This page is the single reference for every input Axiom MA ships. It is organised by slot lifecycle rather than by the order TradingView happens to list the controls in: first what the slot does on and off, then where it reads from and when, then how it shapes itself, then how it presents, then how it contributes to the blend. Blended-group inputs and the one global control follow.

Before the catalogue, a banner that belongs at the very top of any MA reference on this tool.

Length: is not Trend Length:

Two inputs, two different jobs. They have similar names and sit next to each other in the inputs dialog. Confusing them is the single easiest misread on this tool, and it is the one most likely to change the colour of a line you are about to base a decision on.

• Length: is the MA's smoothing window. It drives the moving-average calculation itself. A larger Length: smooths more and lags more; a smaller Length: smooths less and tracks the price series more tightly. This input does not, on its own, decide whether the slot reports up or down — it decides what the slot's line actually is.

• Trend Length: is the rising-versus-falling comparison. It decides the slot's trend state by comparing the current MA value against the MA value from Trend Length: bars ago on the slot's own timeframe. Up when the current MA is greater than or equal to the past MA, down otherwise. The trend state drives the slot's line colour (up-state vs. half-opacity down-state) and the per-slot trend alerts. It does not change the MA itself at all.

One source-truth caveat: SWMA is fixed-length in the Lite library, so changing Length: does not change the smoothing window for that MA type. The length explanation below applies to the length-based types: SMA, EMA, RMA, WMA, and VWMA.

A worked example makes the split concrete. Imagine Slot 01 at SMA, Length: 20, Trend Length: 3, on a 5-minute timeframe.

• Change Length: from 20 to 50. The MA is now a 50-bar smoothing of price on 5-minute bars. The line on the chart moves to a different trajectory — generally slower, generally further from price. The trend state may or may not flip as a side effect of the new line having a different value now versus three bars ago.

• Instead, change Trend Length: from 3 to 20. The MA itself does not change — the 20-bar SMA is still the 20-bar SMA. What changes is the comparison window that decides the line's colour. The slot is now deciding up-versus-down by comparing the MA to its value twenty bars ago. The line's shape on the chart is identical; the colour rule is slower.

Two practical consequences to keep on hand:

• Shortening Trend Length: makes the slot flicker more often. Its line can flip colour from one bar to the next, and per-slot trend alerts become noisier. Lengthening Trend Length: asks the slot to move more before it is willing to call a change. None of that has anything to do with how much the MA itself smooths the price series.

• Changing Length: changes the MA itself. It will also indirectly change the trend state if the new MA crosses its own past value differently, but that is a downstream consequence, not the input's job.

Every per-slot entry below implicitly links back to this banner. Other pages in this pack refer you here rather than repeat it.

Per-slot inputs (three slots total: MA 01, MA 02, MA 03)

Each slot has the same set of inputs. The defaults below are the shipped Base defaults. Slots 01, 02, and 03 are configured identically except that their default timeframes are 5, 15, and 60 minutes respectively.

Enabling and hiding

The difference between Enable MA NN off, Hide MA NN Plot on, and Blended Weight = 0 is the single most productive distinction to hold in your head when configuring this tool. Visuals & Logic reinforces it on-chart; Workflows shows you the routine each state is actually good for; Alerts shows how each state interacts with the ten alert conditions.

Alignment qualifier: hidden slots still count only after their MA value is non-na. The source checks Enable MA NN and not na(slotNNValue) before adding a slot to the active alignment count.

Where and when the slot reads

Two notes worth keeping on hand:

• Each slot is its own higher-timeframe context. Slot 02 on 15 minutes is not reading Slot 01's 5-minute value and smoothing it further. It is evaluating its own SMA-of-close (or whatever you chose) on the 15-minute bars. The three slots are independent. They coincide only when you deliberately configure them to.

• The source is evaluated inside the slot's timeframe. Setting Source: to close on a 60-minute slot means "the 60-minute bar's close," not the chart bar's close. This matters for hl2, hlc3, and ohlc4 — they are computed from the slot's HTF bar, not from the chart's live tick stream.

How the slot shapes itself

Lite-library type note: Base exposes SMA, EMA, RMA, WMA, VWMA, and SWMA. SWMA is available, but it does not use the Length: value; the local Lite library routes it to Pine's fixed-length ta.swma().

How the slot presents

How the slot contributes to the blend

The blended-weight field sits at the centre of a lot of reader confusion, so three more clarifications you may as well read now:

• The weights are proportional, not absolute. The blend sums weight × value across contributing slots and divides by the sum of contributing weights. (20, 20, 60) and (1, 1, 3) produce the same blended value. The ratios matter; the totals do not.

