What is a range breakout?
A trading range is an area between a lower price level, or support, and an upper level, or resistance. A breakout occurs when price moves beyond a boundary. This guide focuses on breakouts confirmed by a candle close.
One way to draw a range is to use the highest high and lowest low over a set number of candles. This is the basis of a Donchian channel. CoinScreener compares the latest close with the range of the previous 30 daily candles, excluding the candle being checked. A chart's default channel settings may differ.
For this alert, a wick above the boundary is not enough: the candle must close above it. A close confirms that the rule was met, not that the move will continue. If candles are unfamiliar, start with candlesticks and timeframes.
Range breakout
CoinScreener's Range Breakout requires a daily close strictly above the highest high of the previous 30 days, including weekends. It must clear the previous wicks as well as the previous closes. A close exactly at the old high does not qualify.
The rule does not require a flat, sideways market first: a market already rising can also make a new 30-day high. The alert includes the distance above the old range top and a volume z-score, explained below. High volume is not required for the alert to trigger.
CoinScreener currently alerts only the upward version on the daily timeframe. The downward example in this lesson is included to explain the chart pattern.
Watch the range change
Select Break holds, Break fails or Break down, then step through the candles. This illustration uses a shorter, 10-candle range so the examples fit on one chart. The product uses 30 daily candles.
The dashed lines show the range used to assess the latest revealed candle. On the next step, that candle joins the range and the oldest one drops out. A line can move when a new high or low enters the window, or when an old extreme leaves it. Note the original boundary when the first break occurs; the rolling line will move afterwards.
A range with a top and a bottom
The dashed lines show the highest high and lowest low of the previous 10 candles. Each step adds the newly completed candle to the next range and removes the oldest one. CoinScreener uses 30 daily candles.
Illustrated walkthrough · all scenarios
Break holds
- A range with a top and a bottom. The dashed lines show the highest high and lowest low of the previous 10 candles. Each step adds the newly completed candle to the next range and removes the oldest one. CoinScreener uses 30 daily candles.
- A close above the range. The candle closes above the old range top. Note this boundary before advancing: the range line will update on the next step. The larger volume bar shows more trading, not a guaranteed continuation.
- Check the original boundary. Compare price with the boundary at the first breakout, not just the updated dashed line. A return to that old level is a retest. Has price stayed beyond it or moved back inside?
- The move continues here. Price keeps going in this hypothetical case. That was not known at the break. Compare the failed example before treating a breakout as an entry on its own.
Break fails
- A range with a top and a bottom. The dashed lines show the highest high and lowest low of the previous 10 candles. Each step adds the newly completed candle to the next range and removes the oldest one. CoinScreener uses 30 daily candles.
- A close above the range. The candle closes above the old range top. Note this boundary before advancing: the range line will update on the next step. The larger volume bar shows more trading, not a guaranteed continuation.
- Check the original boundary. Compare price with the boundary at the first breakout, not just the updated dashed line. A return to that old level is a retest. Has price stayed beyond it or moved back inside?
- Back inside the range. Price is back inside the original range. This example began with the same upward breakout candle as Break holds, but the outcome differs. Compare it with the exit condition in your plan.
Break down
- A range with a top and a bottom. The dashed lines show the highest high and lowest low of the previous 10 candles. Each step adds the newly completed candle to the next range and removes the oldest one. CoinScreener uses 30 daily candles.
- A close below the range. The candle closes below the old range bottom. This is a downward breakout example; CoinScreener currently alerts only upward daily breakouts. The larger volume bar shows more trading, not a guaranteed continuation.
- Check the original boundary. Compare price with the boundary at the first breakout, not just the updated dashed line. A return to that old level is a retest. Has price stayed beyond it or moved back inside?
- The move continues here. Price keeps going in this hypothetical case. That was not known at the break. Compare the failed example before treating a breakout as an entry on its own.
The two upward examples share the same breakout candle. In one, price stays above the original boundary; in the other, it falls back inside. A retest is a return to the broken level. A breakout can continue without a retest, and a retest can fail.
What it shows about the market
A qualifying close tells you that price finished the day above every high in the preceding 30 daily candles. It does not show who traded, why price moved, or how much buying or selling remains.
Volume adds context about the amount traded. A larger volume reading does not reveal the number of traders involved or guarantee that price will hold above the range.
Which timeframe should I use?
CoinScreener supports Range Breakout on 1D, meaning one candle per day. Read the daily chart first, then check a weekly chart for earlier highs that may be outside the 30-day window.
A 30-candle range on a four-hour chart covers five days, so it will not reproduce this alert. Match the market, exchange, timeframe and lookback when comparing charts.
How to use it practically
- Mark the broken level. Record the range top at the alert candle, rather than using the later, updated boundary.
- Read the volume evidence. Check whether volume was above or below its recent baseline. Treat this as context, not a pass-or-fail test for an entry.
- Check the price available now. Decide whether your plan calls for an entry after the break, a retest, or no trade. The alert close may no longer be available.
- Find the next obstacle. Look for earlier highs above the break and measure how much room remains before them.
- Define an exit and size. Decide what would invalidate the idea and compare the possible loss with the room to your intended exit. Include fees and execution costs; the risk guide explains the calculation.
For example, suppose the previous 30 days had a high of 50 and a low of 40, and the next day closes at 52. An entry at 52, planned stop at 49 and target at an older high of 58 would risk 3 price units to seek 6: 2:1 reward-to-risk before costs. If the target were 54, that ratio would fall to about 0.67:1. Neither ratio tells you how likely the target is to be reached.
When to wait or skip
Consider waiting when the daily candle is still open, price has moved beyond your planned entry, or you cannot identify a suitable exit. Repeated failed breaks and low volume are reasons to examine the context more carefully, not proof of what happens next.
If your plan treats a close back inside the range as failure, decide how much loss you can tolerate while waiting for that close. A close-based exit and a stop order at a fixed price behave differently, and neither guarantees an exact loss.
Reading it in CoinScreener
Open Alerts, select Range Breakout in the Alert type filter and choose 1D in the signed-in feed. Open a matching alert and read:
- Range top: the highest high of the previous 30 daily candles.
- Above the range top: the close's percentage distance above that level. A close of 52 above a range top of 50 gives 4%.
- Volume (z-score): how far the day's traded volume is from its recent average, measured in standard deviations. A positive score means above-average volume; a negative score means below-average volume. A score of 2 means two standard deviations above the average, not twice the volume. It does not measure the chance of success.
The market-context chart draws the range top and bottom alongside the candles. Read the boundary at the alert candle, then compare the price available now with the entry and exit you are considering.
A recorded 4USDT daily Range Breakout with populated candles, range boundaries and volume. The trigger close is 8.68% above the prior range top of 0.0218, and the volume z-score is 2.87. Read the range boundary at the trigger candle. This is a historical replay example, not a live notification.
A quick checklist
- I am using the daily chart and the previous 30 candles.
- The daily close cleared the old range high, including its wicks.
- I have read the volume z-score without treating it as a guarantee.
- I know the available entry, next obstacle and planned exit.
- My position size and possible loss fit my risk budget.
Common questions
Does a breakout mean buy? No. It means a daily close cleared the previous 30 daily highs. You still need an entry, exit and position size that fit your plan.
Why are downward breakouts not alerted? They did not meet CoinScreener's historical screening checks. That explains the current selection; it does not prove downward breakouts are never useful.
Why is this only on the daily chart? In the recorded study, the four-hour version's apparent advantage disappeared when its three strongest symbols were removed. The daily version passed the checks. This study measured later price changes, not a complete trading strategy with stops, position sizing and costs. Passing it does not guarantee future profits.
