Prior-Period Levels
Prior day/week/month OHLC levels.
What it is
Prior day/week/month OHLC levels.
Prior day high (PDH) and prior day low (PDL) are the highest and lowest traded prices of the previous calendar day. Because they are visible on every chart and used by a huge number of discretionary and algorithmic traders, they function as self-fulfilling reference levels.
Three common uses: as breakout triggers (long if today closes above yesterday's high), as target levels (price often gravitates back to PDH/PDL during the next session), and as liquidity pools (resting stops cluster just beyond them, making them frequent sweep targets).
In 24/7 markets like crypto the 'day' boundary is a convention — UTC 00:00 is most common, but exchange-local midnight is also seen. Pick one and be consistent across signals and backtests.
