VolatilityScanner EA MT4

Introduction to VolatilityScanner EA for MT4

VolatilityScanner EA for MT4 by Frank Paetsch is a breakout-focused, volatility-aware Expert Advisor that self-optimizes per symbol while it trades. Instead of constant re-optimization, it learns from recent performance and micro-tunes its own parameters within safe bounds. Attach it to one chart, let it scan multiple symbols, and trade the strongest conditions with institutional risk controls.

Options-grade logic. Forex speed. Self-optimizing.

Key Features

• Self-Optimizing Engine — Tracks per-symbol EMA of Profit Factor & Win Rate and nudges core settings (Donchian lookback, Min-ADX, ATR-based SL/TP, trailing multipliers) after X trades.
• Multi-Symbol Scanning — Reads MarketWatch or a CSV list, evaluates symbols on a timer, and focuses on viable breakouts using ADX strength with ATR/spread filters.
• Institutional Execution — ATR-based SL/TP, opposite-signal exit, optional time-based exit, ECN: modify after send, StopLevel/FreezeLevel guards, slippage control.
• Capital Protection — Daily loss cap, global equity stop, margin-aware lot sizing (auto-downshift to min lot or force fixed micro-lots), free-margin buffer and symbol block when min-lot is unaffordable.
• Attach-and-Go — One chart, timer-based scans, lightweight on-chart UI (color, corner/offset, font size).

Key Benefits

• Low Maintenance — No monthly re-optimization; the EA adapts while it runs.
• Market Fit — Donchian + ADX + ATR stack balances breakout capture with volatility-aware risk.
• Risk First — Daily caps, equity stop, fixed/auto lot options, and trailing exits help contain drawdowns.
• Scalable — Scan many symbols from one chart; CSV symbol control for curated lists.
• Prop-Rules Friendly — Daily loss/equity caps and hard SL/TP make it easier to align with challenge rules (your configuration required).

🔎 How the EA Adapts in Real Time

Self-Optimization Cycle

After each batch of trades per symbol, the EA reviews its EMA Profit Factor and Win Rate. If targets aren’t met, it micro-tunes within your bounds (lookback, Min-ADX, SLx, TP-R, trailing multiplier). Adjustments are deliberately small to avoid over-steering.

Breakout Framework

Donchian breakout defines entries; ADX filters trend strength; ATR sets SL/TP and trailing distances. Optional opposite-signal close or time-based exit can be enabled for regime changes.

Execution & Safeguards

Orders use ECN-safe send → modify. Spread/StopLevel checks, slippage limits, and max positions per EA/symbol keep exposure bounded. When free margin is too tight, symbols are blocked until safe again.

❓ Frequently Asked Questions

Do I need to re-optimize regularly?

No. The EA self-optimizes per symbol by measuring live performance and nudging parameters within your limits.

Which symbols and timeframe?

Attach to one chart on H1. It can scan all MarketWatch symbols or a curated CSV list.

Does it use martingale or grid?

No. It uses Donchian breakouts with ADX/ATR filtering and ATR-based SL/TP/trailing.

Is it prop-firm compatible?

It includes daily loss caps and a global equity stop. Configure limits to match your firm’s rules.

Do I need a VPS?

Yes. Continuous, timer-based scanning across many symbols requires 24/7 uptime and low latency.
