Ticker&TapeDaily and weekly charts: why you need both
The same stock can look calm on a weekly chart and chaotic on a daily one. Using both lets you see the forest and the trees.
What changes between the two
On a daily chart each candle or bar is one trading day. On a weekly chart each one sums up a whole week: the Monday open, the highest high, the lowest low and the Friday close. Weekly volume is the total for the five days.
Because a weekly bar condenses five days, it filters out a lot of noise. A scary two-day drop that looks dramatic on the daily may be a small dip inside a strong weekly uptrend.
The weekly chart: the big picture
Start with the weekly. It answers the big questions:
- Is the stock in a long-term uptrend, a downtrend or going sideways?
- Is it forming a proper base, and how long and deep is it? Bases are measured in weeks.
- Are the weekly closes tight (closing at similar prices week after week), a sign that big holders are not selling?
- Is it holding above the 10-week moving average, the weekly cousin of the 50-day line?
The daily chart: timing
Once the weekly looks good, move to the daily to plan the trade. The daily shows the exact pivot, the volume on the breakout day, the 50-day line, and where a sensible stop would go. Daily volume bars also reveal heavy selling or buying days that a weekly bar can hide.
A simple routine: weekly to decide if a stock deserves your attention, daily to decide when to act.
How much history to look at
Too little history hides important context; too much squashes the recent action you need to read.
- Daily chart: about 6 to 12 months. Enough to see the current base and the advance before it.
- Weekly chart: about 2 to 5 years. Enough to see earlier bases, the long-term trend and where the stock sits in its four stages.
- Zoom out further when a stock is near all-time highs or coming out of a long decline.
When the two disagree
Sometimes the daily looks broken while the weekly looks fine, or the other way around. In general the weekly sets the trend and the daily warns you early. A daily break below a key level on heavy volume deserves respect, but one rough day inside a strong weekly base is usually just noise. When in doubt, wait for the next weekly close.
Common mistakes
- Only looking at daily charts and overreacting to normal pullbacks.
- Buying from the weekly chart alone without checking the daily breakout volume.
- Zooming in so far that the base and the prior uptrend disappear.
Key points
- Weekly charts show the trend and the base; daily charts show the timing.
- Look at about a year of daily data and a few years of weekly data.
- The weekly sets the direction, the daily gives the early warnings.
Check what you learned
Answer at least 2 of 3 correctly to complete the lesson.
1. What is the suggested way to combine the two charts?
The weekly shows the trend and the base; the daily shows the pivot, breakout volume and where a stop would go.
2. A stock drops sharply for two days on the daily chart, but the weekly shows a tight base inside a strong uptrend. What does the lesson suggest?
The weekly sets the trend and the daily warns early. One rough stretch inside a strong weekly base is usually noise, unless it is a heavy-volume break of a key level.
3. How much history should you usually look at?
Too little history hides context; too much squashes the recent action. These ranges show the current base and the bigger trend.
