Apex Indicator

The Apex Indicator is a physics-based momentum tool designed to measure the 2nd Derivative (Acceleration) of both Price and Volume.

​Unlike standard oscillators which often lag, this indicator uses Kinematics to identify the subtle shifts in momentum before price makes a major move. It answers the critical questions: Is the selling pressure fading? and Is there fresh fuel (Volume) entering to support a turn?

​This script uses Hull Moving Average (HMA) smoothing for low-latency calculation, and Z-Score Normalization to force Price and Volume onto a shared, readable scale.

​Visual Guide
​The Histogram (Price Acceleration)
​Bright Green: Strong Bullish Acceleration (High Velocity).
​Dark Green: Developing Bullish Momentum (or Waning Bullishness depending on context).
​Bright Red: Strong Bearish Acceleration (Panic/Dump).
​Dark Red: Developing Bearish Momentum (or Waning Bearishness).

​The Line (Volume Acceleration)
​Yellow: Volume is accelerating (Interest is entering).
​Purple: Volume is decelerating (Interest is leaving).

​The Background Highlights
​Green/Red Background: These mark Statistical Extremes (>1 Standard Deviation). While these show maximum power, they often mark the climax of a move rather than the start.

​How to Trade: Reading the Subtleties
​The power of the Apex Indicator is not in chasing the spikes, but in reading the Transitions.

​1. The Turn (The Reversal Entry)
Don't wait for the explosion; look for the "braking" action.
​The Setup: Price has been moving down strongly (Bright Red bars).
​The Signal: The histogram shifts to Dark Red and begins moving up toward the zero line (less negative). This means the selling acceleration is dying.
​The Trigger: A Dark Green bar prints, accompanied by the Volume Line turning Yellow/Rising.
​Why it works: You are entering when the bearish energy is exhausted and fresh volume is stepping in to lift the price, often before the main breakout occurs.

​2. The Second Wind (Trend Continuation)
​The Setup: You are already in a trend (Green bars), but the bars fade to Dark Green or near Zero (a pullback or pause).
​The Trigger: The next bar flips Bright Green and the Volume Line spikes Yellow.
​Why it works: This confirms that the pause was just a breather, and buyers are stepping back on the gas.

​3. The "Hollow Move" (Trap Avoidance)
​The Scenario: Price is moving up (Green bars), but the Volume Line is Purple or dropping.
​Interpretation: This is a drift, not a drive. Without volume acceleration support, these moves are prone to rapid reversal.

​4. The Climax (Exits)
​If the Background flashes Green (Alert Trigger), be aware that price acceleration has hit a statistical extreme (Z-Score > 1).
​If you are in a position, this is often a good place to Take Profit, as maintaining that level of acceleration is mathematically difficult for the market to sustain.

​Settings
​Analysis Length (21): The lookback period for the HMA smoothing.

​Normalization Lookback (21): The historical window used to calculate the Z-Score. A setting of 21 allows the indicator to self-adjust quickly to recent volatility conditions.
