right direction with this.

I'm having trouble.
Print (v1[i]): always == 0 and prints 0
I sort of understand because it's actually looping down to -1 which == 0

How and where might I put the Print statements so I can see whats going on ?
I've tried multitudes or methods and re-initialized i=0 to attempt and alternate loop so that I might refer to v1[i] elements but all attempts have failed.

Basically I want to view the previous fractals or mark them as A high, B low etc. for possible future use in an ABCD scheme type of EA
For now, mainly I want to Print v1[i] so that I can see what it's doing.
Perhaps I might design something to select a Previous Fractal such as A_high and/or B_low or some such scheme.

Am I on the wrong track with this ?

Please advise
Thanks
