Introduction
Astro Scalper EA is a precision-engineered Expert Advisor designed exclusively for MetaTrader 4. It specializes in ultra-short-duration scalping on gold (XAUUSD), combining automated trade execution with tight risk and entry controls.
Strategy Overview
The EA aims for rapid profits—typically around three pips per trade—executed in environments with ultra-low spreads (under 4 pips). It only operates during predetermined server-time windows (commonly between 02:00 and 23:00), avoiding rollover and high-volatility periods. Trade entries require strict conditions: low spread, minimum pip separation between orders, and limited trade frequency to ensure high-quality setups.
Core Features
Risk and Lot Management
- Default operation uses a conservative fixed lot size of 0.01
- Optional risk modes include percentage-based risk per trade (e.g. 0.1% of account balance) and balance-scaled lot sizing
- Drawdown controls (either fixed-value or percentage thresholds) can be enabled to halt activity when risk limits are reached
Profit Targets and Trailing Logic
- Typical take-profit is set at approximately 30 points (3 pips)
- A trailing stop initiates once a trade reaches about 5 points (0.5 pips) in profit and follows at roughly 20 points (2 pips), locking gains while allowing favorable moves
Operational Controls
- Enforces minimum pip distance (PipsStep ~3.5 to 5 pips) between trades to prevent stacked entries
- Incorporates a fast refresh interval (around 50 milliseconds) for responsive execution and real-time display updates

Recommended Environment
Broker Selection
To achieve optimal performance, the EA requires an ECN or raw-spread broker offering ultra-low spreads on XAUUSD. High spread or slippage environments can significantly impair results.
Account Setup
- Functional on accounts starting from around $100, though preferred initial capital is $500–$1,000 for smoother trade sizing and risk compliance
- Leverage recommendation typically ranges from 1:100 to 1:500 depending on broker and account size
- Use of a VPS is advised to maintain stable uptime, low latency, and consistent EA operation
Limitations
- Supports only MetaTrader 4; it is incompatible with MetaTrader 5 or other platforms
- Designed specifically for XAUUSD (gold); performance on other currency pairs or instruments is not guaranteed unless explicitly configured
- Results are contingent upon broker execution quality; poor spread or slippage can reduce profitability
- Advanced features like drawdown limits must be manually enabled; default settings may leave these safeguards off
