streak
Count consecutive bars where condition is true
streak(condition, period)
Parameters
| Name | Type | Description |
|---|---|---|
condition |
boolean expression | The condition to test (e.g., close > open) |
period |
int | Maximum lookback window to check for consecutive occurrences |
Formula
```
Starting from current bar (bar 0), count backwards how many consecutive
bars satisfy the condition, up to a maximum of 'period' bars.
Returns integer from 0 to period:
- 0 = condition false on current bar
- 1 = true on current bar only
- 2 = true on current and 1 bar ago
- ...
- period = true for all bars in window
```Examples
// how many consecutive up days (close > open)?
streak(close > open, 5);
// consecutive days above 50-day MA
streak(close > sma(close, 50), 10);
// consecutive days with volume > average
streak(volume > sma(volume, 20), 7);
// find stocks with 3+ consecutive up days
streak(close > open, 5) >= 3;
// consecutive days where RSI > 50
streak(rsi(close, 14) > 50, 10);
// consecutive narrow range days (true_range < average)
streak(true_range() < sma(true_range(), 20), 5);Returns
Integer: Count of consecutive true conditions (0 to period) ## Notes - Returns 0 if current bar condition is false (streak is broken) - Counts backwards from current bar until condition becomes false - Maximum return value is 'period' (the lookback window) - Useful for identifying sustained trends or patterns - Works with any boolean expression (comparisons, crosses, etc.) ## Related Functions - `rising(field, period)` - Specific case: consecutive increases - `falling(field, period)` - Specific case: consecutive decreases
