Use the Market Activity boards
Updated 31 October 2026 · 4 min read · 14 Contents
Plain-language meaning
Market Activity groups the session's movers into boards for an exchange and universe: top gainers and losers, most traded, high-volume movers, 52-week highs and lows, price and volume shockers, circuit watch, sector heatmap and breadth, and turnover. Every board describes what already happened in the session.
Why it is useful #
It lets a user scan one exact universe, such as Nifty 500 or the S&P 500, for unusual moves and turnover without building a screen, then open the listing to inspect the evidence behind a move.
Where it appears and the workflow #
Open Market Activity (/market/activity), choose the exchange (NSE, BSE, NASDAQ, NYSE, AMEX, HKEX or SGX) and universe, then pick a board. Each board has a symbol or name filter, a 'Showing x of y' count, CSV export and click-to-sort columns. Sector tiles and breadth rows open a detail panel. Auto-refresh every 60 seconds is on by default and skips reloads while the market is closed. Turnover has its own market, segment, daily or monthly, and 30/90/365-day controls with numbered source links.
Calculation or source #
Rows are built from persisted session bars for the selected universe. Relative volume is session volume divided by the trailing 20-session average volume. Distance below the 52-week high is (52W high − close) ÷ 52W high × 100 and distance above the 52-week low is (close − 52W low) ÷ 52W low × 100. Price shockers rank by the absolute change percentage, and value traded is close × volume.
Prerequisites, inputs, period and unit #
Prerequisites are a supported exchange and a universe that has stored bars for the session. Prices are in the venue's native currency, change is in percent and price units, volume is shares, and the 52-week and relative-volume figures need enough history; rows without it are unavailable.
Worked example #
Illustrative only: a listing closing at 105 with a 52-week high of 120 is 12.5% below its high. If it traded 3.0 million shares against a 20-session average of 1.2 million, its relative volume is 2.5×. Both describe the session; neither says the move will continue.
What high and low mean #
A high relative volume means the session was busier than its own recent average, and a listing near its 52-week high has traded close to the top of its one-year range. Sector breadth shows how many constituents rose or fell, not how much money moved.
Positive, negative and zero #
Positive change means the close is above the previous close and negative means below. A zero change is a real unchanged close. Gainers and losers are relative to the previous session only and are not ranked by quality.
Limitations and common mistakes #
Boards rank by one measure and ignore liquidity, news and corporate actions, so a thin listing can top a shockers board on a small trade. The universe filter does not apply to Turnover. HKEX and SGX prices show a dash when the venue currency symbol is unknown. A common mistake is comparing a gainer on one exchange with a gainer from another universe.
Market-specific differences #
NSE and BSE offer index universes such as Nifty and SENSEX families, while US venues offer Nasdaq-100, S&P 500 and Dow 30 filtered to the selected venue's listings. Session timing and holidays follow each exchange's own calendar.
Suggested next steps #
Choose NSE and the Nifty 500, open High Volume Movers and record the top relative-volume row. Open its Market Details page, check the session date and news, then compare the same listing's position on the 52W High board and explain what each board measures.
