4 — Night High

It sounds like you're asking about a technical analysis feature or trading pattern named "Night High 4" — though that exact phrase isn't a standard term in mainstream finance. You might be referring to one of these:

1. "Night High" / "Night Low" + "4" (Custom indicator) In some trading communities (e.g., for Forex, crypto, or futures), "Night High" and "Night Low" refer to price extremes during a specific overnight session (e.g., Asian session for EUR/USD). Adding "4" could mean:

4-period moving average of the night high. 4th hour after session open. A 4-bar breakout above the night high.

Feature look :

Plot NightHigh = highest(high, since session start) Alert when price crosses above NightHigh after 4 bars/candles.

2. "Night High 4" as a level (Pivot style) Could be a variation of Camrilla / Floor pivots where:

R4 (resistance 4) = Night high + (Day range * multiplier) Used for breakout entries after Asian session. night high 4

3. Typo for "Night High 4H" (4-hour chart) You may want a feature that:

Marks the highest price during nighttime hours (e.g., 6 PM – 6 AM local) on a 4-hour timeframe. Useful for gap fills or overnight liquidity zones .

4. What kind of "feature" are you building? To give a precise answer, please clarify: It sounds like you're asking about a technical

Platform? (TradingView Pine Script, Python, MetaTrader, Excel) Asset class? (Forex, stocks, crypto) Timeframe? (Minutes, hourly, daily) Is "4" a time, a count, or a multiplier?

If you describe the logic you have in mind (e.g., "from 10 PM to 2 AM, take the highest high, then do X after 4 candles" ), I can write the exact feature code or formula for you.
