Smi Ergodic Scanner MT4

One board, twenty eight symbols, and a momentum reading calm enough to trust. SMI Ergodic Scanner runs Blau's double smoothed index across four timeframes per symbol, grades a crossing by whether it happened beyond the levels, and keeps the oscillator under the board so the crossing can be checked by eye.

SMI Ergodic Scanner is two products in one file. The first is the SMI Ergodic index itself, in this chart's own sub window: the index, its signal line, and the histogram between them.

The second is a board that runs the same calculation across a list of symbols on several timeframes at once. The board says which instruments have signalled and how recently; the chart under it shows you what produced the signal, so you do not have to attach a second indicator to act on what the table found.

The board

A row per symbol, a column per scanned timeframe, up to four columns and up to twenty eight symbols. It ships scanning fifteen symbols and is raised to twenty eight from one setting. The symbol list is comma separated, or the board can take the Market Watch list instead. Broker prefix and suffix are detected from the chart you are on, or given by hand. Out of the box the board scans four timeframes: M15, H1, H4 and D1.

A cell reads like ^14b G2: which side the signal was on, how many bars ago it fired, and its grade. The word flat means the calculation ran and found no direction. Three dots mean the cell has not been measured yet, and hovering it explains why in words once tooltips are switched on, which they are not by default. A signal older than the freshness threshold keeps its colour but is drawn quieter, so hue says direction and weight says how much it still matters. A row carrying a fresh signal anywhere in it gets a wash of the accent colour.

The AGREE column is the reason to use a board rather than eight charts. For each symbol it takes the visible timeframe columns, finds the majority side, and prints something like v3/4: the direction, and how many of the visible timeframes stand on it. When every visible timeframe agrees, the cell is drawn bold in that side's colour. A tie prints a dash and is deliberately not a verdict. With a single timeframe visible the column is removed entirely rather than printing 1/1, which would only restate the cell beside it.

Column headers are buttons. Click a timeframe header to sort by that column, freshest first, rows with nothing in it at the bottom; click it again to reverse. Click AGREE to sort by agreement, full agreement first. The active header carries the accent colour and a caret, so the sort state lives on the control itself. A separate Sort button cycles freshest, grade and name for a whole-board order.

A Show button cycles all, buys, sells and fresh. Buys and sells follow the AGREE verdict and not any single cell, so a row shown under buys always reads an up glyph in AGREE, and a tie appears under neither. This filters the view and not the calculation: a hidden row is still measured and can still alert.

The legend above the table decodes the notation in one line, including the grade half, which it prints only because this port grades. It can be switched off. Timeframe buttons show and hide a column without stopping the calculation behind it.

The visible row count is fitted to the chart pane and the row setting is a maximum. No page buttons are drawn when everything fits; when it does not, previous and next appear with the page number. Because the board never draws more rows than the pane holds, the page buttons are always on screen and always reachable, however tall the row setting is.

Two status lines are always on show: symbols ready of total, how long since the last update, signals in the lookback window; then either the watchdog line or a sentence explaining why nothing is showing.

Diagnostics

A second panel, off by default, answers the question "why is there no signal": symbol coverage, which series are short of bars, how many signals were found in the window, and how many symbols this indicator switched on in Market Watch to do its work. A cell that could not be measured is explained rather than left blank.

The chart indicator

In its own sub window: the index and its signal line, and the difference between them as a histogram, coloured by whether the momentum is expanding or fading rather than merely by its sign. Divergence lines are drawn on the index and, if you want them, between the matching pivots on the price chart as well.

The settings sheet

Values covers the timeframe, the long smoothing of twenty, the short smoothing of five, the signal length of five, the two grading levels at plus and minus twenty, and the three divergence rows. Styles covers the palette, the index and its signal, the line width, and the histogram, which can be reduced to one plain colour. Every Values row has steppers, a range and a sentence of help.

Alerts covers the master switch, the per-event switches, the four channels, the cooldown and a test button.

