Touches = swing highs and lows formed inside the zone. Strength = touches weighted toward recent ones. Volume density 1.0 = the average across the last 500 bars' price range; 2.0 means twice the average volume traded there. Distance is from the current price to the zone's nearer edge.

What this tool does

Support is a price area where declines tend to stall; resistance is where rallies tend to stall. This tool scans a Binance chart for prices where swing highs and lows have clustered, groups them into support and resistance zones, and overlays pivot points from the previous day, week and month (Classic, Fibonacci, Camarilla, Woodie), so you can see the nearest support and resistance to the current price at a glance.

How it is calculated

The last 500 bars are fetched and only closed bars are used (the bar still forming is excluded). 1) Swings: a swing high is a high strictly above the 5 bars to its left and at least as high as the 5 bars to its right; swing lows mirror this (choose 3, 5 or 8 bars per side). 2) Clustering: using ATR(14, Wilder smoothing) at the last closed bar, swings that all lie within 0.5 × ATR of each other form one zone. A zone narrower than 0.25 × ATR is widened around its middle to 0.25 × ATR. 3) Strength: each swing in the zone adds a weight of 0.5 + 0.5 × (bar position ÷ (closed bars − 1)), so the weight runs from 0.5 at the first closed bar to 1.0 at the last, and recent swings count more. Zones are taken strongest first, skipping any candidate that overlaps a chosen one, until 6 are chosen; then, if the nearest price area with at least 2 swings directly below or above the current price is missing, the strongest candidate at that spot replaces the weakest zone (a zone that contains the price, or one already covering the nearest area, is never removed). 4) Volume density = (volume inside the zone ÷ total volume) ÷ (zone height ÷ the full 500-bar price range), assuming each bar's volume is spread evenly from its low to its high. 5) Pivot points use the high H, low L and close C of the previous completed daily, weekly and monthly candle. Classic: P = (H+L+C)/3, R1 = 2P−L, S1 = 2P−H, R2 = P+(H−L), S2 = P−(H−L), R3 = H+2(P−L), S3 = L−2(H−P). Fibonacci: same P; R1, R2, R3 = P + 0.382, 0.618, 1.000 × (H−L), S subtracts the same. Camarilla: R1–R4 = C + (H−L) × 1.1/12, 1.1/6, 1.1/4, 1.1/2, S subtracts the same. Woodie: P = (H+L+2C)/4, R1 = 2P−L, S1 = 2P−H, R2 = P+(H−L), S2 = P−(H−L). A pivot level within 0.25 × ATR of a zone's edge is listed as an overlapping pivot.

Things to know

Frequently asked questions

How are the support and resistance zones found?

Swing highs and lows are found on closed bars, then swings lying within 0.5 × ATR(14) of each other are grouped into a zone. Zones with more and more recent swings score higher. The 6 strongest non-overlapping zones are shown, except that if the nearest area tested at least twice just below or above the price would be left out, it replaces the weakest zone, so distant old levels cannot hide the nearby ones. The bar still forming is excluded because its values keep changing, and a swing is only confirmed once its right-side bars exist, so the last few bars cannot produce one yet.

Which candle are the pivot points based on, and in which time zone?

The previous completed daily, weekly and monthly candles on Binance. Binance candles roll over at 00:00 UTC and weeks start on Monday, so daily pivots refresh at 00:00 UTC. Values computed from candles cut at another time (for example local midnight) will differ.

How do Classic, Fibonacci, Camarilla and Woodie differ, and do they match TradingView?

All four use the previous candle's high, low and close but space the levels differently. Fibonacci multiplies the range by 0.382, 0.618 and 1; Camarilla places tight levels around the close at 1.1/12 to 1.1/2 of the range. Classic here is the formula TradingView's pivot indicator calls Traditional (TradingView's own Classic uses R3 = P + 2(H−L)). Woodie here weights the previous close twice, whereas TradingView's Woodie uses the current period's open, so P can differ. Fibonacci (R1–R3, S1–S3) and Camarilla (R1–R4, S1–S4) match TradingView.

What is volume density?

How much more volume traded inside the zone than the average for the last 500 bars' price range. 1.0 is average; 2.0 means twice as much volume as other price bands of the same height. It is an approximation that spreads each bar's volume evenly across its range, so it differs from a volume profile built from individual trades.

How often does it update, and how is the KRW price calculated?

Every 30 seconds the zones, pivots and nearest levels are recalculated. Fetched candles are briefly cached to limit requests to the exchange, so new bar data arrives every 30 seconds on the 15m chart and every 60–90 seconds on 1H and longer charts and for the daily, weekly and monthly pivot candles. It pauses while the tab is hidden and refreshes as soon as you return. The KRW figure is the USDT price multiplied by Bithumb's USDT/KRW rate (Upbit as a fallback), a reference only; it can differ from Korean exchange prices, which include the kimchi premium.
