Edo PDH/PDL Levels on a one-hour QQQ chart — the previous day high and low in teal and the previous week high and low in gold as dashed labelled lines, with the panel listing each period's levels

1 / 6

Edo PDH/PDL Levels keeps in view the references that intraday and swing traders watch most: the high and low of the previous period. Yesterday's high and low (PDH and PDL), last week's (PWH and PWL) and, if you want them, last month's and last year's are the prices where the prior period found its ceiling and its floor, and where breakout orders and stops tend to pile up. They are objective — they depend on no calculation, only on the real extreme of a closed period — and that is why price keeps coming back to test them: as magnets, as support and resistance, and as breakout zones whose cross signals strength or weakness. The indicator reads each previous closed period, draws its high and low as horizontal lines labelled with their name and exact price, extends them to the right as live references, summarizes every value in a compact panel and alerts when price crosses the day's or the week's extremes. Because the values come from periods that have already closed, they are fixed the moment the period ends and do not repaint. Built for intraday, but useful on any timeframe.

Features

Up to four pairs of previous-period levels, one per higher timeframe: PDH/PDL (previous day), PWH/PWL (previous week), PMH/PML (previous month) and PYH/PYL (previous year)
Day and week on by default, month and year optional and off by default, so the chart stays clean and you add the long-horizon references only when you need them
Each level drawn as a horizontal line labelled with its name and exact price (PDH 726.08), extended to the right with a configurable offset so the labels stay ahead of price
One colour per period — teal for the day, gold for the week, purple for the month and red for the year — so the grade of every reference reads at a glance
Optional 50% midpoint of each previous range (PD 50%, PW 50%, PM 50%, PY 50%), the equilibrium line between the bullish and bearish halves of the range
Compact panel listing the previous high and low per period (D, W, M, Y), with dashes for inactive periods, in any of the four corners, three sizes and Dark or Light theme
Four alerts on the key crosses: Cross above PDH, Cross below PDL, Cross above PWH and Cross below PWL
No repainting: every value is the high or low of a period that has already closed, fixed the moment it ends and constant throughout the current period

Use Cases

Framing the session: while price moves between the PDH and the PDL it is still inside yesterday's range, and the edges of that range are the first references for support and resistance
Reading the cross as strength or weakness — a decisive close above the PDH or the PWH opens the way higher, losing the PDL or the PWL opens it lower — and telling a cross that holds from a sweep that falls back into the range
Giving weight to confluence: when a day level coincides with a week level, or a PDL sits on last week's low, that price becomes a stronger reference
Turning on the 50% midpoint for a mean-reversion read, with the centre of the previous range as a magnet and a pivot between its two halves
Widening the horizon on swing and position charts by enabling the month and year levels, the long-range ceilings and floors the market also keeps in mind

Configuration

Edo PDH/PDL Levels groups its inputs in three blocks. Levels toggles each pair — Previous Day (PDH / PDL, on), Previous Week (PWH / PWL, on), Previous Month (PMH / PML, off) and Previous Year (PYH / PYL, off) — and the Show previous range midpoint (50%) option (off). Style sets one colour per period (Day teal, Week gold, Month purple, Year red), the Line Style (Solid, Dashed — the default — or Dotted), Extend right (on) with a Right offset of 8 bars (0-60) that keeps the labels ahead of price, Show labels (on), the Label Size (Tiny, Small — the default — or Normal) and the Theme Mode (Dark or Light) to match the chart background. Panel turns the information table on or off and sets its Position (Top Right by default, or any other corner) and Size (Tiny, Small or Normal). The defaults are calibrated for intraday, with the day's and week's levels; for a wider perspective enable the month and year, and for a mean-reversion read, the 50% midpoint.
