I need a Pine Script for TradingView tailored to the Indian market. The script should draw lines on the current day's chart based on custom levels sourced from the previous trading day. These levels will be defined using specific price points, which must be fetched automatically from past trading data. The deliverable should be a clean and functional Pine Script that seamlessly integrates with TradingView. It’s important that the script is optimized for performance and complies with TradingView's scripting standards.
