How to read signals from the On Balance Volume Indicator

The On Balance Volume Indicator highlights shifts in transactional activity that confirm or contradict the price move. Also, still, hence, a typical workflow looks like this.
Entry idea (long). Wait for a momentum bar with above-average volume to break a recent minor high. Next, wait for the bar to close. Intra-bar values can shift.
Entry idea (short). Wait for a momentum bar with above-average volume to break a recent minor low. The same close rule applies.
Exit idea. Some traders take partial profit at one R and trail the rest with structure. Some traders trail with structure. Others trail with the indicator itself.
These are concepts, not rules. Then, backtest on your instrument and timeframe before live capital.
Tuning the On Balance Volume Indicator inputs
Start with the defaults, then tune for your market. UseTickVolume (default true) toggles this behaviour on or off. Thus, yet, 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
On Balance Volume Indicator relies on volume, which is most meaningful on higher timeframes.
- H1 and above where bar volume carries weight.
- H4 to Daily for confirming larger moves.
Sub-H1 tick volume is noisier, so pair it with price structure on EURUSD, GBPUSD and indices.

FAQ
What does the On Balance Volume measure?
It highlights sums volume up and down to confirm price moves on the chart.
Is the On Balance Volume Indicator non-repaint?
By default the indicator only confirms a signal on the bar close, so the signal stays fixed once that bar closes. Then, 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, still, 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. Thus, fast-moving instruments may need a smaller period setting.
Can I add alerts?
Yes. Also, still, hence, truly, hence, you toggle pop-up, sound, push, and email alerts in the inputs. On MT4 and MT5 the alert plays on the bar close that triggers the signal. Next, the On Balance Volume 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. You toggle each channel independently from the inputs panel (EnableAlerts, EnablePopup, EnablePushNotify, EnableEmail, EnableSound). Then, alerts trigger once per closed bar.
