Scalper 1 – Higher Timeframe Trend Fully Synchronized, High-Precision Time Filter Scalping

■ Overview of this EA

“Scalper 1” is an MT5 (MetaTrader 5) exclusive automated trading system (EA) that analyzes the long-term trend direction to the extreme and targets pinpoint entry timing.

The greatest strength is that it features completely independent logic (calculation engine) for “buy” and “sell”. Unlike typical EAs that reuse a single indicator setting, the internal values are completely fixed to fit the characteristics of both bullish and bearish markets. It is designed so that users can deploy it from day one without struggling with complicated settings, and the developer’s optimal performance is realized immediately.

Furthermore, it includes the most important feature for a commercial EA: “safety design (excess margin check function)” as standard. The system calculates the account’s capital in real time, preventing errors from overly aggressive orders, thereby protecting valuable assets while operating safely.

■ Five carefully selected logics included

This EA will enter with confidence only the moment all of the following five indicator conditions are perfectly aligned.

1. 【Weekly Filter】Confirms the long-term market “direction”.

2. 【Daily Filter】Determines which way the medium-term current momentum is pointing.

3. 【1-hour MACD Filter】Accurately captures the trend initiation from the recent moving average deviation (lagging line).

4. 【Execution-minute Bollinger Bands】Measures market “overextension (volatility)” and attracts to the optimal timing for entry.

5. 【Profit-guarding Trailing Stop】After entry, monitors the market every 10 seconds. Once profit is on the table, automatically lifts the exit line to ensure profits are retained—a reliable exit feature.

■ Safe and convenient features

• Excess Margin Auto-Check Function (New)Immediately before placing an order, the system strictly calculates the available purchasing power of the account. If the position size is too large relative to funds or if margin is insufficient due to sudden market moves, it automatically skips the order to prevent unnecessary errors (reducing a flood of log entries).

• Compounding Operation (Auto Lots) FunctionImplements a compounding feature that automatically steps up to optimal lot sizes as the account balance grows. Starts with a small amount and aims for reliable asset growth. (Fixed lots operation is, of course, also possible)

• Maximum Spread LimitationAutomatically avoids dangerous entries during times of abnormally wide spreads, such as at significant news releases or early morning.

■ Parameter Settings Screen

Settings items are carefully limited to what is necessary for operation. Internal optimization and safeguarding of complex logic ensures that even beginners can use it with confidence without confusion.
