The error I found in the journal was:

I'm not sure but does the error mean that the indicator doesn't have the array values passed [1] ? So, when I try to look up [2] or [3] etc, they were never created? I haven't been able to get in touch with the guy who wrote it for me so I don't know whether or not it goes farther than just candle 1. I assumed it did but maybe he didn't know that's what I meant. I can't tell by looking at the code. Sorry to post so much. I just don't know what is relevant and what isn't. I thought I put all the relevant code in the first post.

The number "(151,41) " in the error message, means the error is at line 151, at character position 41. So you will have to tell us where exactly is line 151 in your code.
Alternatively, which I believe will be easier and better for those helping you, is for you to instead of pasting your files as text, is to add them to a post as a true file attachments with their original names so the user can download and compile and test themselves to be able to see what is happening.

Sorry. That makes sense. I'll attach them here.
I thought I figured it out for a minute. Nope. lol I'm lost. I'd appreciate any help from anyone.
Unable to compile "Jay_Divergences_EA.mq4", given that there is at least one file missing; namely "CustomFunctions01.mqh".
I have found at least one location that will generate an Array out of Range error:
You are declaring arrays of size 3, but then in the loop you are incrementing variable "c" up to 5 (0 to 4) which is beyond the range of the arrays size of 3 (0 to 2).
EDIT: Please note that the following code was lifted from your "Jay_Divergences_EA.mq4" file you attached in a previous post and not the code text in previous posts.
//The Price value at swing points. double H_Price[3]; double L_Price[3]; double H_Macd[3]; double L_Macd[3]; //The time value at swing points. datetime H_Price_T[3]; datetime L_Price_T[3]; datetime H_Macd_T[3]; datetime L_Macd_T[3]; //Looking for Highs on the Zig zag Price! (Creating the H_Price and H_Price_T values) int c=0; double aux=0; for(i=1; i<Bars; i++) { aux=iCustom(NULL, 0, "ZigZag_JayDasilva", "", fast_ema_period, slow_ema_period, signal_period, 1, i); if(aux!=0) { H_Price[c]=aux; H_Price_T[c]=Time[i]; c++; } if(c==5) break; }
Please note that the files you provided do not match in content to the code text that you have shown in previous posts!
So, we are left not knowing which ones you are actually using in your tests.
Please be consistent and provide the correct information, or else we will be unable to help!
Also assuming the array size declarations so far given, then the following areas are also prone to Array out of Range errors:
if(H_Price_T[1] < L_Price_T[1]) // When the variable has the _T it represents the candle number. { wave1 = H_Price[1] - L_Price[1]; // Without the _T it represents the price. wave2 = H_Price[2] - L_Price[1]; wave3 = H_Price[2] - L_Price[2]; wave4 = H_Price[3] - L_Price[2]; wave5 = H_Price[3] - L_Price[3]; avgWave = ((wave1 + wave2 + wave3 + wave4 + wave5)/5)*pipValue; //pipValue = 100 or 10,000 depending on the pair Comment("Average Wave: " + avgWave + " pips"); } else { wave1 = H_Price[1] - L_Price[1]; wave2 = H_Price[1] - L_Price[2]; wave3 = H_Price[2] - L_Price[2]; wave4 = H_Price[2] - L_Price[3]; wave5 = H_Price[3] - L_Price[3]; avgWave = ((wave1 + wave2 + wave3 + wave4 + wave5)/5)*pipValue; Comment("Average Wave: " + avgWave + " pips"); //+------------------------------------------------------------------+

int j=iBarShift(NULL,0,PrevBullish,false); int k=iBarShift(NULL,0,PrevBearish,false); Peak_Bar=iLowest(NULL,0,MODE_LOW,k-j,j);
There are k-j+1 bars between j and k.

For a new bar test, Bars is unreliable (a refresh/reconnect can change number of bars on chart), volume is unreliable (miss ticks), Price is unreliable (duplicate prices and The == operand. - MQL4 programming forum.) Always use time.

Really new to coding. MQL4 is the only thing I'm learning. Someone wrote me a code so that I could play with and experiment with some ideas I have. They did the hard stuff and created variables that represented the swing highs and swing lows on the price chart (H_Price would be a swing high price and H_Price_T would be the candle number) This way I can simply use those variables to find divergence or wave sizes and simple things like that. Well I'm trying to write a small part (excuse the inefficient coding) to simply calculate the average size of the last 5 waves. If I remove the section of code that I'm sharing here, then everything works fine. These variables have been used in other parts of the code and worked. I don't understand what I've done differently. The divergence example is the part that works fine. When I add the code underneath it to calculate the average wave size then I get the error. I would appreciate any help. Please speak to me in layman's terms - I'm practically a baby when it comes to this stuff.
Thank you in advance!
