count

Count total occurrences of condition in lookback window

count(condition, period)

Parameters

Count - count(condition, period)

Counts how many times a condition is true in the last N bars (including current bar).

  • condition (boolean expression): The condition to test (e.g., close > open)
  • period (int): Lookback window to count occurrences

Formula


Count all bars in the last 'period' bars where condition is true.

Returns integer from 0 to period:
  - 0 = condition false for all bars in window
  - 1 = true on exactly 1 bar
  - 2 = true on exactly 2 bars
  - ...
  - period = true for all bars in window

Examples


// how many of the last 5 days were bullish?
count(close > open, 5);

// count days above 50-day MA in last 10 days
count(close > sma(close, 50), 10);

// count high-volume days in last 7 days
count(volume > sma(volume, 20), 7);

// find stocks with at least 3 up days in last 5
count(close > open, 5) >= 3;

// count days where RSI > 50 in last 10 days
count(rsi(close, 14) > 50, 10);

// count narrow range days in last 5 days
count(true_range() < sma(true_range(), 20), 5);

Returns

Integer: Count of true conditions (0 to period)
