TradingView unusual volume screening

Build the Stock Screener shortlist

1. Open Products → Screeners → Stocks. Select the market and exchanges you intend to research. Keep stock type and currency consistent with your thresholds.
2. Add Price and Average Volume filters. For the demonstration, use Price above $5 and Average Volume (30 days) above 500,000 shares.
3. Add Relative Volume, open its settings, choose the daily interval and enter above 2. Add the same field as a visible table column.
4. Display symbol, exchange, price, daily volume, average volume and relative volume. Sort Relative Volume descending, then record the scan time, interval and session.
5. Open each surviving chart. Check the exchange, data timestamp, news, spread and price structure before saving the candidate. Save the screen so the rules can be repeated.

The official screener walkthrough covers filters, column settings and saved screens. Interface labels can vary by market.

Four inputs, one candidate to investigate

All symbols and values below are invented. Assume a completed daily session with valid volume history. M means million shares; the RVOL calculation uses the previous ten daily bars. The 30-day average is a separate supplied input.

DEMO-B has the largest ratio but fails the liquidity floor. DEMO-A passes all three numeric rules; it can still be rejected after chart review. For example, a hypothetical $23.90 bid and $24.10 ask imply a $0.20 spread, or 0.83% of the $24 midpoint, before fees or slippage.

Use Pine Screener for a custom rule

Stock Screener cannot run this code. In the separate Pine Screener, select a watchlist or index, choose the saved indicator, set the interval, and scan. Filter Previous-bar match above 0.5. The script also colors confirmed unusual-volume chart bars and can label their ratios.

The outputs deliberately refer to the preceding completed bar, so they lag the live bar by one interval. With length 10, a previous bar of 3.30M and its prior-ten average of 1.10M produce 3.00 and a match of 1. A missing or zero baseline produces no ratio. This is a bar-based demonstration, not a same-time-of-day indicator.

//@version=6
indicator("Unusual Volume Review [Pineify]", overlay=true)

int length = input.int(10, "Prior-bar volume average length", minval=1, maxval=100)
float threshold = input.float(2.0, "RVOL threshold (strictly above)", minval=0.1, step=0.1)
bool showLabels = input.bool(true, "Label confirmed unusual-volume bars")

float priorAverage = ta.sma(volume, length)[1]
float rvol = not na(volume) and not na(priorAverage) and priorAverage > 0 ? volume / priorAverage : na
bool unusual = not na(rvol) and rvol > threshold
bool confirmedUnusual = unusual and barstate.isconfirmed

barcolor(confirmedUnusual ? (close >= open ? color.green : color.red) : na)
if confirmedUnusual and showLabels
    label.new(bar_index, high, "RVOL " + str.tostring(rvol, "#.##"), yloc=yloc.abovebar, style=label.style_label_down, textcolor=color.white)

// Pine Screener columns use the preceding completed bar.
float closedRvol = rvol[1]
float closedMatch = na(closedRvol) ? na : (closedRvol > threshold ? 1.0 : 0.0)
plot(closedRvol, "Previous-bar RVOL", display=display.data_window)
plot(closedMatch, "Previous-bar match", display=display.data_window)

Use matching chart and scan sessions; the script does not force regular hours. Pine Screener uses one indicator per screen and the most recent 500 bars. Its table displays the chosen indicator's plots. Account access, feed differences and runtime behavior still need checking in TradingView. Read the Pine Screener guide and current requirements.
