How the Script Works (Technical Explanation)
・Fixed Starting Price:
The script internally stores the price on the set “comparison start date” (e.g., January 1, 2025).
・Real-Time Calculation:
It constantly retrieves the latest current price and continuously calculates the percentage using the following formula.
Formula: (Current Price - January 1, 2025 Price) ÷ January 1, 2025 Price × 100
*Since January 1 is a global market holiday (New Year's Day) with no prices available, the script automatically adopts the next market opening price (e.g., January 2 morning's open price) as the baseline.
・Automatic label tracking:
The program displays labels like “GOLD” at the right edge of the graph. This ensures you never lose track of which line corresponds to which asset, even when lines overlap.
