Harmonic patterns can be a goldmine if you’re serious about spotting high-probability reversals. But let’s face it—drawing and validating them manually? That’s a job for math wizards. Thankfully, the Basic Harmonic Pattern Indicator for MT4 does the heavy lifting and helps traders like us catch trend shifts before the rest of the market reacts.
As someone who trades structure and price action regularly, I find this tool a time-saver, especially when scanning for bat, gartley, butterfly, or crab patterns. It’s clean and accurate and gives you trade-ready signals with entry, stop loss, and take profit levels already marked.
Let me break it down for you.

What Is the Basic Harmonic Pattern Indicator?
This indicator automatically scans your MetaTrader 4 chart for harmonic patterns—those precise price structures based on Fibonacci ratios. It detects the most popular formations, including:
- Bat
- Crab
- Butterfly
- Gartley
Once a pattern is identified, it doesn’t just name it—it plots the entire pattern, gives you a Buy or Sell signal, and even shows Stop Loss and multiple Take Profit levels.
No guesswork. No drawing tools. No messy calculations.

How I Trade With This Harmonic Pattern Indicator
Let’s say you’re trading EURUSD or GBPJPY. Once the indicator finds a valid harmonic structure, you’ll see the full pattern painted on your chart with the name displayed.
For example:
- If it detects a Bullish Bat Pattern, it marks a Buy signal with:
- Suggested Entry Zone
- Stop Loss
- Multiple Take Profit levels (TP1, TP2, TP3)
From here, my approach is:
- Enter at the signal or after confirmation via candlestick (pin bar, engulfing, etc.)
- Set the stop-loss where the indicator suggests.
- Trail the SL as each Take Profit level is hit.
- Use your own risk-reward rule to manage exits. For me, 1:2 minimum.
One of my favorite features? The indicator works well on all timeframes, so the signals remain consistent whether I’m scalping a 15-minute setup or holding a swing trade on H4.
