Reaction Zones finds levels where price has repeatedly interacted with a pivot point. When a swing high or low is detected, the indicator analyzes how many candles interacted with that level within the surrounding window. If the touch count exceeds your configurable strength threshold, a shaded zone is drawn -representing an area where the market has shown its hand through repeated reactions. Smart duplicate prevention ensures zones don't stack on top of each other, and optional mitigation tracking removes zones when price slices completely through them.
Reaction Zones uses pivot detection to identify swing highs and lows, then counts how many candles within the surrounding detection window have wicks or bodies that interact with each pivot level. The indicator measures candles whose highs penetrate above a pivot low or whose lows dip below a pivot high, counting only candles that opened on the opposite side of the level -- ensuring each touch represents a genuine price reaction rather than a candle that simply passed through.
When the touch count exceeds your configurable Strength threshold, the indicator draws a shaded zone spanning from the pivot price to the nearest cluster of closes. This creates a band rather than a single line, reflecting the real-world area where price has historically reacted. The Length parameter controls the pivot detection lookback, while Strength (1-5) scales proportionally to set the minimum touch requirement.
Smart duplicate prevention checks each new zone against the most recent existing zones. If a new zone would overlap with an already-drawn zone, it is suppressed to keep the chart clean. Optional mitigation tracking monitors whether price has sliced completely through a zone in both directions over consecutive candles, and removes mitigated zones to ensure only active, unbroken levels remain visible.
Dated Reaction Zones charts from the public proof archive: what the indicator marked, and how price behaved around it. No win-rate claims.
Dogecoin 1-hour chart. 4 reaction zones marking the active support and resistance structure. Price is rotating through the pivot levels with clean reactions into the zones.
BNB 1-hour chart. 2 reaction zones identified at significant pivot levels. The zones are framing the active range with visible reactions as price tests each boundary.
EURUSD 1-hour chart. 1 reaction zone marking the active forex pivot level. Price is respecting the level as a clean reaction boundary in the current display window.
Analyzes how many candles interacted with each pivot level -zones are only drawn when the touch count exceeds your strength threshold.
Adjust the Length and Strength inputs to control pivot detection sensitivity and how many touches are required before a zone qualifies.
Optionally removes zones when price completely slices through them, keeping only active zones visible on the chart.
Checks new zones against existing ones to prevent overlapping zones from cluttering the chart.
Practical ways to trade with Reaction Zones.
Enter a trade when price pulls back into a Reaction Zone that has a high touch count, expecting the level to hold based on its proven historical significance.
When price breaks through a Reaction Zone, the old support becomes new resistance (or vice versa). Wait for the retest to enter in the breakout direction.
When multiple Reaction Zones stack near the same price area, the cluster creates a high-probability support or resistance region.
Key settings you can configure in TradingView. See the full setup guide for detailed walkthroughs.
| Parameter | Type | Default | Description |
|---|---|---|---|
| Length | int | 14 | Controls pivot detection sensitivity. Higher values detect fewer, more significant swing points; lower values catch more swings. |
| Strength | int | 3 | Minimum number of touches required for a zone to qualify. Higher values produce fewer but more proven zones. |
| Keep Last X Zones | int | 4 | Maximum number of zones displayed at once. Older zones are removed as new ones form. |
| Keep After Mitigation | bool | true | When enabled, zones remain visible even after price slices through them. Disable to only show active, unbroken zones. |
Keeping the Last X Zones at 3-5 ensures you focus on the most relevant areas. Too many zones create analysis paralysis.
Reaction zones in the direction of the prevailing trend (demand zones in uptrends, supply zones in downtrends) offer higher-probability setups.
The first time price returns to a reaction zone after forming it tends to produce the cleanest reaction. Subsequent retests may see diminishing strength.
Length controls the pivot detection lookback -- how many candles on each side are required to confirm a swing high or low. Higher Length values detect larger, more significant pivots. Strength (1-5) sets the minimum number of candle interactions required before a zone qualifies. It scales proportionally with Length, so a Strength of 3 on a Length of 14 requires more touches than a Strength of 3 on a Length of 7. For most markets, start with Length 14 and Strength 3, then adjust from there.
This setting controls how many of the most recent zones are kept active and extended on the chart. Older zones beyond this count are no longer extended forward, though they remain visible at their original position. The default of 4 keeps the chart focused on the most relevant nearby levels without removing historical context entirely.
When 'Keep Reaction zones alive after mitigation' is disabled, the indicator monitors whether price has completely sliced through a zone -- meaning consecutive candles open and close on opposite sides of the entire zone. When this happens, the zone is considered mitigated (its stored orders have been absorbed) and it is removed from the chart. When enabled, zones persist regardless of how many times price passes through them.
The indicator only marks levels that meet the full qualification criteria: the pivot must be confirmed by the Length parameter, the touch count must exceed the Strength threshold, and the zone must not overlap with an existing zone. If a level appears significant but has no zone, try lowering the Strength setting or adjusting the Length to detect pivots at that scale.
