4H high low, break and entry

This Pine Script indicator identifies the high and low price levels from the 4:00 AM to 8:00 AM trading period and displays them as horizontal lines throughout the day. It detects when price breaks out above the high or below the low after 8:00 AM, marking these breakouts with labeled alerts. When price closes back into the range after a breakout, it displays prominent blue arrow entry signals - down arrows for re-entries from above and up arrows for re-entries from below.
