What the Alternate Bat Harmonic Pattern Indicator does on the chart
The Alternate Bat Harmonic Pattern indicator scans for the Bat pattern using a deeper fractal and a wider tolerance, so it catches the larger, swing-scale four-point structures that complete at the D point.
When a valid pattern completes it draws the zigzag and prints a green BUY arrow (D at a low) or a red SELL arrow (D at a high).

How to read signals from the Alternate Bat Harmonic Pattern Indicator
Also, the deeper fractal means fewer but larger patterns.

Entry idea (short). SELL arrow at the D high. Stop above D.
In practice, Exit idea. Target a retracement of the CD leg.
Tuning the Alternate Bat Harmonic Pattern Indicator inputs
Start with the defaults, then tune for your market. Depth (default 7) tunes how the calculation behaves; Tolerance (default 0.3) tunes how the calculation behaves. Also, every alert channel — pop-up, sound, email and mobile push — toggles independently in the same inputs panel, and alerts fire once per closed bar.
Recommended timeframes and instruments
This indicator needs room for structure to form, so favour the higher timeframes.
- H1 and H4 for reliable, tradable structures.
- Daily for the cleanest patterns and levels.
Below H1 you get frequent, lower-quality structures. Also, still, it works best on the majors and XAUUSD where swings are well defined.

FAQ
What does the Alternate Bat Harmonic Pattern measure?
It plots a clear signal layer that the Alternate Bat Harmonic Pattern computes from recent price and volume on the chart.
Is the indicator non-repaint?
By default the indicator only confirms a signal on the bar close, so the printed signal locks in once that bar closes. Then, typically, some users prefer the early intra-bar mode for faster signals — both options are in the inputs.
Which timeframe should I use?
There is no single best timeframe. Thus, yet, m15 to H1 is a common starting point for intraday traders, and H4 to D1 works for swing traders. Backtest the configuration on the timeframe you actually trade.
Does it work on instruments other than forex?
It works on any instrument MT4 and MT5 supports — forex majors, gold (XAUUSD), indices like US30 and NAS100, and major cryptos. Also, hence, truly, fast-moving instruments may need a smaller period setting.
Can I add alerts?
Yes. Next, plainly, Pop-up, sound, push, and email alerts live in the inputs panel. On MT4 and MT5 the alert plays on the bar close that triggers the signal. Also, this indicator ships with full alert functionality built in: popup alerts on the chart, push notifications to mobile MetaTrader, email alerts, and a sound alert with a configurable .wav file. In addition, you toggle each channel independently from the inputs panel (EnableAlerts, EnablePopup, EnablePushNotify, EnableEmail, EnableSound). Then, alerts trigger once per closed bar.
For external background reading, see the support and resistance basics. Are results guaranteed?
No. Trading involves risk. Results are not guaranteed. Past performance is not indicative of future results. Use the tool as one input. Always backtest before trading live.