• A slot with weight 0 is skipped entirely by the blend accumulator and contributes nothing to the trend vote. Its line stays on the chart (unless you hide the plot) and its per-slot alerts continue to fire on closed chart bars. "Weight zero" means "visible and vocal on its own, silent in the composite."

• There is no "normalise to 100" step and no enforcement that the weights sum to 100. The shipped 33.3 / 33.3 / 33.3 default sums to 99.9, which is fine — the divisor in the blend is whatever the enabled weights sum to.

A small reality check: if you find yourself tempted to set (33, 33, 34) to "make the total come out clean," the instinct is harmless and the math is going to produce the same blended line either way. The tool does not reward round numbers; it rewards proportions you can defend.

One sharper edge: the input does not enforce positive-only weights. Use zero-or-positive weights unless you are deliberately testing an edge case. If every enabled slot is weight 0, or unusual negative weights leave no usable positive total weight, the current source can leave the enabled blend at its default 0/down state. That is a configuration problem, not a market read.

Blended MA inputs

Collected in the MA Blended group. Three controls.

What the Base blended group does not include, on purpose:

• No Up Color: / Down Color: inputs. The blended colours are fixed in code — lime for an up-voted blend, red for a down-voted blend. There is no intermediate state and no configurable variant. If you need recolouring from the inputs dialog, that is a CTX feature. See the trim note below.

• No explicit "averaging rule" selector. The rule is weight-normalised averaging with a majority-vote trend resolution that breaks ties to uptrend. The rule is named and disclosed. It is not selectable. Visuals & Logic and For the Geeks both describe what the rule actually does on a real chart.

PU Settings — the one global control

This group holds the single most consequential input on the tool.

Because this input deserves real context, it has its own page. Read MTF & Repainting before you flip it in production. That page teaches what repainting is in this specific context, the global scope of the switch, the runtime-error guard that sits adjacent to it, and a verification walkthrough you can run on your own chart in under a minute.

Defaults as defaults

The shipped three-slot configuration — Slot 01 at 5 minutes, Slot 02 at 15 minutes, Slot 03 at 60 minutes, each with SMA, length 20, Trend Length 3, equal 33.3 weights, slot line widths 2, blended line width 3 — exists because it loads cleanly on a 1-minute chart of a regular-session liquid instrument and demonstrates what the tool does in plain terms.

That is what the defaults are. It is worth naming what they are not:

• The defaults are not a recommendation. SMA-20 on 5 / 15 / 60 is a legible first example, not a validated setup for any instrument, any session, any timeframe, or any trading style.

• The defaults are not optimised. Nothing was back-tested to produce them. They were chosen for the first ten minutes a new reader will spend with the tool.

• The defaults are not ranked. The three slots are equally weighted because "this is the tool's entry chart," not because equal weights are a neutral posture. Equal weights is itself a statement — one that says each of these three cadences gets an equal voice in the majority vote. Sometimes that is the read you want. Sometimes it is not. Workflows names the statement and the alternative explicitly.

If the tool is going to do real work for you, you will choose your own timeframes, lengths, trend-lengths, and weights. The shipped defaults are the chart you load before you make those choices, not a starting line someone else has already crossed on your behalf.

Version note — what Base deliberately does not ship

Across Axiom indicator families, the version progression is Base → CTX → STR when the full set exists. Base is the focused/free surface. CTX expands Base into a broader context tool. STR sits after CTX and spends extra processing on structure around the blended output, which is why STR carries fewer slots than CTX where both exist. Base holds back several features on purpose. Listing them here, in one place, saves you the search.

• Per-slot On Bar Close?. Base ships a single global switch. The CTX trim carries one per slot — ten of them.

• Cross-ticker input. Every Base slot reads the chart's own ticker. The CTX trim lets each slot read a different symbol.

• User-configurable colour inputs. Base slot colours (teal / blue / purple) and blend colours (lime / red) are fixed in code. The CTX trim exposes Up Color: and Down Color: inputs per slot and on the blend.

• The Pro MA palette. Base imports the Lite library's MA types; CTX imports the Pro library's wider palette (ALMA, KAMA, FRAMA, Jurik, Laguerre, VAMA, and the rest).

• Ten slots. Base ships three.

None of those absences is an oversight. Each is a version decision. The series exists so a reader can match the tool's surface to the surface their work actually needs. If three slots, one switch, the Lite palette, and fixed colours fit your work, Base is the right version and CTX would cost you attention for features you would not use. If your work genuinely needs one of the missing context features, Axiom MA CTX is the context-expansion version of this pack. If your work needs structure around the blended output, that is STR territory where an STR version exists.
