Tarea técnica

Hello. I need an expert MQL4 developer to create a professional Gold (XAUUSD) Grid/Martingale EA for MetaTrader 4 (MT4). 

This project requires high reliability, a clean visual dashboard, strict web-based license security, and native language input configurations.

====================================================================
1. CORE TRADING LOGIC (XAUUSD, M1 Timeframe)
====================================================================
- The EA executes bi-directional (Buy/Sell) grid trading depending on input toggles.
- Initial Entry: Opens the first trade with 'StartLot' size.
- Grid Layering: If the market moves against the open position, the EA opens consecutive entries at fixed intervals defined by 'GridDistancePoints'.
- Lot Multiplier: The lot size multiplication factor is controlled by 'LotMultiplier'. (If set to 1.0, it operates as a standard fixed-lot grid).
- Max Protection: Open orders in a single direction are strictly limited by 'MaxOrdersPerDir'.
- Basket Take Profit: Once multiple orders are active, the EA calculates the combined break-even price and applies a unified Basket TP target in points ('TakeProfitPoints') from the average price matrix.
- Basket Stop Loss: If the cumulative floating drawdown reaches 'BasketSLAmount' in account currency ($), the EA must immediately hard-close all active positions to protect equity.

* SPECIAL NOTE FOR BACKTESTING/LOGIC ANALYSIS: 
Please ignore the manual over-trading anomaly observed between 10:14:42 and 10:20:00 on May 29, 2026, in any user-provided statement histories. It was a manual UI test error. The core algorithm must strictly follow the automated rules mentioned above.

====================================================================
2. SECURITY & LICENSE MANAGEMENT (Web Authentication)
====================================================================
I am running a subscription-based business. The EA must include a Web License Security layer using Google Sheets via WebRequest().
- On Initialization (OnInit), the EA must query a Google Sheet CSV export URL.
- The Google Sheet contains Authorized MT4 Account Numbers (Column A) and Expiry Dates (Column B).
- If the current terminal 'AccountNumber()' is NOT found in the sheet, or if the current time 'TimeCurrent()' has passed the Expiry Date, the EA must:
  a) Display a large red text on the chart screen: "LICENSE ERROR: Unauthorized Account or Subscription Expired!"
  b) Trigger an Alert popup dialog box.
  c) Forcefully unload itself from the chart using 'ExpertRemove()'.
- If the WebRequest fails entirely (e.g., no internet connection), the EA must lock itself and remove itself for safety.

====================================================================
3. USER INTERFACE (UI) & GRAPHICAL DASHBOARD
====================================================================
- The EA must draw a sleek, modern visual panel overlay on the chart screen.
- It must dynamically display: Account Balance, Equity, Margin Level, Open Buy/Sell Lots, Net Floating Profit/Loss, and Subscription Status.
- Dashboard position and text styling must be adjustable via input variables.

====================================================================
4. MANDATORY INPUT PARAMETERS (With Native Comments)
====================================================================
To allow customizable setups directly via the MT4 properties window, you must implement the inputs EXACTLY with the specific native Korean comments provided below. MT4 uses these comments as labels, which is mandatory for my operations.

input string   _heading0           = "======= GOLD GALE EA ======="; // [ GOLD GALE EA ]
input int      MagicNumber         = 123456;                         // 매직 넘버 (Magic Number)

input int      GridDistancePoints  = 700;                            // 추가 진입 간격 (Grid Distance Points)
input int      MaxOrdersPerDir     = 5;                              // 한 방향당 최대 진입 횟수 (Max Layers)
input string   _heading5           = "--- [5] 청산 모드 및 리스크 관리 ---";
input bool     UseBasketTP         = true;                           // 전체 평단가 기준 바스켓 익절 사용

input int      ADX_Period          = 14;                             // ADX 기간 설정
input int      ATR_Period          = 14;                             // ATR 기간 설정
input double   ADX_Threshold       = 25.0;                           // 추세/횡보 판단 기준값
input string   _heading7           = "--- [7] 대시보드 UI 디자인 ---";
input string   PanelPosition       = "Bottom_Right";                 // 패널 위치 (우측하단 기본)
input int      Panel_X_Offset      = 50;                             // 가로 여백 (X 오프셋)
input int      Panel_Y_Offset      = 30;                             // 세로 여백 (Y 오프셋)
input int      FontSize            = 9;                              // 글자 크기
input string   FontName            = "Consolas";                     // 글꼴 이름

====================================================================
5. INTELLECTUAL PROPERTY & DELIVERY TERMS
====================================================================
- 100% Full Source Code Delivery Required: You must provide both the compiled file (.ex4) and the fully unencrypted source code file (.mq4) with all comments preserved. Deliveries with only the .ex4 file will be rejected immediately.
- Clean Code Practices: Ensure proper decimal and point-digit tracking automatically for Gold spot symbols (e.g., auto-detecting 2-digit or 3-digit quote environments).
- Absolute Confidentiality: You are strictly prohibited from reselling, redistributing, or reusing this code or logic for other commercial projects.

Thank you. I look forward to working with a skilled professional. Please provide your realistic cost estimation and delivery timeline.
