In FX market analysis, the "harmonic patterns" are known for having high reversal advantage.

However, when you actually try to incorporate them into trading, you often encounter the following obstacles.

“It's difficult to open multiple currency pairs and measure Fibonacci ratios one by one.”
“I found it, but I’ve already missed the entry timing after the reversal.”
“Manual money management (lot calculation) and setting stop loss/take profit lead to order mistakes.”

To address these challenges, the MT4_Dashboard_Harmonics_v9 was developed.

More than a simple pattern-detection indicator,it provides a single-screen solution for up to 27 currency pairs scanning, visual preview orders, ATR-driven profit/stop settings, and naked-value settlement plus trailing stops—truly a “discretionary trading–oriented cockpit EA.”

1. Key features of『MT4_Dashboard_Harmonics_v9』

① Real-time monitoring of up to 27 currency pairs (Multi-symbol Scanner)

The dashboard lists the pairs under watch, and when a pattern is detected, the “pattern name” and trading direction (UP/DN) light up instantly. By simply clicking the symbol button, you can immediately switch to that chart.

② Automatic drawing of the four major harmonic patterns

Using ZigZag as the base, it detects the five points X, A, B, C, D and automatically calculates Fibonacci ratios.

Pattern Name	Characteristics and Reversal Target (D point)	Entry Target
Gartley	Most basic form. B retraces about 61.8% of XA, D retraces about 78.6% of XA	Look for balanced rebounds and declines
Bat	B retracement is shallow (38.2–50%), D reaches deeper (88.6% of XA)	Trade from deep pullbacks/retracements with high R:R
Butterfly	D extends beyond starting point X (XA 127.2% extension)	Target trend reversal points (tops/bottoms)
Crab	D extension is the sharpest (XA 161.8%), a powerful reversal pattern	Aim for extreme overextensions and rapid reversals

Bullish：Draws a green “M” shape
Bearish：Draws a red “W” shape

③ “Donchian Channel Filter” to reduce false signals

Even when the harmonic reversal zone (PRZ) is reached, there is always a risk the price breaks through. This tool includes a Donchian Channel Filter (DC Filter) that waits for the fact of breaking past recent high/low for a certain period and displays “Wait DC” to prevent unnecessary counter-trend entries.

④ “Trade Preview System” to prevent mistakes

Rather than a market order firing the moment you press BUY/SELL, three lines representing Entry (yellow), SL (red), and TP (green) plus the lot size are temporarily shown on the chart. You can visually verify risk-reward and then press CONFIRM to place the order, reducing hasty mis-orders.

⑤ Precise money management and settlement assistance

MM RISK (Money Management)：Automatically calculate lot size from permissible loss (percentage) of account balance and SL width
ATR-based SL/TP：Dynamically set take-profit and stop-loss widths according to market volatility
Auto Exit：Move to break-even, trailing stop, and batch close at daily/weekend

2. Practical trading procedure

This is the standard flow for using this tool.

Signal verification：Click the currency pair (UP/DN) detected in the left panel to display its chart.
Filter verification：When Donchian filter is enabled, confirm that the confirmed candle meets the condition (waiting shows “Wait DC”).
Order mode selection：Choose one of “MKT (market)”, “STOP (stop order)”, or “LIMIT (limit order)” from the bottom panel.
Preview launch：Click “BUY” or “SELL.” Entry, SL, and TP lines appear on the chart.
Order confirmation：Check risk-reward and lot size, then click “CONFIRM” (to cancel, click “CANCEL”).
Position management：After entry, depending on settings, break-even move and trailing stop automatically follow.

3. Traders for whom this tool is suited

Those who want to monitor multiple currency pairs and efficiently identify high-precision reversal points
Those who want to be liberated from manual Fibonacci ratio measurements
Those who want to maintain consistent money management (risk percentage calculation) without being swayed by emotions
Discretionary traders who want to reduce chart time and semi-automate exits
