ta.highest()Highest Value
Highest value for a given number of bars back.
Syntax
ta.highest(source, length) → series floatArguments
| Parameter | Type | Description |
|---|---|---|
| source | series int/float | Series to scan. |
| length | series int | Lookback length. |
Returns
Highest value in the series.
Remarks
The length-bar window includes the current bar; na values are ignored. The one-argument overload ta.highest(length) uses high. For a breakout against earlier bars, define a prior-bar window explicitly rather than comparing high with a maximum that already includes it.
