HighLow Trail EA - Trail smarter with Market highs and lows.

Category: Trending and Range Market

Last updated: 2025-09-17

Terminal: MT4

Preferred pairs: All

Timeframe: Any

HighLow Trail EA is an MT4 Expert Advisor that manages stop-losses for your open orders.
It watches recent candles and shifts the SL to the latest meaningful swing High/Low, so your exit level follows price as the market moves in your favor.

Why this matters

• Recent Highs/Lows often act as support/resistance.

• Trailing to these levels creates logical, price-based exits instead of fixed distances.

Why Is It Useful?

Good trading = good risk management. This EA helps you:

• Always have a stop-loss (adds one if missing).

• Trail automatically when price moves your way.

• Limit losses and secure profits without constant screen time.

• Avoid margin calls by keeping risk controlled.

• Stay objective — no emotional decision-making.

• Get notifications each time the SL updates (alerts, push, or email if enabled).

Key Features (At a Glance)

• Price-action trailing using recent Highs/Lows (not a fixed pip step).

• Filters to choose exactly which orders to manage (type, Magic Number, Comment).

• One-click on/off control via a graphical panel (optional).

How It Works (Simple)

• BUY trades: SL trails below the lowest low found within Bars To Scan.

• SELL trades: SL trails above the highest high found within Bars To Scan.

• When price makes a new swing and your trade is in profit, the EA moves SL to that new level.

• If price reverses and hits SL, you exit safely with reduced give-back.
