QQQ/ES Overlay on NQ

QQQ/ES Overlay on NQ [Pre-Market Fix]
This indicator overlays QQQ or ES price levels onto your NQ chart, dynamically mapping reference levels from your chosen symbol to equivalent NQ prices. Perfect for tracking correlations between Nasdaq futures and related instruments.
Key Features
Dual Symbol Support - Toggle between QQQ and ES with a dropdown. Each symbol uses optimized defaults: QQQ shows every 1 point, ES shows every 5 points.
Pre-Market Ready - Extended session support starting at 4:00 AM ET captures pre-market movement. By 9:00 AM, levels accurately reflect overnight action.
Smart Level Mapping - Calculates real-time ratio between NQ and your overlay symbol, then maps round price levels (like QQQ 614 or ES 5985) to equivalent NQ prices.
Anti-Jitter Technology - Stability threshold prevents lines from shaking on minor movements while maintaining accuracy.
How It Works
The indicator fetches live prices from both QQQ and ES, calculates the dynamic ratio to NQ, and displays mapped reference levels. For example, if NQ trades at 21,500 and QQQ at 614, the ratio is approximately 35.016. This means QQQ 615 maps to roughly 21,535 on your NQ chart.
