Sector SPDR ETFs

This script automatically identifies the SPDR sector ETF that corresponds to the currently viewed US stock ticker. It maps over 500 US-listed stocks to their respective SPDR sector ETFs — such as XLK (Technology), XLF (Financials), XLY (Consumer Discretionary), and others — based on pre-defined symbol lists.

When applied to a chart, the script displays a label below the last candle showing the SPDR sector symbol (e.g., "XLE" for Energy stocks like XOM). This allows traders and investors to quickly understand the sector classification of any stock they analyze.
