Axiom MACD Osc STR

A bounded, ATR-normalized, sigmoid-mapped read of the MACD, signal, and histogram triple across up to five curated slots, blended by weight, with four interpretive structure layers drawn on the blend itself. STR is the structure-expansion trim of the MACD Osc family.

The pane lives below price. It does not take trades, does not promise turns, and does not replace price action. It gives a serious reader a comparable read across timeframes and symbols, and it gives that reader four specific ways to interrogate the blend once it is drawn.

Where this version sits

Axiom indicator families use a Base -> CTX -> STR progression when the full set exists. Base is the free, focused version: three context slots, chart-symbol only, limited filtering through the MA surface, and one global bar-close posture. CTX expands that same MACD Osc logic into broader context: up to ten slots, per-slot symbol and timing control, and the larger Extended MA surface. STR is the structure expansion at the end of the series. It keeps CTX-style per-slot control and the Extended MA surface, but it runs five slots instead of ten because the extra processing budget goes into structure on the blended MACD output itself.

That trade is the point of this trim. You give up CTX's ten-slot breadth and gain four structure reads around the blended MACD line: divergence against chart price, Keltner stretch, BBWP width regime, and Donchian range. STR sits at the end of the sequence; it is the structure version, not a reduced context version. It is the more advanced structure variant for readers who want to ask what the blended MACD is doing relative to its own recent behavior without leaving the pane.

Why this trim exists

If you have ever stacked a classical MACD on a 5m, a 15m, and a 60m chart side by side and tried to eyeball whether the 60m reading is "bigger" than the 5m reading, you have already met the problem this trim is built around. The raw MACD gap on an S&P e-mini and the raw MACD gap on a twenty-dollar single name do not share units. Neither do the 5m and the 60m readings on the same symbol. Raw magnitudes stacked together look comparable and are not. Visual similarity in that situation is a lie dressed as evidence.

Axiom's ATR-sigmoid normalization is the fix, and the fix has a cost. It maps each slot's MACD, signal, and histogram values into a bounded 0..100 pane where 50 is the zero point of the transformed series. For the histogram, that means MACD equals signal. For the MACD line itself, it means the fast-minus-slow gap is near zero. You lose the raw magnitude read. You gain comparability across slots, symbols, and MA families. Most traders who actually run more than one timeframe decide that tradeoff is worth making once they sit with both.

Base stops there — three slots, a blend, a histogram, a clean pane. That is the whole trim, and it is enough for many readers. STR exists because some readers want to keep the normalized pane and ask four more specific questions of the blended line:

• Is the blend stretched against its own recent range? (Keltner envelope on the blend.)

• Is the blend printing fresh highs or lows in its own lookback? (Donchian channel on the blend.)

• Is the blend in an expanded or compressed width regime by its own history? (BBWP on the blend.)

• Has the blend formed a confirmed divergence against a confirmed price pivot pair? (Divergence triangles on the blend.)

All four read from the same line. That fact is load-bearing and every page in this pack that mentions them repeats it. They are four framings of one line — not four independent witnesses, not four confirming voices, not a voting system. Read them that way and they earn their place. Read them as independent confirmations and the pane will flatter you into a mistake.

Against Base, STR changes daily use in two visible ways: five slots instead of three, and per-slot On Bar Close? instead of one global repaint switch. Against CTX, the tradeoff is different: STR keeps the per-slot control posture but caps the stack at five slots so the blended-line structure layer can run. The pack treats those surfaces as tradeoffs the reader now owns, not as upgrades the reader has earned.

Who it is for

A discretionary or semi-systematic trader who already trusts the MACD frame, already runs a small stack of timeframes, and wants a fourth or fifth voice — a higher timeframe, a cross-ticker benchmark, a different MA family — without managing ten slots. Someone who will read a divergence triangle as a question to ask of the slot stack rather than as an entry. Someone who is prepared to tune a handful of Pro MA families (ALMA, KAMA/FRAMA, Jurik, Laguerre, VAMA) when evidence pushes them to, and to leave the defaults alone when it does not. Someone whose process already has entry and exit reasoning and wants a context pane, not a green-light machine.

Who it is not for

• A reader looking for buy and sell flags. The pane reports state and geometry. It does not take a position on what to do about either.

• A reader who would enable five slots at identical EMA 12/26/9 across five timeframes and read the resulting blend as five-way consensus. That configuration is the alignment trap with extra slots attached. Base will serve you better and the trap will hurt you less there.

• A reader who wants ten-slot context breadth more than blended-line structure. That is the CTX job: more slots for the same core MACD logic, with per-slot controls and Power User surface. STR spends five of those ten possible slots on structure around the blend instead.

• A reader who will set Pivot Len to three to "see more divergences" and trade every triangle. That is not a configuration error this pack can catch for you — it is a reading error this pack cannot prevent.

If any of those sound like your intent, stop here. The trim you want is probably elsewhere, and the pack would rather say so out loud than flatter you into a mismatch.

The single most magnetic misread

A confirmed bullish divergence triangle is not an entry. It is a specific geometric fact: two confirmed price pivot lows in lower-low order, paired with two blended-MACD values at the same historical offsets in higher-low order. That is a description of a moment. It does not predict the next bar, it does not survive into that bar by default, and it does not obligate price to do anything in particular about the pattern it just finished forming.

This matters because the triangle is the most visually magnetic element on the pane, and it prints on exactly the kind of moment when a reader is already tempted to fade price. If you treat the triangle as a call, the tool will look like it lied to you. The tool did not lie. You imputed a claim the tool never made.

Every page on this pack carries the qualifier alongside every mention of divergence. That is not caution theater. It is the single failure mode that costs readers of this tool the most.

Estimate boundary, stated plainly

The pane is a bounded, normalized read of a classical construction. It is not a new oscillator, it is not a black box, and its behavior is auditable from the pane itself.

• Fifty is neutral. On the MACD line, fifty means the fast-minus-slow gap is near zero. On the histogram, fifty means MACD equals signal. It is not a magnet, not a target, not a mean-reversion destination.

• Zero and one hundred are asymptotes, not reversal zones. They are what happens when the sigmoid's tails flatten under the current ATR Sensitivity and volatility regime. Pinning at a boundary is not intensity; it is saturation.

• The blend averages, it does not resolve. A weighted mean over slots that disagree is not consensus. It is an arithmetic summary of disagreement.

• Per-slot On Bar Close? is a tradeoff, not a solution. ON gives you the previous slot-bar read, which is steadier on confirmed history. OFF gives you a live read that can repaint until the slot bar closes. Each slot is a decision you own, and a blend whose slots are mixed across the two postures carries the weaker posture of its members.

• The four structure features are not independent. Divergence, Keltner, BBWP, and Donchian are four framings of the same blended fast line. When they agree, one line is agreeing with itself. Their agreement is mechanical. Their disagreement is informative.

If any of those five facts surprises you after you have used STR for a week, come back and read this page before you touch the pane again.
