Updated T4T Key Liquidity Levels

This indicator maps the key liquidity levels that institutional order flow gravitates toward, all in one clean tool: higher-timeframe highs/lows, killzone sessions ranges with sweep detection, and the opens that anchor intraday bias.
What it plots
HTF Levels - every line anchors at the exact candle that printed the level, keeping charts clean:
Previous Day High/Low (PDH/PDL)
Previous Week High/Low (PWH/PWL)
Monday High/Low (MonH/MonL)
Previous Month High/Low (PMH/PML)
Killzone Sessions with Sweep Detection - Asia session, London session, and New York Session highs/lows, fully configurable. These are treated as resting liquidity. Chose wick-through or closes-through triggers. Optional alerts fire on every sweep.
Opens - Midnight Open and 8:30 Open for intraday dealing-range bias, plus Daily Open, Weekly Open, and Monthly Open, each extending until its period ends.
