Golden Trader

1. EA Description (GOLDEN TRADER)

The GOLDEN TRADER EA v6.3 is an automated trading robot designed to execute a fully hedged trading strategy—opening simultaneous Buy and Sell orders of equal lot size on the same symbol. The core philosophy is to lock in a fixed risk per trade (via a user-defined risk percentage) while aiming for a consistent 1:2 Risk-to-Reward ratio (Stop Loss 300 pips / Take Profit 600 pips by default). It features robust money management (fixed or dynamic lot sizing), real-time spread control to avoid trading during high spreads, an advanced trailing stop mechanism to protect profits, and a clean real-time dashboard. This EA is particularly suitable for traders looking to capitalize on ranging or volatile markets while strictly controlling margin usage and avoiding over-trading.

3. Optimizing Settings for Forex & Metal Pairs

Below are recommended input parameter configurations tailored for different asset classes. You can run these settings in the MT4 Strategy Tester to find the best performance.

A. Forex Pairs (e.g., EURUSD, GBPUSD, USDJPY)

Parameter Recommended Value Notes
UseAutoLotSizing true Ensures proper risk management based on balance.
RiskPercentPerLeg 0.5% – 1.0% Lower for higher volatility pairs (e.g., GBPUSD = 0.5%).
StopLossPips 200 – 300 Use 200 for H1, 300 for M5/H1.
TakeProfitPips 400 – 600 Maintain 1:2 R:R (e.g., SL 200, TP 400).
MaxAllowedSpread 30 – 50 Major pairs usually have low spreads; use 30 for EURUSD, 50 for GBPJPY.

TrailingStartPips 100 – 150 Start trailing once profit reaches this level.
TrailingStepPips 30 – 50 Minimum distance to keep behind current price.

MaxAllowedSpread  25

RiskPercentPerLeg 0.5% Reduce risk for metals due to large stop losses.
ManualLotPerLeg 0.01 (if auto off) Start with minimum positions.

🔧 General Optimization Tips

  1. Tester Mode: Use "Every tick" for accurate trailing stop testing.

  2. Testing Period: Test over at least 1–2 years of data to account for different market conditions.

  3. Spread Impact: Use "Spread" as a variable in the tester (e.g., 10–30 for forex, 30–60 for gold) to simulate real-world conditions.

  4. Balance: Ensure your initial deposit is sufficient to cover margin requirements (e.g., at least $5,000–$10,000 for 0.01 lots on Gold).

  5. Optimization Criteria: When running optimization, prioritize "Profit Factor" and "Max Drawdown" —don't just look for the highest net profit.

시장 반전 경고 EA는 동일한 이름(여기에서 사용 가능)의 지표에 의해 구동되며 시장 구조 변화를 기반으로 거래됩니다. EA는 기본적으로 지표에서 시장 반전 경고를 보낼 때마다 거래를 수행하고 EA 설정에서 설정한 조건 및 필터를 기반으로 해당 경고를 거래합니다. 가격이 현재 추세 방향으로 움직일 때 지지 직사각형을 그리고 가격이 급격하게 반전할 때 거래되고 시장 구조의 변화 또는 반전의 재시험을 알립니다. 표시기 페이지에서 자세히 알아보십시오. 이 설명에서 다루기에는 너무 많은 설정과 가능성이 있으므로 모든 설정이 포함된 블로그 게시물과 이 블로그 게시물에서 자세히 설명하는 비디오가 있습니다.  https://www.mql5.com/en/blogs/post/745502 위의 해당 게시물을 읽고 비디오를 시청하면 EA가 얼마나 강력한지 알게 될 것입니다. 이 블로그 게시물에서 시작하는 데 도움이 되는 몇 가지 좋은 설정 파일과 전략을 볼 수 있습니다.  https://w

Have you ever wondered why most expert advisors are not effective in live trading, despite their perfect backtest performance? The most likely answer is Over-fitting . Many EAs are created to ‘learn’ and adapt perfectly to the available historical data, but they fail to predict the future due to a lack of generalizability in the constructed model. Some developers simply don't know about the existence of over-fitting, or they know but don't have a way to prevent it. Others exploit it as a tool

시장은 변합니다. EUR MACHINE PRO도 시장에 맞춰 변화합니다. 모든 상황에 하나의 전략만 사용하는 것이 아닙니다. 하나의 신호도, 하나의 고정된 규칙 세트도 아닙니다. EUR MACHINE PRO는 먼저 현재 시장이 어떤 상태인지 판단한 뒤, 그에 맞는 트레이딩 로직을 선택합니다. 횡보장? 추세장? 낮은 변동성? 높은 변동성? 시장 상태에 따라 서로 다른 모델, 서로 다른 진입 조건, 그리고 서로 다른 포지션 관리 방식이 사용됩니다. 이것이 많은 전통적인 Expert Advisor와 다른 점입니다. 시장이 이미 변했는데도 같은 공식을 계속 적용하는 방식이 아닙니다. 특별 출시 가격 EUR MACHINE PRO 출시 가격 — $390. 이 가격은 첫 10명의 구매자에게만 제공됩니다. 첫 10개가 판매된 후에는 제품 가격이 인상됩니다. 주요 장점 학습된 Machine Learning 모델 — 모델 로직은 과거 시장 데이터를 기반으로 사전에 학습되었으며 EA 내부에 직접 내
