//declare a variable to store individual currency strength int EUR = 0; //declare an array to store symbol values double eurTOgbp[]; //storing EUR values in array ArrayFill(eurTOgbp,0,1,EURGBP); ArrayFill(eurTOgbp,1,1,EURAUD); ArrayFill(eurTOgbp,2,1,EURNZD); ArrayFill(eurTOgbp,3,1,EURUSD); ArrayFill(eurTOgbp,4,1,EURCAD); ArrayFill(eurTOgbp,5,1,EURCHF); ArrayFill(eurTOgbp,6,1,EURJPY); Compare the GBP Pairs to the EUR Pairs and store the results as an integer in the EUR variable for(int i=0; i<eurTOgbp[1]; i++) { if(GBPAUD > eurTOgbp[i]) { EUR++; } else if(GBPAUD<eurTOgbp[i]) { EUR--; Print(EUR);This is not working either. I get an error about array out of range but I'm telling my for loop to stop after it reads the first spot in the array so I dont understand what I'm doing wrong.

JavaScript is probably the worst language to learn mql. You'll want to pick up some C++ tutorials to learn programming concepts instead.This is not working either.

As far as your task you need to use an initialization list.
string symbols []={"EURUSD","EURGBP","...","..."};
I think I have narrowed down the problem to my first ArrayFill function. I dont know why it's wrong but I think it is. In my mind I'm putting the value of EURGBP into the "Zero Position" or the first spot in the array. I am missing something still.

Thank you I will try this approach.

I want to populate an array with currency pair values. Arrays are quite a bit different from Javascript I'm gathering. I'm totally new to programming and I took some online courses in Javascript to help prepare me to learn MQL4. I'm running into a snag with arrays. I dont understand the MQL4 documentation about arrays. The line of code below is incorrect. How would I make it correct? Everything I find in the documentation only shows arrays with a number between the brackets. like this "int someArray[50]". What am I missing?
double eurPairs[EURGBP, EURAUD, EURNZD, EURUSD, EURCAD, EURCHF, EURJPY];
