Malaysian Support and Resistance

MetaTrader 5 Expert Advisor | Multi-Symbol Support & Resistance Trading with Trend-Based Logic

Overview

Classic SNR Breakout EA is a professional trading robot that identifies structural Support & Resistance levels using daily swing points and executes trades based on H1 price action relative to these levels. The EA applies dual logic: in an uptrend, it sells on H1 rejection below an SNR level; in a downtrend, it buys on H1 rejection above an SNR level. Breakout confirmations are also traded when the H1 close moves decisively beyond a level.

The EA scans up to 14 symbols simultaneously, automatically resolving broker-specific symbol names and suffixes.

This strategy is designed for traders who understand that structural levels can act as both support/resistance and breakout triggers, depending on market context.

How It Works

The EA analyzes daily close prices to identify swing highs and swing lows over a configurable lookback period. These swing points become structural Support and Resistance levels. The EA then monitors H1 candle closes relative to each SNR level and applies trend-based logic to determine trade direction.

Core Trading Logic

The EA does not simply trade breakouts in one direction. Instead, it evaluates price position and H1 close behavior:

This means:

• In an uptrend (price trading above an SNR level): If the H1 candle taps the level but closes below it, this signals rejection. The EA opens a SELL position.

• In a downtrend (price trading below an SNR level): If the H1 candle taps the level but closes above it, this signals rejection. The EA opens a BUY position.

• Breakout scenario: When price breaks through a level and the H1 candle closes beyond it, the EA trades in the breakout direction (BUY above resistance, SELL below support).

Signal Generation Process

Step 1: Daily SNR Calculation

• Scans daily close prices over the configured period (default 60 bars)

• Identifies swing highs (resistance) and swing lows (support)

• Clusters nearby levels within user-defined distance (default 50 pips)

• Levels are sorted and classified relative to current price

Step 2: H1 Confirmation (Dual Logic)

• Waits for an H1 candle to close

• The candle must "tap" the SNR level (low ≤ level ≤ high)

• Rejection Signal (Counter-Trend):

  • Price above level + H1 closes below level → SELL

  • Price below level + H1 closes above level → BUY

• Breakout Signal (Trend-Following):

  • H1 closes above resistance → BUY

  • H1 closes below support → SELL

Step 3: Pending Signal Creation

• When H1 confirms, a pending signal is created at the SNR level

• The EA waits for price to return within the entry zone (default 5 points)

• Pending signals are invalidated if price breaks through the level on subsequent H1 bars

Step 4: Precise Entry Execution

• When price returns to the SNR level ± entry zone, the trade executes immediately

• Stop loss is placed beyond the SNR level with user-defined buffer

• Take profit targets the next SNR level in the direction of the trade

• Partial profit taking closes 50% of the position at 50% of TP distance and moves SL to breakeven

Reversal Handling

When a new H1 confirmation contradicts an existing position direction, the EA automatically closes all positions of the opposite type before opening new ones. For example:

• If the EA has BUY positions and a new SELL signal is confirmed, all BUY positions are closed first

• This prevents position pile-up and follows the new market direction

Risk Management

Position Sizing

Lot sizes are calculated automatically based on:

• Account equity

• Risk percentage per trade

• Stop loss distance in pips

• Symbol-specific tick value and tick size

The EA also respects:

• Broker volume limits (min, max, step)

• Position volume limits per symbol

• Margin availability (prevents over-leverage)

Partial Profit Taking

At 50% of the distance to the take profit level:

• Half of the position volume is closed

• The remaining position's stop loss is moved to breakeven

• Original take profit target remains active

This locks in profits early while keeping runners open for extended moves.

Features

Dual Trading Logic (Breakout + Rejection)

The EA does not rely on a single market condition. It adapts to price behavior:

• Rejection trades: When price respects an SNR level and reverses, the EA enters counter-trend positions

• Breakout trades: When price violates an SNR level with conviction, the EA enters trend-following positions

This dual approach allows the EA to perform in both ranging and trending markets.

Automatic Symbol Resolution

The EA includes an extensive alias database covering:

• Indices: US30, US100, US500, DE30, UK100, JP225

• Metals: XAUUSD (Gold), XAGUSD (Silver)

• Crypto: BTCUSD, ETHUSD

• Forex: All major and minor pairs

Broker suffixes (e.g., XAUUSDz, US30.cash) are automatically handled.

Market Session Awareness

The EA checks if the market is open before executing any trade or position close, preventing errors during market closures.

Stop Level Protection

The EA automatically enforces broker minimum stop distances and freeze levels, preventing invalid stop loss and take profit placement.

Volume Normalization

Lot sizes are normalized to the exact decimal places required by each symbol's volume step, eliminating "Invalid volume" errors.

Order Validation

All trade requests pass through MQL5's OrderCheck function before submission, preventing terminal errors and log spam.

Strategy Notes

This EA is designed for traders who:

• Understand support and resistance concepts in both trending and ranging markets

• Want automated trading that adapts to price behavior (breakouts AND reversals)

• Accept the risks of trading near key structural levels

• Use appropriate position sizing for their account

The EA does not predict price direction. It identifies structural levels and executes trades based on how price reacts to those levels on H1 confirmation, managing risk through automatic position sizing, stop losses, and partial profit taking.
