KING_HPM_LPM_SPY

Name: KING_HPM_LPM_SPY

This indicator identifies and plots the high (HPM) and low (LPM) of the pre-market session for the SPY ticker (or any chart it's applied to), based on the New York timezone (04:00 - 09:30 AM).

Functionality:

Tracks the high and low during the premarket hours.

When the premarket ends (09:30 AM NY time), it draws horizontal lines at the premarket high and low levels.

It also adds labels:

"HPM" for the high

"LPM" for the low

These lines and labels are customizable (style, width, color).

It keeps the plotted lines/labels for a user-defined number of days (default = 2).

If the number of stored days exceeds the limit, it automatically deletes the oldest lines and labels to maintain only the most recent days visible.
