Large Scale Activity Detector

🧠 What It Is:
An institutional footprint detector — it finds bars with unusually high volume and range relative to recent averages (using z-scores).

⚙️ How It Works:

Computes z-scores of volume and range relative to a moving 20-bar average and standard deviation.

Triggers when both z-scores > 2 (2σ = statistically significant spike).

Confirms trend bias with EMA(50):

If close > EMA → only detect bullish spikes.

If close < EMA → only detect bearish spikes.

Float sensitivity parameter lets you adjust for low-float vs. high-float stocks.

📈 How to Use It:

When yellow (large buy) bar prints → institutional buying surge.

When navy (large sell) bar prints → institutional selling surge.

If it aligns with Supertrend + Squeeze direction = strong follow-through probability.

Avoid taking trades against LSAD; it often reveals liquidity pushes or exhaustion points
