EA Performance and Trading Logic
📌 The Expert Advisor (EA) demonstrated a 90% win rate on both short and long trades over 1.5 years, processing 680,000 trades in just over 500 days.
📈 Starting with a balance of €1,000, the backtest showed an ending balance of €1.5 billion (noting backtest results are highly unrealistic due to zero slippage/execution delay).
⚙️ The core logic involves placing two stop orders at a fixed distance; if one fills and profits, the stop loss trails aggressively, and scaling in occurs by placing a new order in the same direction.
⚠️ High order frequency leads to warnings or bans from brokers; efficient trading sessions must be limited, potentially to 10-15 minutes per day, with potential returns of 2.5% in 10 minutes.

MQL5 Coding Structure and Variables
🛠️ The coding process began by setting up the basic MQL5 structure: global variables, initialization, deinitialization, and the `OnTick` function, using the included CTrade library for operations.
🔗 Key input variables were established, including settings for lot sizing (fixed vs. percentage of balance/equity/margin) and order parameters based on spreads (e.g., Order Distance, Stop Loss, Trailing Cost).
🔄 The Initialization function sets crucial broker parameters like minimum/maximum lot sizes, stop levels, and freeze levels, adjusting internal variables accordingly.
⏱️ The OnTick function manages commission/spread adjustments, historical data management (spread array), and complex calculations for dynamic order adjustments and stop-loss trailing based on defined parameters.

Order Management and Modification Code
🔄 The code iterates through existing pending orders (Buy Stop/Sell Stop) to check if they are within the allowed trading time window and if current spreads exceed the maximum allowed threshold, deleting them if conditions are not met.
🏃 Trailing logic for open positions dynamically calculates the required trailing distance based on price movement, minimum required stop distance, and user-defined factors (like `max trailing limit`).
🎯 New orders (Buy Stop/Sell Stop) are generated only after confirming margin availability, ensuring the calculated lot size adheres to broker minimums, and respecting minimum order intervals between trades.

Key Points & Insights
➡️ The EA's high-frequency trading approach (680,000 trades in 500 days) requires extreme caution regarding broker limits and risk of being banned.
➡️ Modifications planned include switching scaling-in logic to only occur when existing positions are already in profit, moving away from scaling in while the initial stop loss is still active.
➡️ Users are encouraged to test different settings and share successful modifications with the community, as the provided code is a foundation derived from an obscure source.
➡️ Testing will focus on MT5 due to its lower minimum lot size (0.1 vs. 1.0 on MT4 for US30), making realistic low-capital testing more manageable.
