BarUtils: Get Bar Index from Date
Library "BarUtils"
getBarIndexFromDate(targetTimestamp)
Parameters:
targetTimestamp (int)
**Description**:
This utility provides a reliable way to calculate the `bar_index` of a specific calendar date, regardless of chart resolution. It's especially useful for anchoring scripts to historical events, labeling macroeconomic moments, or marking custom time-based signals that must remain consistent across timeframes.
Unlike hardcoded `bar_index - N` approaches, this function dynamically estimates the number of bars between a given `timestamp()` and the current bar using the actual time-per-bar (`time - time[1]`). It works correctly on intraday, daily, weekly, and monthly charts.
### 💡 **Function Provided**:
import TradeTitan120/BarUtils/1
* `getBarIndexFromDate(int targetTimestamp)`
→ Returns the estimated `bar_index` that aligns with a given timestamp
### ✅ **Use Cases**:
* Marking past events like FOMC meetings, market crashes, or personal signals
* Backtesting entry/exit conditions from specific calendar dates
* Anchoring visual elements (shapes, lines, labels) across resolutions
This tool is simple, fast, and built for accuracy. Use it to enhance multi-timeframe compatibility in any script.