Three colour schemes, including a colour-blind safe one that uses blue and orange rather than red and green. Panel position, scheme, the sort, the filter, which columns are visible and every value changed on the sheet persist per chart across a timeframe change and a terminal restart. The interface is English.

Alerts

Off out of the box. A master switch sits on the panel itself, next to a Test alert button that fires through every channel currently on.

The events are a fresh BUY and a fresh SELL, declared separately for each scanned timeframe, plus data health, which speaks when a symbol loses or regains its data. There is a minimum grade setting, and because this port grades its cells the setting does real work here.

The channels are a popup window, a sound, a push to the mobile terminal and e-mail. The cooldown is kept per cell and per event, thirty minutes by default. Telegram is not part of this product.

Cost

The work is budgeted: a set number of symbols is refreshed per timer tick, so a long list spreads its load instead of stalling the terminal. The first pass is progressive and the panel reports the percentage measured.

Reading it from an EA

The chart indicator publishes eight buffers, all readable through iCustom and CopyBuffer. Buffer 0 is the index and buffer 1 is its signal line. Buffer 2 is the difference between the index and its signal, drawn as a histogram, and buffer 3 is the colour index that paints it. Buffer 4, Signal, is +1 on a BUY bar, -1 on a SELL bar and 0 otherwise. Buffer 5 is the grade of that signal, buffer 6 carries the divergence marks, and buffer 7 is the zero line.

This product has no separate Buy and Sell price buffers, because there is no price to put an arrow at in a sub window. The signal is buffer 4 and it is the contract: filled on every pass whatever the Styles tab says, and present in the Data Window. Hiding a plot is done by taking its colour away and never by emptying a buffer, so every index above stays readable with the display switches off.

This map is the scanner's own. The free single chart indicator publishes the same eight indices and adds an Override buffer at index 8, which the scanner has no use for. Read the list above rather than assuming the two are interchangeable.

The board itself is a panel and not a buffer. It is read by eye and by alert.

The single chart indicator behind this one, SMI Ergodic MTF, is free and carries the same engine. If you follow one symbol, take that one; this scanner exists for watching many at once.

Provenance

This is a port of the SMI Ergodic Indicator, William Blau's index, which is his TSI under another name. The mathematics is public and the indicator is built into TradingView, which makes a port by formula admissible. Two deviations are declared. The scale is multiplied by one hundred so the pane reads in per cent as everywhere in this line, which moves no crossing, no zero and no divergence by a single bar and changes only the axis label and the number in a scanner cell. And the recursion starts from zero on the first bar, where Pine seeds each average with a mean and returns nothing before that.

The product is called SMI Ergodic Scanner because that is the name of the method, not because authorship of the method is claimed here. The original work belongs to its author.

Honest limits

The board reads closed bars and counts a cell's age in closed bars. The chart indicator under it can show a signal on the bar still forming, and such a signal can be gone by the close. What has been published on a closed bar does not change afterwards.

The oscillator is live on the forming bar. A cross that exists mid-bar can be absent at the close, and the panel line and the grade go with it. Closed bars do not change.

Double smoothing is late by construction. The index is quiet in a chop because it is meant to be, and that same quietness means it arrives after a fast move has already started.

The levels grade a signal, they do not filter one. Every crossing is published, and a crossing far from the levels is graded one rather than suppressed.

The long and short lengths move every crossing the product will ever show. Two configurations give two different sets of signals and neither of them is the true one.

AGREE counts timeframes, it does not estimate probability. Four timeframes agreeing means four correlated readings of one instrument agreed. A tie produces no verdict on purpose and is hidden by both the buys filter and the sells filter.

Scanning costs. Twenty-eight symbols on four timeframes is a hundred and twelve cells and will be felt on a slow machine; the budget setting is what you turn down.

Symbols your broker does not carry, and series with fewer bars than the settings need, cannot be measured, and the board says which and why rather than leaving the cell blank.

No profit figure, win rate or backtest result is claimed here.
