Range Filter Scanner MT4 is a scanner indicator for MetaTrader 4. One panel shows the latest range-filter signal on many symbols and timeframes, how many bars ago it came, and whether the next timeframe to the right agrees. It sends an alert when a new signal appears.
It places no orders. It runs the same range-filter engine as the free Range Filter Signals MT4 indicator, for a whole list of charts at once, on closed bars only.
Standalone: everything is built in. You do not need to buy or install any other product named on this page.
MetaTrader 4 edition: the same calculation, panel, inputs, alerts and buffers as the MetaTrader 5 version. The columns can use the nine MetaTrader 4 timeframes (M1, M5, M15, M30, H1, H4, D1, W1, MN1).
Quick start
- Attach it to any one chart. By default the panel lists the symbols in your Market Watch (Most symbols shown: 30) against M15, H1, H4 and D1.
- For your own symbols, set Which symbols to My list and fill My list, comma separated. Change Timeframes the same way.
- A cell reads "loading" until its history arrives. The panel title counts how many are loaded. Pop-up alerts are on. Switch on Play a sound, Push notification or E-mail if you want them.
What you see on the chart
- A panel with symbols as rows and timeframes as columns.
- In each cell: BUY or SELL and the closed bars since that signal, for example "BUY 3".
- "+" when the filter on the next timeframe to the right points the same way (the last column never has one).
- A brighter cell when the signal is recent (you set how many bars count as fresh).
- A tooltip with the filter's direction and range. Click a cell to open that chart.
How a signal is built
- The range is the average bar-to-bar close change, smoothed twice and multiplied. The filter only moves when price travels further than that range.
- A buy signal is a close above a rising filter right after a sell setup. A sell signal is the mirror.
- The forming bar is never used, so a cell does not change after its bar has closed.
Who it is for
For traders who use the range filter on several symbols or timeframes.

How often
Signals per month per symbol with the defaults (EURUSD, GBPUSD, USDJPY, XAUUSD, closed bars; a code count, not a trading result). M15 about 58 to 62, H1 about 15, H4 about 4 to 5, D1 under 1.
How it was checked
- The engine is the one in the free Range Filter Signals MT4. In the MetaTrader 4 Strategy Tester it matched an independent Python calculation on every bar. It also passed an every-tick repaint test (EURUSD H1, 2026, 8,417,316 ticks, 0 changed signals).
- The scanner: in the MetaTrader 4 Strategy Tester, 8,705,488 cell values matched the same Python calculation. They came from the engine, the loader and a run through the test period: 108 files, EURUSD, GBPJPY, XAUUSD and BTCUSD on M15, H1, H4 and D1, two settings. Cells used only closed bars, and after start-up the panel counts matched on all 8,674,390 checks.
Alerts and Expert Advisors
Alerts: pop-up, sound, push notification and e-mail, each switched separately. Cells that signal together are sent as one message. Nothing is sent while history loads, never twice for the same cell and bar, and not in the Strategy Tester.
Buffer 0 holds the number of fresh buy cells, buffer 1 the number of fresh sell cells, on the newest bar.
Questions
- Does it repaint? No. Cells use closed bars only.
- What does "+" mean? The filter on the next timeframe to the right is rising (for a buy) or falling (for a sell) too. It describes agreement, not a promise.
- Does it work on gold and crypto? Yes, on any symbol with history.
- How is it different from the free indicator? The same calculation as Range Filter Signals MT4: that one draws the filter on one chart. The scanner covers many symbols and timeframes with a higher-timeframe check.

Trading involves risk. The scanner shows a filtered trend. It does not predict the market, and past signals are no indication of future results.
