Harmonic Scanner Pro MT4 watches many symbols and timeframes at once for eight harmonic patterns: ABCD, Gartley, Bat, Alternate Bat, Butterfly, Crab, Deep Crab and Cypher. One panel shows where a pattern has just reached its potential reversal zone. It also shows where one is forming close to its zone, and how long ago the last one completed.
It uses only confirmed swings and closed bars. A completed pattern in a cell never changes afterwards.
MetaTrader 4 edition: the same calculation, panel, outcome table, 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 the indicator to any chart. The panel appears in the corner you choose.
- Choose the symbols (Market Watch or your list) and the timeframes. The default is M15,H1,H4,D1.
- Keep "near the zone" at 20% of XA and both alerts on, or change them.
- Click a cell to open that symbol and timeframe. Set the outcome table's stop to the one you would use.
Standalone: everything is built in. You do not need to buy or install any other product named on this page.
What it does
- Panel of symbols (Market Watch or your list) by timeframes (M15, H1, H4 and D1 by default, or any you choose).
- Completed: the pattern, its direction and the bars since it reached the zone. Fresh ones are highlighted.
- Forming: a pattern whose X, A, B and C are confirmed and whose price is within 20% of the XA leg of its zone (adjustable). The tooltip gives the zone prices. A forming pattern is not complete until a closed bar reaches the zone.
- Alerts when a forming pattern comes near its zone and when a pattern reaches it: pop-up, sound, push, e-mail. Alerts of the same second come as one message.
- Click a cell to open that symbol and timeframe, with your template if you set one.
- Outcome table: for each pattern, how often price moved 38.2% and 61.8% of the A-D leg back after the zone before a stop beyond the D level was hit. The stop is 2 zone half-widths by default (adjustable). It is counted in the bars loaded in every cell. A wider stop changes the numbers a lot, so set it to the stop you would use. This is past behaviour, shown as it is, not a forecast.
How patterns are found
- Swings: higher (lower) than the 10 bars before and not lower (higher) than the 5 bars after. A swing is known 5 bars later.
- Ratios: the commonly published Fibonacci ratios per pattern with a 5% tolerance (adjustable). For Cypher, C lies beyond A at 1.272-1.414 of XA, and D is at 0.786 of XC.
- Reversal zone: the D level plus and minus 3% of XA (AB for ABCD).
- Completion: the first closed bar that reaches the zone, provided no close went beyond it and price did not pass C.

How it was checked
- The swing and ratio engine is the one in the free Harmonic Signal Alerts 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 marks).
- The scanner: in the MetaTrader 4 Strategy Tester, 1,091,830 bar records matched the same Python calculation, with all eight patterns on. Each covers the completed patterns, the forming ones, the latest pattern per cell and the outcome counters. 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 8,674,389 checks.

Questions
- Does it repaint? Completed patterns do not. They are found on closed bars from confirmed swings and never removed. Forming patterns are, by nature, not final, and the panel labels them as forming.
- Why does a pattern show a few bars after point C? A swing is confirmed only after the bars on its right have closed.
- Does the outcome table mean the patterns work? It shows what happened in your history with one fixed rule. Results differ by symbol, timeframe and period. The past does not predict the future.

Trading involves risk. The scanner finds chart shapes; it does not tell you to buy or sell.
