TopDown Price Action

TopDown Price Action EA is a fully automated multi-timeframe Expert Advisor for MetaTrader 5, built around the same top-down analytical framework used by professional price action traders. Rather than relying on lagging indicators or arbitrary signals, the EA reads raw market structure across two timeframes simultaneously — establishing a high-timeframe directional bias on H1 or M30, then dropping to M15 or M5 to execute with precision. Every trade begins with a question: where is the market trying to go, and is the path clear to get there?

The bias engine recognises three distinct structural patterns — the Continuation Pattern, a three-candle sequence where momentum compresses then expands in the same direction; the Engulfing, where a single candle absorbs the entire body and directional wick of its predecessor; and the Break of Structure, where price decisively closes through the most recent swing level with a clean, committed body. Each pattern is validated against strict geometric rules that mirror how a discretionary trader would assess the setup, with configurable thresholds that allow you to tighten or loosen the criteria during optimisation.

Before any trade is considered, the EA applies a clean traffic filter — the single most important concept separating profitable setups from traps. It scans the path between the setup and the target for opposing candle closes and historical support and resistance zones, including flipped levels. If the road is blocked, the trade is skipped entirely, regardless of how strong the bias looks. This filter alone eliminates a large class of setups that would otherwise result in price stalling or reversing mid-move.

Confirmation is handled entirely on the lower timeframe, using only Continuation Patterns and Break of Structure signals — never engulfing alone. The EA supports two confirmation scenarios: price breaking the reference line directly with a confirming pattern, or price breaking the line clean and forming the confirmation within the following two candles. The confirmation candle's body is validated for size to ensure the resulting stop loss remains proportionate to the move.

Risk is fixed at one percent of account balance per trade, with a dynamic lot sizing engine that adjusts progressively after each result — stepping up after wins and stepping down after losses, always capped at a configurable maximum risk ceiling. The EA supports all four major dollar pairs — GBPUSD, EURUSD, NZDUSD, and AUDUSD — and enforces a single-trade-per-symbol rule, giving a maximum of four simultaneous positions across the portfolio. Every parameter, from pattern detection ratios to stop loss buffer and risk reward, is exposed as an input for full customisation without touching the source code.
