Nexus EURUSD Pro is a trend-continuation Expert Advisor for EURUSD on MetaTrader 4. Rather than trying to catch reversals, it waits for a trend to be established on the H1 chart, then enters on the first orderly pullback that holds above or below a dynamic support level. Trades are held for hours to a few days and are managed with a stepped trailing stop, so the system aims to capture the middle of a move rather than its exact start or end.

How the strategy works

The trend state is measured with a Donchian channel slope and an exponential moving-average stack on H1. When both agree, Nexus marks the trend as active and watches the M15 chart for a pullback that ends with a close back in the trend direction. A single position is opened with a stop loss placed beyond the pullback low or high plus an ATR buffer. The initial target is two and a half times the stop distance; once price reaches one times the stop distance, the trailing logic takes over and moves the stop in ATR-sized steps. Nexus takes at most one trade per trend leg and will not re-enter until a new pullback has formed.

Time and news filters

The EA does not open positions during the daily rollover window, when spreads on EURUSD widen briefly, and it can optionally block entries for a configurable period before and after high-impact scheduled events using the terminal's built-in calendar feed where the broker provides one. Existing positions are left to their stops during news; Nexus never closes trades at market simply because a release is due, as that would exit the strongest moves too early.

Position sizing and drawdown control

Lot size is calculated from a percentage of equity and the actual stop distance, so risk per trade stays constant even as volatility changes. A weekly loss limit pauses new entries for the remainder of the week when reached, and a maximum-open-loss input closes the position early if floating loss exceeds a hard percentage of balance, protecting against the rare gap through a stop.

Delivered files

You receive the compiled .ex4, two presets tuned for typical ECN spreads (Standard and Low-frequency), the strategy tester configuration for the sample backtest below, and a PDF explaining each input with screenshots of the chart panel. The chart panel shows the current trend state, the distance to the next entry level and the weekly loss headroom.

Realistic expectations

Trend following on a single pair produces long flat periods and clusters of small losses when EURUSD ranges, which it does for months at a time. The sample backtest on this page spans 2021 to 2025 and includes those periods deliberately. The figures are sample data from a tester and are not a projection. We recommend a demo run of at least eight weeks before allocating live capital.
