Relative charting, Gann angles, and trendline breakouts

Chart geometry is not self-proving. The same monthly S&P 500 history can produce different angles, different time counts, and different channel edges once the vertical scale changes.

Editorial: TradersWeek treats scale as an explicit hypothesis. A 1x1 angle is only meaningful after you choose whether geometry is anchored to a fixed price-per-bar unit or to a named trend vector. The same structure should confirm or fail on both alignments before a channel breakout is called.

Autosize is not a scale hypothesis

A charting program's autosize fit of a monthly S&P 500 history produced 10.86 points per month and an uptrend-vector reading of 51.10 degrees. That autosize-ratio is treated as geometrically meaningless because it depends only on how much history happens to be on screen.

The gann-1x1 needs a chosen price unit

Traditional Gann alignment uses a predetermined price-per-period unit so that one price unit equals one time unit at 45 degrees. That line is the gann-1x1. On the monthly S&P 500 example the chosen unit is 10 points per month rather than 1 point per month because the latter is impractical at that price level.

After aligning the same monthly S&P 500 chart to 10 points per month, the 10/M line is the 45-degree gann-1x1 and the uptrend-vector reads 53.45 degrees. That gann-1x1 is described as cutting the 90-degree price-time square in half and as marking support and resistance at two labeled points.

A degree reading can be reread as a time count

On the 10/M Gann alignment, a double-candle reversal is located at months 53 and 54 after the uptrend high, in March and April 2012, matching the 53.45-degree vector reading. Counting 51.10 months from the same high using the autosize angle does not mark a top or bottom.

Time-angle-echo is the idea that the degree reading of a trend vector on a properly scaled Gann chart can be reread as a count of bars or months from a pivot, producing a dated window where a reversal is hypothesized. The aligned 53.45-degree reading supplied that window. The autosize 51.10-degree reading did not.

Relative-charting makes the named trend the 1x1

Relative-charting inverts the Gann convention. It first converts a named uptrend into a price-versus-time ratio and then changes the vertical scale so that same vector becomes the 1x1. In the example, the October 2002 to October 2007 rise from 768.63 to 1,576.09 is set to exactly 45 degrees, and all later geometry is measured from it.

An uptrend-vector is a straight line from a defined swing low to a defined swing high. Under Gann alignment it is compared with a fixed gann-1x1. Under relative-charting it becomes the 1x1, and later angles, channels, and shapes are measured against that trend rather than against a fixed price-per-period unit.

The same wedge does not reprint on both scales

On the monthly S&P 500 relative chart, a circle construction is used both to link six historical points retrospectively and to enclose the later large uptrend as a rising wedge whose four interior points are being tested.

That enclosure is the rising-wedge-test. A close through the enclosure is a candidate breakout. A reversal that merely shifts higher along the same lines is not.

The same rising-wedge outline on a Gann-scaled chart does not reproduce the exact highs and lows of the relative chart. Price is described as reacting with an upward shift, so a later monthly close is required to distinguish a genuine breakout from another upshifted reversal along the enclosing lines.

A parallel of the uptrend-vector, when anchored at the circle bottom on the relative chart and then moved to a new source near 567, is presented as valid support for two lesser lows.

Combinational-analysis requires a compatible reaction

Combinational-analysis treats the two geometries as complementary rather than mutually exclusive. A bullish upshift and a possible push toward the prior all-time high on the Gann chart is used as supporting context for a wedge breakout hypothesis on the relative chart, and the reverse reading is used the other way.

Editorial: TradersWeek does not treat either alignment as a completed signal on its own. An upshift or breakout on one alignment is only treated as actionable if the other alignment shows a compatible reaction.
