Rebuild MACD-Mo and MACD-H before treating them as signals

A named variant is not yet a built series

MACD is a price-based oscillator formed from the difference of two smoothed averages of the same market series. A later treatment of MACD Momentum named two further series, MACD-Mo and MACD-H, without showing how those series are built.

MACD-Mo is a momentum-style transform of MACD that a reader asked to have constructed explicitly after finding it named without a formula. MACD-H is a histogram-style MACD derivative that the same reader asked to have constructed explicitly alongside MACD-Mo.

The request was not for a new market claim. It was for the missing computation so that each named variant could be formed from price rather than taken on trust.

What the reader asked the series to supply

After reading a treatment of MACD Momentum that did not explain how MACD-Mo and MACD-H are built, the reader requested explicit computation steps for both variants.

The same reader proposed that when an article uses a family of indicators without fully specifying their computation, the missing construction should be supplied as a companion explanation. That practice is construction restatement: reprinting how an indicator is computed whenever a later article assumes that computation.

The reader also asked that mathematically explicit articles continue to appear, arguing that full computation is what distinguishes this kind of venue for quantitatively inclined readers.

What the editorial reply offered instead

The editorial reply said the requested construction information had already appeared in an earlier installment of the same MACD Momentum series. It stated that space limits prevent reprinting standard computations in every later article.

Rather than restating the formulas, the editorial reply referred readers to established textbook treatments of technical-analysis calculations. The later article therefore kept the names MACD-Mo and MACD-H in play while sending the construction elsewhere.

A rebuild test before any signal reading

Editorial view: do not treat MACD-Mo or MACD-H as a signal until a rebuild test is passed. A rebuild test is a check that a named MACD variant can be independently recomputed from the materials at hand before it is treated as a signal.

If the later article names the variant and the earlier installment or a textbook is not in hand, the construction is still missing. Construction restatement would close that gap in the same place the names are used. Pointing away from the article does not, by itself, let a reader form either series from price.

Until MACD-Mo and MACD-H can be rebuilt from the same market series that produces MACD, they remain labels attached to an unfinished construction, not series a reader can verify.
