Alerts

Axiom BB Pro provides 39 distinct alert conditions. Every alert fires only after the chart bar has closed and confirmed — none of them trigger mid-bar. This means you will never get an alert based on a provisional val...

Alerts

That said, an alert firing does not make a trade decision for you. These alerts notify you that a structural condition has changed. What you do with that information is still your job.

How alert timing works

All 39 alert conditions are gated by barstate.isconfirmed. In plain terms:

The alert evaluates its condition only after the current chart bar has fully closed.
If the condition is true on the confirmed bar, the alert fires.
If the condition was true mid-bar but false at the close, the alert does not fire.
If the condition was false mid-bar but true at the close, the alert fires.

This gating means you can trust that the condition was real when the alert triggered — it was not a provisional spike that reversed before the bar settled.

One important nuance: The alerts evaluate on the chart timeframe's bar close, not on the slot's higher-timeframe bar close. If you have a 60-minute slot running on a 1-minute chart, the condition is true on each confirmed 1-minute bar where it still holds. The slot's BB values may update only once per hour (if On Bar Close is on), but the alert check still happens on every confirmed chart bar, so repeated alerts are possible depending on your TradingView alert frequency.

Per-slot alerts

Each of the 10 slots has three alert conditions. That is 30 alerts across all slots.

Above Basis


Alert name	BB XX Is Above Basis
Fires when	The confirmed bar closes with price at or above that slot's basis line
What it confirms	That price was on the upper side of the structural center at that timeframe when the bar closed
What it does not confirm	That price will stay above basis on the next bar. That a trend is underway. That the positioning is meaningful without context from other timeframes.

Below Basis


Alert name	BB XX Is Below Basis
Fires when	The confirmed bar closes with price below that slot's basis line
What it confirms	That price was below the structural center at that timeframe when the bar closed
What it does not confirm	That a reversal or downtrend is underway. That you should exit a long position. A single bar below basis is a data point, not a verdict.

Basis Change


Alert name	BB XX Basis Change
Fires when	The above/below state flips from the prior bar — price crossed from above to below or from below to above the basis
What it confirms	That a regime transition occurred at that timeframe. The structural center was crossed.
What it does not confirm	The direction of the flip. The alert fires on any change in either direction. You need to check the chart or the companion above/below alerts to know which way the cross went.

A note on slot numbering: The alert name uses the slot's number (BB 01, BB 02, etc.), not the timeframe. If you reconfigure Slot 1 from 5-minute to 15-minute, the alert is still called "BB 01." Match the slot number to your configuration when setting up alerts.

Blended band alerts

Three alerts track the blended band's relationship with price.

Blended Above Basis


Alert name	Blended BB Is Above Basis
Fires when	The confirmed bar closes with price at or above the blended basis line
What it confirms	That price is positioned above the weighted-average structural center of all contributing slots
What it does not confirm	Structural bullishness in any meaningful sense. The blended basis is an average — price can be above the blend while being below the basis of the highest-weighted individual slot. Always check individual slot positions before treating a blended reading as significant.

Blended Below Basis


Alert name	Blended BB Is Below Basis
Fires when	The confirmed bar closes with price below the blended basis line
What it confirms	That price is positioned below the weighted-average structural center
What it does not confirm	Same caution as above, inverted. The blend can show bearish positioning while the highest-timeframe slot is still bullish.

Blended Basis Change


Alert name	Blended BB Basis Change
Fires when	The above/below state for the blended basis flips from the prior bar
What it confirms	That price crossed the blended structural center
What it does not confirm	Direction, or that any individual slot's basis was also crossed. The blended basis can shift with weight changes or slot activations, not just price movement.

Alignment alerts

Two alerts track whether all enabled slots agree on which side of their basis price sits. These are the closest thing the indicator has to a "consensus" reading — and they require the most careful interpretation.

All Above Basis


Alert name	All BB Slots Above Basis
Fires when	On a confirmed bar, every enabled slot with a valid basis has price at or above its basis
What it confirms	That all configured timeframes currently agree: price is above the structural center at every scale. This is a structural observation — all your configured layers are seeing the same positioning.
What it does not confirm	Trend direction. Trend strength. Whether the agreement is meaningful or coincidental. Whether it will last. Alignment tells you the timeframes agree, not that they are right. A mature reader treats alignment as a filter that narrows the possibility space, not as a verdict that confirms a trade.

All Below Basis


Alert name	All BB Slots Below Basis
Fires when	On a confirmed bar, every enabled slot with a valid basis has price below its basis
What it confirms	That all configured timeframes agree on bearish-side positioning
What it does not confirm	Same cautions as All Above. Agreement on the bearish side does not confirm a downtrend — it confirms agreement, which is a different thing.

Alignment alert dependency: These alerts check every enabled slot that has a valid (non-na) basis. If a slot is enabled but its cross-ticker source has no data, that slot may produce na for its basis and could be excluded from the alignment check. Make sure your enabled slots are producing valid data before relying on alignment alerts.

