High/Low

Previous Day High/Low & Weekly Open Indicator
A clean and simple indicator that displays key reference levels for intraday trading.
Features:

Previous day's high and low levels
Current week's opening price
Auto-hides levels once broken (prevents clutter)
Resets automatically at the start of each trading day
No repainting - uses proper security function calls

How it works:
The indicator plots yesterday's high/low as horizontal lines on your chart. When price breaks above the previous day's high, that level disappears. Same for the low. This keeps your chart clean and shows only unbroken levels.
Perfect for:

Day traders using previous day's range as reference
Breakout trading strategies
Support/resistance analysis
Clean chart setup without manual level drawing

The cyan lines show previous day's high/low, while the orange line displays the weekly open. All levels use non-repainting data for reliable backtesting.
