What it does
The high, low and close of the previous day, week and month are some of the most watched reference prices in trading. They mark where the last completed period found its extremes and where it settled. This indicator draws them on your chart as horizontal lines that start fresh with each new period, with labels at the right edge.
Each group can be toggled on or off, so you can keep a clean chart with only the levels you use.
How it works
- The script requests the high, low and close of the daily, weekly and monthly bars of the current symbol.
- Only completed bars are used. With lookahead off, historical chart bars take the higher-timeframe value offset by one chart bar, and live bars take the previous higher-timeframe bar directly. The result is that a level never changes once its period has begun and is never taken from the future.
- Lines break at the start of each new period so that one day's levels do not join the next day's with a vertical line.
- Daily levels are hidden on daily and higher charts, weekly levels on weekly and higher, and monthly levels on monthly charts, because they add nothing there.
- Alerts fire on closed bars that close above the previous day or week high, or below the previous day or week low.
How to use it
These levels are a simple map of where the market has recently turned or settled:
- Previous day high and low often act as intraday support and resistance. A clean close beyond them can signal a range expansion day.
- The previous close is a neutral reference: price above it means the current period is trading higher than where the last one ended.
- Weekly and monthly highs and lows matter more for swing trading on H1 to H4 charts.
- Many traders watch for false breaks: price pierces the previous day high, fails to hold, and closes back below.
You can combine these levels with the support and resistance lesson's ideas and with your own entry method. Always define a stop-loss before trading a level.

| Show previous week high / low | on | PWH and PWL. |
| Show previous week close | off | PWC (dotted). |
| Show previous month high / low | off | PMH and PML. |
| Show previous month close | off | PMC (dotted). |
| Day / week / month color | blue / purple / orange | Line colors. |
| Show labels on the last bar | on | Names and prices at the right edge. |
Limitations
- The day boundary comes from the data feed. Forex feeds and brokers use different rollover times, so the "previous day" can differ between platforms.
- Some symbols have separate regular and extended sessions; the levels follow whatever the chart's daily bar uses.
- Levels are reference points, not predictions. Price can slice through them, especially around news.
- Alerts cover the daily and weekly high and low only. Monthly levels are visual.
