DCA + Liquidation Levels

The indicator combines a Dollar-Cost Averaging (DCA) strategy after downtrends with liquidation level detection, providing comprehensive market analysis.

📈 Working Principle
1. DCA Strategy Foundation
EMA 50 and EMA 200 - used as primary trend indicators

EMA-CD Histogram - difference between EMA50 and EMA200 with signal line

BHD Levels - dynamic support/resistance levels based on volatility

2. DCA Entry Logic
pinescript
// Entry Conditions
entry_condition1 = nPastCandles > entryNumber * 24 * 30 // Monthly interval
entry_condition2 = emacd < 0 and hist < 0 and hist > hist[2] // Downtrend reversal
ENTRY_CONDITIONS = entry_condition1 and entry_condition2
Entry triggers when:

Specified time has passed since last entry (monthly intervals)

EMA-CD is negative but showing reversal signs (histogram increasing)

Market is emerging from downtrend

3. Price Zone Coloring System
pinescript
// BHD Unit Calculation
bhd_unit = ta.rma(high - low, 200) * 2
price_level = (close - ema200) / bhd_unit
Color Zones:

🔴 Red Zone: Level > 5 (Extreme Overbought)

🟠 Orange Zone: Level 4-5 (Strong Overbought)

🟡 Yellow Zone: Level 3-4 (Overbought)

🟢 Green Zone: Level 2-3 (Moderate Overbought)

🔵 Light Blue: Level 1-2 (Slightly Overbought)

🔵 Blue: Level 0-1 (Near EMA200)

🔵 Dark Blue: Level -1 to -4 (Oversold)

🔵 Extreme Blue: Level < -4 (Extreme Oversold)

4. Liquidation Levels Detection
pinescript
// Open Interest Delta Analysis
OI_delta = OI - nz(OI[1])
OI_delta_abs_MA = ta.sma(math.abs(OI_delta), maLength)
Liquidation Level Types:

Large Liquidation Level: OI Delta ≥ 3x MA

Middle Liquidation Level: OI Delta 2x-3x MA

Small Liquidation Level: OI Delta 1.2x-2x MA

Leverage Calculations:

5x, 10x, 25x, 50x, 100x leverage levels

Both long and short liquidation prices

⚙️ Technical Components
1. Moving Averages
EMA 50: Short-term trend direction

EMA 200: Long-term trend foundation

EMA-CD: Momentum and trend strength measurement

2. BHD Levels Calculation
pinescript
bhd_unit = ta.rma(high - low, 200) * 2
bhd_upper = ema200 + bhd_unit * N // Resistance levels
bhd_lower = ema200 - bhd_unit * N // Support levels
Where N = 1 to 5 for multiple levels
