<163> 25_0804 Buy-Sell Volume Dynamics

✅ 1. Volatility Analysis Based on WVF (Fear/Greed Detection)
Purpose:

Detect extreme fear (bottom) → Buying opportunity

Detect overheating (top) → Sell warning

How it works:

WVF (Williams VIX Fix) is calculated based on the highest and lowest closing prices

If the WVF exceeds or falls below certain thresholds (sDev, rangeHigh/Low), it is visualized

Outputs are shown as columns: Buy Pressure, Buy Timing, Max Sell Pressure, and Sell Pressure

Application:

Short-term plunge → Potential dip-buying timing

Sharp rise / overbought → Profit-taking or shorting opportunity

✅ 2. Net Buy/Sell Transaction Value Calculation
Purpose:

Confirm real supply-demand dominance

How it works:

Daily transaction value is calculated using average price and volume

Net buy/sell volume is calculated by subtracting previous day’s accumulated volume

If buy volume crosses over sell volume → Buy signal shown via flag

Application:

Strong intraday buy pressure → Entry confirmation

Dominant selling → Use caution or avoid entry

✅ 3. Trend Reversal Line & WaveTrend Analysis
📌 Trend Reversal Line (PRICE_AVG)
Applies a moving average (user-selectable: SMA, EMA, WMA, DEMA, TEMA) to the average of WVF buy/sell columns

Analyzes slope (change) to detect trend reversals
→ Positive slope: Bullish trend
→ Negative slope: Bearish trend
→ Displayed with thick lines for emphasis

📌 WaveTrend (WT) Oscillator
Momentum calculated using Ehler’s WaveTrend method
→ Overbought/Oversold zones marked
→ WT1 > WT2: Bullish momentum
→ WT1 < WT2: Bearish momentum

Application:

Positive PRICE_AVG slope + WT crossover upward → Strong buy signal

Overheated WT + WVF sell pressure → Profit-taking or exit warning

🧠 Strategy Summary
Scenario Entry/Exit Judgment
📉 WVF drops + PRICE_AVG upward slope Buy entry
📈 WVF spike + WT overbought Sell/Exit or hold cautiously
💹 Buy volume > Sell volume crossover Confirm buy momentum
📉 PRICE_AVG downward slope + WT downward crossover Sell reversal / defensive mode

🔚 Summary:
This indicator integrates fear/greed psychology, real transaction flow, trend reversal, and momentum signals into a comprehensive visualization tool. It is particularly effective for intraday and swing traders, allowing identification of high-probability entry points when multiple signals align.
