News Sweep Sentinel MT4: Detecting Liquidity Sweeps and Reclaim Reversals

What News Sweep Sentinel Does

News Sweep Sentinel is a MetaTrader 4 indicator designed to detect a specific price pattern: the liquidity sweep followed by an immediate reversal. It watches prior swing highs and lows across a 20-bar lookback window, waits for price to push through one of those levels, and only signals when price closes back inside that level, proving the breakout failed.

The tool does not react to the initial break. A level being pierced means nothing on its own. What matters is whether price can hold beyond it. Only when a candle closes back through the swept level does the indicator mark the reversal.

Two signal types are produced:

• Regular sweep signals (BUY SWEEP / SELL SWEEP) when the pattern occurs at any time
• Premium signals (PREMIUM BUY / PREMIUM SELL) when the same structure appears inside a user-defined event window or its 60-minute tail

Each signal is labeled with the exact price level that was swept, not just a generic arrow. Once a level produces a signal, it will not fire again.

The Problem It Addresses

Stop-outs that reverse the moment you step away follow a predictable sequence: price pushes through an obvious level, triggers the resting orders behind it, then closes straight back inside the range. Traders who enter on the break get stopped. Traders who avoid the session entirely miss the reversal that follows.

Two mistakes dominate news trading. The first is trading the spike itself, where spreads widen and direction is least reliable. The second is dismissing the entire session as untradeable and missing the structured move that comes after the initial chaos.

News Sweep Sentinel isolates the second half of that sequence, the reclaim, while refusing to act during the spike. It requires proof that the breakout failed before it speaks.

How It Works in a Trading Session

The indicator tracks multiple conditions in real time and displays them on a lower panel so you can see a setup forming before it fires. The panel shows setup state as Idle, BUY ARMED, or SELL ARMED, along with gate status for ATR, spread, HTF filter, and cooldown.

A qualified sweep must meet every one of these criteria:

• Clearance - the candle must push past the swing level by at least 0.15 × ATR, not merely touch it
• Wick evidence - at least 35% of the sweep candle's range must be wick, showing rejection
• Reclaim - a subsequent candle must close back through the level within 15 bars, or the setup expires
• Invalidation logic - if 6 consecutive bars close beyond the swept level, the setup is canceled entirely
• Volatility gates - ATR(14) must be at least 0.85 × its 50-period baseline, and the confirmation candle range must stay under 3.0 × ATR to reject violent single-bar spikes
• Spread cap - the confirmation candle must close with spread at or below 30 points
• Optional HTF filter - an H1 EMA200 bias filter (off by default) restricts longs to above the average and shorts to below it

Because MetaTrader 4 has no built-in economic calendar to query, event windows are supplied manually. The tool ships with recurring daily proxy times at 08:30, 12:30, 14:00, 14:30, and 18:00 UTC, the slots where most macro releases land. You can edit this list to match the sessions you trade.

Swept levels are drawn as dashed lines with a SWEPT label and the exact price. Blue arrows below a bar mark buy sweeps; orange arrows above mark sell sweeps. Vertical dotted lines show active event windows. The lower pane plots working values, wick ratio, ATR, ATR baseline, and spread, on a shared 0-100 scale, plus status lanes for News Window, Cooldown, and Setup state.

Optional stop and target guides are available but disabled by default. When enabled, the stop sits 0.25 × ATR beyond the swept wick, with targets at 1.0R, 2.0R, and 3.0R. These are reference geometry only, sizing, entry timing, and execution remain the trader's responsibility.

Who This Indicator Fits

News Sweep Sentinel is built for traders who already understand that the first candle after a major release is usually a trap:

• Gold traders operating on M1 to M15 timeframes, where sweeps around scheduled releases are most pronounced
• Forex majors at M5 to M30 and indices at M1 to M15
• Liquidity and structure traders who want the sweep-and-reclaim sequence detected automatically rather than eyeballed on every chart
• Anyone who has been stopped out by a wick and then watched price return to the prior range without them

The tool is not suitable for traders looking for high-frequency signals in all market conditions. It is selective by design and will remain silent when volatility, spread, or reclaim conditions are not met.

What This Indicator Does Not Do

News Sweep Sentinel does not trade the spike. It waits for the reversal that follows.

It does not include a built-in economic calendar. Event windows are defined by you using the Recurring Daily HH:MM Proxy Times input. If you do not supply relevant times for your trading session, premium signals will not occur, but regular sweep signals will still function.

The stop and target guides, when enabled, are visual references only. The indicator does not execute trades, manage positions, or calculate lot size. It does not adjust stops dynamically or close trades at targets.

It is not designed for quiet, low-volatility markets. The ATR gate ensures it remains silent unless volatility is at least 0.85 × the 50-period baseline. If spread exceeds 30 points on the confirmation candle, the setup is blocked. That silence is intentional.

At least 6 bars must pass between signals in the same direction, and each swept level fires only once. If you are looking for continuous signal generation, this is not the tool.

How It Pairs with Other Tools in the Catalog

News Sweep Sentinel focuses on liquidity sweeps at swing levels. It pairs naturally with other MT4 indicators that handle different parts of market structure:

• Swing Trendline Break & Fakeout MT4 detects trendline violations and false breaks, complementing the swing-level focus of News Sweep Sentinel
• ICT SMC MT4 applies smart money concepts including order blocks and fair value gaps, adding institutional context to liquidity-based entries
• Big Figure Trap Signals MT4 identifies round-number traps, which often overlap with the psychological levels where sweeps occur
• Efficiency Step Reentry MT4 handles momentum reentry setups after a correction, useful for managing positions that began with a sweep signal

All MT4 indicators in the ZynAlgo catalog are standalone tools with no subscription or recurring cost. News Sweep Sentinel is priced at $0.58.

Installation: Copy the .ex4 file into the MQL4/Indicators folder inside your MetaTrader 4 terminal data folder, refresh the Navigator panel, then drag News Sweep Sentinel onto a chart. Swing lookback, sweep buffer, wick ratio, spread cap, and event windows are all editable in the Inputs tab.
