BarUtils: Get Bar Index from Date

7월 30일

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.
