Filtered swing ledger for MW pattern construction
A historical swing ledger locks a reversal-filter, carries one wave-label and one live-apex, and forms a rank-code only after five dated turning prices are retained. Wave-span and percentage change print only on the bar that ends the current designation.
- Date, open, high, low, and close occupy the first five data fields, and a named reversal-filter cell, shown at 0.01, sets how far a contrary high or low must travel before the wave-label may flip.
- The live-apex starts at the first high, then follows the running high of an upwave or the running low of a downwave, and resets when the wave-label changes.
- Wave bookkeeping keeps the start date, the date the current live-apex was made, the last date the present wave-label still applied, the inception-price, and the ending-price written when the label flips.
- Five mw-pattern-points are ranked inside that same set to form one rank-code. Wave-span and the percentage change from inception-price to ending-price print only on a bar that ends the current designation.
What the ledger records
The construction is a dated swing ledger. It keeps a wave-label, one live-apex, and a short list of completed turning prices so a later rank-code can be rebuilt from the same fields.
Fields and the reversal-filter
Date, open, high, low, and close occupy the first five data fields. A named filter cell, shown at 0.01, is the reversal-filter: a named percentage applied to the live-apex so an opposing high or low must travel a stated distance before the wave-label may flip.
Wave-label and live-apex
An initial wave-label is set to up. Later bars keep that up or down wave-label unless a contrary high or low qualifies a switch.
The live-apex is the extreme of the wave still in force. It starts at the first high and thereafter follows the running high of an upwave or the running low of a downwave, resetting to the new extreme when the wave-label changes.
The direction-change-threshold
A direction-change-threshold is the live-apex scaled by one minus the reversal-filter during an upwave and by one plus the reversal-filter during a downwave. That level is used as the mark that would confirm a new designation.
Bookkeeping across a label change
Wave bookkeeping records a start date carried from the prior apex date, the date the current live-apex was made, the last date the present wave-label still applied, an inception-price taken from the prior apex, and an ending-price written when the wave-label flips.
The inception-price is the apex value that begins the newly designated wave and is held until the wave-label changes again. The ending-price is the last apex value written when the market leaves the current designation.
Five turning prices and the rank-code
The latest live-apex is stored as the first of the mw-pattern-points. Each completed wave-label change shifts prior apexes back so the second through fifth most recent turning prices remain available.
Those five turning prices are ranked within the same five-value set and joined into one rank-code. The rank-code concatenates how those five apexes rank against one another, encoding which turning prices stand higher or lower, and it represents the current MW configuration.
What prints when a designation ends
Only on a bar that ends the current designation does the construction report wave-span: net working days from the wave start date to the date the live-apex printed, with an optional holiday argument. The same completed bar also records the percentage change from inception-price to ending-price.
