Custom EMA/ATR/Keltner/Bollinger with Squeeze Setup

21-EMA and ATR-Based Analysis
21-EMA (Exponential Moving Average):

Acts as a dynamic support/resistance level.
The price's relationship with the 21-EMA is used to detect trends and potential reversals.
ATR (Average True Range):

Measures volatility.
Used to define price thresholds for buy/sell conditions (e.g., price not more than 1 ATR above 21-EMA for a buy signal).
2. Bollinger Bands and Keltner Channels for Squeeze Setup
Bollinger Bands (BB):

Calculated using a 20-period simple moving average and standard deviations.
Represents high and low volatility zones.
Keltner Channels (KC):

Based on a 20-period EMA and ATR.
Provides narrower channels for price action compared to Bollinger Bands.
Squeeze Condition:

Occurs when Bollinger Bands fall inside Keltner Channels, signaling low volatility.
These periods often precede significant price movements (breakouts).
3. Momentum Indicator (MACD Histogram)
MACD Histogram:
Measures momentum during a squeeze.
Positive histogram values suggest bullish momentum, while negative values suggest bearish momentum.
Used to predict breakout direction from a squeeze.
