how do i fix this error 'SymbolInfoDouble' - no one of the overloads can be applied to the function call could be one of 2 function(s)

// Define input parameters from the original code

1.     void OnTick() {
           double currentFastMA = iMA(_Symbol, 0, FastMA, 0, MODE_SMA, PRICE_CLOSE);
           double currentSlowMA = iMA(_Symbol, 0, SlowMA, 0, MODE_SMA, PRICE_CLOSE);

   They all (including iCustom) return a handle (an int). You get that in OnInit. In OnTick/OnCalculate (after the indicator has updated its buffers), you use the handle, shift and count to get the data.

2. Stop using ChatGPT.
             Help needed to debug and fix an AI EA - Trading Systems - MQL5 programming forum #2 (2023)

   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.

   ChatGPT	Even it says do not use it for coding. *  Mixing MT4 and MT5 code together. Creating multiple OnCalculate/OnTick functions. OnCalculate returning a double. Filling buffers with zero in OnInit (they have no size yet). Setting buffer elements to zero but not setting Empty Value to correspond. Calling undefined functions. Calling MT4 functions in MT5 code. Sometimes, not using strict (MT4 code). Code that will not compile. Creating code outside of functions. *  Creating incomplete code. *  Initialization of Global variables with non-constants. *  Assigning a MT5 handle to a double or missing the buffer and bar indexes in a MT4 call. *  Useing MT4 Trade Functions without first selecting an order. *  Uses NULL in OrderSend. *
   bot builder	Creating two OnInit() functions. *
   EA builder	Counting up while closing multiple orders. Not useing time in new bar detection. Not adjusting for 4/5 digit brokers, TP/SL and slippage. *  Not checking return codes.
   EATree	Uses objects on chart to save values — not persistent storage (files or GV+Flush.) No recovery (crash/power failure.)
   ForexEAdvisor	Non-updateing global variables. Compilation errors. Not checking return codes. Not reporting errors.
   FX EA Builder	Not checking return codes. Loosing open tickets on terminal restart. No recovery (crash/power failure.) Not adjusting stops for the spread. *  Using OrdersTotal directly. Using the old event handlers.

   Perhaps you should read the manual. The second parameter is a ENUM_SYMBOL_INFO_DOUBLE
