A $60 price alert brings you back to Harbor Coffee's chart. Earlier declines stopped near that price. It is tempting to read the alert as “safe again.”
For our fictional Harbor, consider two separate future price sequences. In one, it later closes at $58.
The alert identifies an area to review. The useful question is what would show that area had failed. An alert gets your attention. It does not make the next buyer appear.
A trend is a sequence
A candle shows one interval; a trend takes a sequence.
A swing high is a local peak where a rise turns down. A swing low is a local trough where a decline turns up. Here, each point is a regular-session closing price, with no splits or dividends in either example.
An uptrend has successively higher swing highs and higher swing lows. A downtrend has lower ones of both. In a trading range, prices move back and forth between recurring lower and upper areas.
Take Harbor's closes through session 7: $62, $60, $64, $61, $66, $63, $68. The lows climb from $60 to $61 to $63. The earlier highs rise from $64 to $66.
Both are rising, even though three sessions close lower than the day before. An uptrend has down days.
At session 7, $68 is the highest close so far, but only a candidate swing high. Session 8 closes at $65. That later decline makes $68 a local turning point.
This uses one close on each side to identify a turn; a broader swing takes more observations. A new high is known immediately. A turning point is known later.
Keep the chart interval fixed while comparing swings. A daily decline can sit inside a weekly rise. Changing the interval changes the question.
A zone is a record, not a wall
Support is an area where earlier declines paused or reversed. Resistance is an area where earlier rises stalled or turned down. If the turns happen at nearby prices, a narrow band captures them better than one exact line.
For the second Harbor example, stop at session 6. These are all the closes available:
$60, $66, $61, $66, $60, $66.
Pause here: where would you put the lower and upper zones? What later close would break the lower one?
The lows at sessions 3 and 5 give you a $60–$61 support band. The peaks at sessions 2 and 4 put resistance near $66. Session 6 revisits $66, but it has not turned down yet. You can mark the old zone without pretending the latest visit is a completed reversal.
A close below $60 would break the lower band. That is the evidence to watch for before the next session arrives.
Repeated reactions can reflect investors remembering prices and placing orders around them. This is a possible explanation, not something old closes reveal about the order book. A zone shows where buyers and sellers previously reached a turning point; it cannot tell you who is waiting there next time.
Watch a level change roles
A breakout is a move beyond a previously identified zone. Here, count a breakout when price closes outside the zone.
Sessions 7–10 bring $67, $68, $66.20 and $69. The $67 close breaks above the old resistance area. Price rises again, revisits the area from above at $66.20, then climbs to $69. That revisit is a retest.
By session 10, the retest looks like role reversal: former resistance acting as support. Former support can also become resistance after a downward break. The same price area can interrupt a move from either direction.
Then sessions 11–13 close at $65, $62 and $58. Keep the original zones where they were.
The $65 close falls back into the old range. The last close is $60 − $58 = $2 below the original support band's lower edge. The earlier bounces happened. They did not create a floor.
A false breakout crosses a boundary and quickly returns. A brief intraday move above $66 and back could qualify if you count intraday crossings. Under our closing-price rule, it was never a breakout if it closed inside the range. Waiting for a close changes which moves count, not whether they will last.
Draw before you know the ending
Start with one interval, a few visible swings and one or two zones. Decide what price would contradict the picture before looking ahead. A chart you can never be wrong about is a chart you keep redrawing.
A trendline is a straight line through two or more comparable swings: low to low in a rise, or high to high in a decline. In the first chart, a line through the $60 and $61 lows leaves the later $63 low above it. The line summarizes the slope without needing to touch every turn.
Each description answers a narrower question than a forecast:
| Observation | Careful description | Still unknown |
|---|---|---|
| Higher highs and lows | Uptrend so far | Its duration |
| Tests at $60–$61 | Support area | Orders waiting |
| First close above $66 | Upward breakout | Whether it lasts |
| Close at $58 | Old support failed | Next turning point |
For another try, cover the right half of Fidelity's support diagram. The visible lows must justify your zone before you uncover what followed.
Volume, the shares traded during a period, adds context these closes leave out. The optional chart-patterns lesson examines whether repeated shapes predict anything useful.
Harbor's chart gives you a clear description: “Through session 6, daily closes paused near $60–$61; the $58 close at session 13 means that zone did not hold.” The original zone and the evidence against it both remain visible.
Moving averages offer another way to follow the direction: smooth the closes instead of picking individual turning points.
In short
- An uptrend has higher highs and higher lows at a chosen interval; it still has down days.
- Support and resistance mark places where price reacted before.
- A zone can change roles and still fail later.
- Draw from the information available then, and keep the evidence that proves you wrong.