Blended cross alerts

Four alerts track specific price crossings of the blended band levels. These are the most likely to be misused as trade entry signals, so the framing here is especially important.

Crossed Above Upper Band


Alert name	Blended BB Crossed Above Upper Band
Fires when	Price crosses above the blended upper band on a confirmed bar
What it confirms	That price exceeded the weighted-average upper boundary. This is a snapshot of a cross, not a forecast.
What it does not confirm	That a breakout has occurred. The blended upper band is a synthetic level — it is the average of several upper bands. Breaking above it means price exceeded a weighted average, which is less meaningful than breaking above a specific single-timeframe upper band that you understand.

Crossed Below Lower Band


Alert name	Blended BB Crossed Below Lower Band
Fires when	Price crosses below the blended lower band on a confirmed bar
What it confirms	That price dropped below the weighted-average lower boundary
What it does not confirm	That a breakdown has occurred. Same reasoning as above — the blended lower band is a synthetic level.

Crossed Above Basis


Alert name	Blended BB Crossed Above Basis
Fires when	Price crosses above the blended basis on a confirmed bar
What it confirms	That price moved from below to above the blended structural center
What it does not confirm	A regime shift. The blended basis is a weighted average of several moving averages. A cross of this level is softer than a cross of a single well-understood basis at a specific timeframe.

Crossed Below Basis


Alert name	Blended BB Crossed Below Basis
Fires when	Price crosses below the blended basis on a confirmed bar
What it confirms	That price moved from above to below the blended structural center
What it does not confirm	Same caveats.

Hidden data plots

The indicator provides two hidden plots that do not draw on the chart but are available as data sources in TradingView's alert creation dialog:

Active Above Basis Count — the number of enabled slots currently showing price above their basis
Active Below Basis Count — the number of enabled slots currently showing price below their basis

These can be used in external alert configurations. For example, you could set up a TradingView alert that fires when "Active Above Basis Count" crosses above 2 (meaning at least 3 slots agree on bullish-side positioning, without requiring full alignment).

Alert misuse patterns

These are the most common ways alerts from this indicator get misinterpreted. Recognizing them before they happen is cheaper than learning from a bad trade.

Treating alignment alerts as buy/sell signals

"All slots above basis" is a structural observation, not an entry signal. It tells you the configured timeframes agree on positioning. It does not tell you that a trade is safe, profitable, or well-timed.

The way this goes wrong in practice: you set up the alignment alert. It fires. All timeframes agree, and it feels like confirmation. You enter a position because "the structure supports it." And then the lowest-timeframe slot crosses its basis the other way, alignment breaks, and you are left holding a position whose structural support just disappeared — because the alignment that felt durable was actually the peak of agreement right before one timeframe turned.

This does not mean alignment alerts are useless. They are good at flagging moments of structural agreement that deserve your attention. But "deserves attention" and "enter a trade" are different actions. Use alignment as a filter within a broader process, not as the process itself. When the alert fires, check how the alignment formed, how deep it is, and what other factors support or contradict it before you act.

Treating blended-cross alerts as breakout signals

The blended band is a weighted average. Crossing it is not the same as crossing a BB at a specific, meaningful timeframe. If price crosses above the blended upper band but is still inside the 60-minute upper band, the "breakout" is an artifact of averaging — the blend's upper band was lower than the 60-minute upper because averaging pulled it down.

The danger is that the alert sounds definitive. "Crossed Above Upper Band" feels like a breakout notification. But the upper band in question is a synthetic level, and the cross means price exceeded a weighted average of several upper bands — some of which may have been exceeded hours ago, while others have not been touched. Check which individual slots price has actually crossed before treating the alert as structurally meaningful.

Relying on basis-change alerts without checking direction

The "Basis Change" alert fires on any flip — from above to below or from below to above. It does not encode direction. If you set up a basis-change alert and act without checking the chart, you do not know whether the cross was bullish or bearish. This sounds obvious, but under time pressure it is easy to assume the direction based on recent context rather than checking.

Pair basis-change alerts with the corresponding above/below alerts, or check the chart when the alert fires. The basis-change alert tells you something happened. The above/below alerts tell you what.

Expecting alerts to fire on the HTF bar close

Alerts evaluate on the chart timeframe's confirmed bar, not on the slot's higher-timeframe bar close. If you are on a 1-minute chart with a 60-minute slot, the "above basis" condition is true on every confirmed 1-minute bar where it still holds — not just at the top of the hour. This means repeated alerts are possible for the same structural condition, depending on the TradingView alert frequency you choose.

If you want to be notified once when a condition changes rather than on every bar where it holds, use the "Basis Change" alert (which fires on the transition) rather than the "Above Basis" or "Below Basis" alerts (which fire on the state). You can also configure TradingView's alert frequency settings ("Once Per Bar Close" vs. "Once Per Bar") to control repetition, but those settings apply to the chart bar frequency, not to the HTF candle.
