Prior Day High/Low (PDH/PDL) Rejection & Break
The prior session's high and low are two of the most watched intraday reference levels, and today's price either rejects there or breaks cleanly through, with the two levels not behaving quite the same way.
Call it at the level
A prior session sets the real PDH and PDL. Today's session then plays out bar by bar against those two lines. Every time price enters your tolerance band around either level, the tool pauses and you call Reject or Break before the resolving bar prints, scored against the real wick-and-close outcome.
Setting yesterday's high and low…
| Level | Touches | Correct calls | Accuracy |
|---|---|---|---|
| PDH | 0 | 0 | — |
| PDL | 0 | 0 | — |
| Touch order | Trials | Real reject rate |
|---|---|---|
| First touch | 0 | — |
| Later touch | 0 | — |
How it works
- PDH and PDL are just the prior session's real high and real low. The tool generates a full prior session first, takes its highest high and lowest low, and draws those two numbers forward as fixed reference lines on today's chart.
- A reject is a wick through the level that closes back on the approach side. A break is a real close cleanly through the level. The tool constructs the actual bar that resolves each touch using this exact rule, so the outcome is never arbitrary.
- The tolerance band controls how close counts as a touch. Widen it and price triggers a call more often, including on approaches that would not have felt like a real test of the level at a tighter setting.
- PDH and PDL are tracked as two separate scoreboards on purpose. The generator biases how often each level rejects versus breaks differently for highs and lows, so the two rows in the table are not expected to converge to the same number.
Where this breaks
The first touch of the day is not like the third
PDH and PDL are watched by enough participants that the first test of the day tends to behave differently than a second or third test of the same level. Orders that were resting at the level get used up on the first touch, and by the time price comes back a second or third time there is less resistance left to defend it. The touch-order table on this page is built to make that difference visible in the real tallied data, not just claimed in prose, first-touch and later-touch reject rates should diverge if you play enough trials. A rule that scores well on the first test of a level does not automatically score the same way on the second.
