Error in WebRequest - Code 4006 - "Invalid Array Access"

New comment
 

I am trying to create an expert advisor that will fetch data ( JSON format including "Price", "Value" and "Timestamp" ) from my web service and i want it to display that data in the form of a line chart in my MT5 Terminal. I am extremely new to MQL5 and 99% of this code was written by AI but I need to complete this project and I can not understand where the problem is within my code. I keep getting the errors mentioned in the subject through all the debug statements I implemented. I am attaching my code below, any help would be appreciated.

I am using MQL5 and JAson.mqh Library.

    ChatGPT (the worst), “Bots Builder”, “EA builder”, “EA Builder Pro”, EATree, “Etasoft forex generator”, “Forex Strategy Builder”, ForexEAdvisor (aka. ForexEAdvisor STRATEGY BUILDER, and Online Forex Expert Advisor Generator), ForexRobotAcademy.com, forexsb, “FX EA Builder”, fxDreema, Forex Generator, FxPro, “LP-MOBI”, Molanis, “Octa-FX Meta Editor”, Strategy Builder FX, “Strategy Quant”, “Visual Trader Studio”, “MQL5 Wizard”, etc., are all the same. You will get something quick, but then you will spend a much longer time trying to get it right, than if you learned the language up front, and then just wrote it.

    Since you haven't learned MQL4/5, therefor there is no common language for us to communicate. If we tell you what you need, you can't code it. If we give you the code, you don't know how to integrate it into yours.

    We are willing to HELP you when you post your attempt (using Code button) and state the nature of your problem, but we are not going to debug your hundreds of lines of code. You are essentially going to be on your own.
