EMA Channel Key K-Lines

EMA Channel Setup:

1. Three 32-period EMAs (high, low, close prices)
   
2. Visually distinct colors (red, blue, green)
   
3. Gray background between high and low EMAs
   

Key K-line Identification:

1. For buy signals: Close > highest EMA, K-line height ≥ channel height, body ≥ 2/3 of range
   
2. For sell signals: Close < lowest EMA, K-line height ≥ channel height, body ≥ 2/3 of range
   
3. Alternating signals only (no consecutive buy/sell signals)
   

Visual Markers:

1. Green "BUY" labels below key buy K-lines
   
2. Red "SELL" labels above key sell K-lines
   
3. Clear channel visualization
   

Logic Flow:

1. Tracks last signal direction to prevent consecutive same-type signals
   
2. Strict conditions ensure only significant breakouts are marked
   
3. All calculations based on your exact specifications
