Introduction

Trading robots are no longer a novelty, yet finding one that truly focuses on simple supply and demand logic can still feel like a chore. The AF SUPPLY AND DEMAND EA brings that idea to life by mapping zones and executing trades with a clear set of rules. In this post we break down how the expert advisor works, how to set it up, and how to decide if it meets your own trading plan.

What Is the AF SUPPLY AND DEMAND EA?

The AF SUPPLY AND DEMAND EA is an automated trading program for MetaTrader 4 and MetaTrader 5. The robot scans the chart, draws supply (probable sell) and demand (probable buy) areas, then places orders when price reaches those levels. Unlike many EAs that use lagging indicators, this tool relies on fresh price structure.

Why Supply and Demand Zones Matter

Most price movements start from an imbalance between buyers and sellers. These imbalances create pockets—zones—where price often reacts again later. By plotting these zones, a trader gets a visual map of potential entries.

Key points:

• Supply zone: Last bullish candle before a clear bearish move.
• Demand zone: Last bearish candle before a clear bullish move.
• Zones act like magnets when price revisits.
• Combining multiple time frames adds extra context.

2. Open MetaTrader.
3. Go to File → Open Data Folder.
4. Navigate to MQL4/Experts or MQL5/Experts.
5. Copy the EA file into the folder.

Initial Settings Explained

Below is a rundown of popular parameters:

• LotType: Choose between Fixed, Dynamic, or RiskPercent.
• RiskPercent: If chosen, EA calculates lot size based on account balance.
• TimeFrameForZones: Pick M15, H1, H4, or Daily.
• DeleteOldZones: Removes zones after they’re retested.
• MaxOrders: Caps open positions for that symbol.
• SpreadFilter: Sets maximum spread allowed to place an order.
• NewsPauseMinutes: Minutes before and after a news event to halt trades.
• BreakevenPips: Distance in pips to set stop at entry.
• TrailingStopPips: Distance for trailing.

Keep settings in a notepad file so you can revert if needed.

Best Practices for Live Trading

1. Start on a demo account for two to four weeks.
2. Test one pair first, often EURUSD due to low spread.
3. Log every trade outcome in a spreadsheet.
4. Pair the EA with higher-time-frame trend direction—e.g., if daily trend is up, keep demand trades only.
5. Use a VPS. Downtime can break pending orders.

Risk Management Pointers

• Never risk more than 1–2% per trade on a live account.
• Keep total open risk below 5% at any moment.
• Avoid widening stop losses just to “give the trade room.”
• Scale down lot size during news weeks like NFP or central bank meetings.
• Withdraw profits regularly; it helps with discipline.

Back-Testing: Step-by-Step Tutorial

1. Under MetaTrader, press Ctrl+R to open the Strategy Tester.
2. Pick AF SUPPLY AND DEMAND EA from the list.
3. Select Symbol (e.g., GBPUSD) and Period (H1 is common).
4. Choose Every Tick modeling for accuracy.
5. Set the date range (at least two years is ideal).
6. Click Expert Properties to match live settings.
7. Press Start.
8. Once complete, examine:
   • Profit factor
   • Drawdown %
   • Average trade length
9. Save the report as both .html and .xml for record keeping.

Regular back-testing helps refine zone sizes or risk levels before going live.

Common Troubleshooting Tips

Sample Trade Walk-Through

1. EA marks a fresh demand zone on EURUSD H1 at 1.0930–1.0920.
2. Price revisits the zone five hours later.
3. EA sends a buy-limit order at 1.0930, 0.01 lots, stop loss 1.0910, take profit 1.0970.
4. Trade triggers, price stalls but soon climbs.
5. At +20 pips the EA moves stop to breakeven.
6. Trailing stop follows until final exit at 1.0962 for +32 pips.
7. Result: 2.9% gain on a $1,000 demo account when RiskPercent set to 1%.
