Malama's KAYCAP Pre-Market Box

# Pre-Market Single Candle Range Box

## What Makes This Script Original

While many scripts plot entire pre-market session ranges, this indicator focuses specifically on **a single user-defined candle** within the pre-market period rather than the entire session. This targeted approach allows traders to isolate the most relevant price action from a specific time (default: 4:00 AM EST) that often establishes key levels for the trading day.

## Core Methodology & Technical Implementation

**Single Candle Isolation:**
- Captures OHLC data from one specific minute within pre-market hours (user configurable)
- Differentiates between the candle's body (open/close range) and wicks (high/low extremes)
- Creates four distinct reference levels instead of traditional session high/low boxes

**Dual Box Structure:**
- **Inner Box (Body):** Plots the range between open and close prices of the target candle
- **Outer Boundaries:** Separately plots the high and low of that same candle
- **Visual Differentiation:** Uses different colors and line weights to distinguish body vs. wick levels

**Time-Specific Logic:**
The script uses precise time matching (`hour == boxHour and minute == boxMinute`) to capture data from exactly one candle, rather than aggregating an entire session. This creates four specific price levels:
- Box Top: Higher of open/close (body boundary)
- Box Bottom: Lower of open/close (body boundary)
- Box High: Candle high (wick extreme)
- Box Low: Candle low (wick extreme)

## Why This Approach Differs from Standard Session Boxes

**vs. Full Session Ranges:** Focuses on a single critical minute rather than entire pre-market period
**vs. Traditional S/R:** Creates both body and wick levels from one specific candle
**vs. Opening Range:** Uses pre-market data rather than regular session opening minutes

## Practical Application

The 4:00 AM EST default targets a time when institutional pre-market activity often establishes initial sentiment and key levels. By isolating this specific candle's range:

- **Body levels** often act as initial support/resistance during regular hours
- **Wick extremes** provide broader range boundaries for breakout analysis
- **Precise timing** allows focus on the most statistically relevant pre-market moment

## Technical Considerations

- Requires intraday timeframes (1-minute recommended) to capture specific candle data
- Time settings should match your broker's timezone for accurate candle selection
- Works best on liquid instruments where pre-market activity is meaningful
- The selected candle must exist in your data feed for the levels to plot

## Customization Options

All timing parameters are adjustable:
- Target candle hour and minute
- Pre-market session definition (for context)
- Visual styling for all four level types

This focused approach provides more granular analysis than broad session ranges while maintaining simplicity in execution.
