Beacon Indicator by NinjaTrader Live
Overview
The Beacon indicator is a dynamic support and resistance indicator that uses Bollinger Bands to identify key price levels and divides the Bollinger range into percentage-based zones. The indicator features intelligent line visibility that adapts based on price action.

Core Calculation Logic
Support and Resistance Detection

1. Peak Detection: The indicator identifies pivot highs in the upper Bollinger Band
   • When BB.Upper[1] > BB.Upper[2] AND BB.Upper[1] > BB.Upper[0], a minor peak is detected
   • If this peak exceeds the previous major peak, it becomes the new resistance level
2. Valley Detection: The indicator identifies pivot lows in the lower Bollinger Band
   • When BB.Lower[1] < BB.Lower[2] AND BB.Lower[1] < BB.Lower[0], a minor valley is detected
   • If this valley is lower than the previous major valley, it becomes the new support level
3. Level Reset Logic: When a new major peak/valley is found:
   • New Peak: Support resets to the lowest Bollinger Band value in the lookback period
   • New Valley: Resistance resets to the highest Bollinger Band value in the lookback period

Line 50 Calculation and Changes
The 50 line represents the midpoint between support and resistance:
line50 = bbSupport + (bbResistance - bbSupport) * 0.5

When Line 50 Changes:

• Line 50 changes whenever either support or resistance levels are updated
• When line 50 changes from its previous value, ALL lines become visible and BeaconDir resets to 0
• This ensures traders see the new range structure immediately

Percentage Lines
The indicator divides the support-resistance range into three zones:

• 30 Line: bbSupport + range * 0.3 (30% from support)
• 50 Line: bbSupport + range * 0.5 (midpoint)
• 70 Line: bbSupport + range * 0.7 (70% from support)

Visibility Rules

1. Initial State Reset
   • When line 50 changes value, all lines become visible
   • BeaconDir resets to 0
2. Establishing Direction (BeaconDir = 0)
   • If price breaks below 30 line: Hides 70 line and Resistance
   • If price breaks above 70 line: Hides 30 line and Support
   • Sets BeaconDir = 1
3. Active Trading State (BeaconDir = 1)
   • If price crosses 50 line (from either direction): Resets to show all lines
   • If price exceeds Resistance: Hides Resistance line
   • If price falls below Support: Hides Support line
4. Line Removal Summary
   • 30 Line: Hidden when price breaks above 70 line (bullish bias)
   • 70 Line: Hidden when price breaks below 30 line (bearish bias)
   • Support: Hidden when price breaks below it OR when establishing bullish bias
   • Resistance: Hidden when price breaks above it OR when establishing bearish bias

Override Option
When "Show All Lines" is enabled, all visibility rules are bypassed, and all five lines remain visible at all times.
