Capital41 PDH/PDL Levels

// Copyright (c) 2026 Capital41 | MIT License
// CAPITAL41 PREVIOUS DAY/WEEK/MONTH LEVELS v3

// What it does:
// - Plots Previous Day High/Low (PDH/PDL) with midpoint.
// - Optional Previous Week High/Low (PWH/PWL) with midpoint.
// - Optional Previous Month High/Low (PMH/PML).
// - Right-edge labels for quick identification.
// - Alerts when price touches or breaks key levels.
//
// v2 changes (expanded from 43-line original):
// - ADDED: Midpoint levels for daily and weekly ranges.
// - ADDED: Previous month high/low.
// - ADDED: Right-edge labels on all levels for easy identification.
// - ADDED: Optional fill between high/low levels.
// - ADDED: Alert conditions for touch and breakout of each level.
// - ADDED: Status badge showing distance to PDH/PDL and position in range.
// - ADDED: User-configurable colors for each timeframe.
//
// v3 changes:
// - FIXED: Touch and breakout conditions gated by barstate.isconfirmed, so
//          alerts fire on bar close instead of repainting intra-bar.
//
// TradingView setup:
// 1) Open TradingView -> Pine Editor.
// 2) Paste this script, Save, and Add to chart.
// 3) Use 30m or 4h on BTC or US stocks.
//
// Usage guide (30m/4h):
// - PDH/PDL act as natural liquidity targets and reversal zones.
// - Midpoints often serve as intraday support/resistance.
// - PWH/PWL and PMH/PML frame larger range context.
// - Combine with sweeps and confluence signals for higher confidence.
