Features

• Two draw modes: color-coded HA candles (OHLC with proper High/Low) or smoothed color line overlay
• Five smoothing methods: SMA, EMA, Double-Smoothed EMA (Vervoort-style DEMA), SMMA, and LWMA — all with configurable period
• Step filter: noise reduction in pips — ignores HA changes smaller than a configurable threshold (like mladen’s, but on top of 5 smoothing methods)
• Signal arrows: Wingdings arrows (▲/▼) plotted on chart at every color change — configurable arrow codes and offset
• Multi-Timeframe (MTF): display higher-timeframe HA data mapped onto current chart
• Full HA calculation: proper recursive HA Open, High, Low, Close
• Consecutive bar counter: tracks streak of same-color bars in real time
• Strength meter: body-to-range ratio with visual bar (████░░░░░░) and percentage
• HA Delta: shows Close − Open difference with signed color
• Dashboard panel: 9 data rows — Trend, Smoothing, Step Filter, HA Close, HA Open, HA Delta, Consecutive, Strength %, Strength Bar
• 4-channel alerts: popup, sound (custom file), push notification, and email on color change
• Fully customizable: 8 input groups, 30+ inputs — colors, dashboard position/fonts, arrow codes, everything configurable
• Clean chart management: all objects use the EXHA_ prefix for safe removal
