Key Levels: Prior Open & Close (D/W/M/Q/Y)

This indicator plots the previous period's open and close levels for multiple timeframes—daily, weekly, monthly, quarterly, and yearly—on your chart. It uses Pine Script's request.security() function to pull the prior period's open and close prices for each timeframe, then draws horizontal dotted lines extending to the right at those levels. Each line is labeled and color-coded for easy distinction. These levels can help highlight potential support/resistance areas, but they are reference points only and not trading signals.
