Channel Trading

Channels define parallel price boundaries for trading bounces or anticipating breakouts.

Pattern Structure

Ascending Channel (Bullish)

• Both lines slope upward — buy at lower line, sell at upper
• Break below = reversal signal

Descending Channel (Bearish)

• Both lines slope downward — sell at upper line, cover at lower
• Break above = reversal signal

Horizontal Channel (Range)

• Parallel horizontal lines — classic range trading
• Break either direction = new trend

Workflow

1. Get Swing Point Data

Fetch exact timestamps and prices for swing highs/lows (need 2+ per line):

get_candles_around_date(symbol=<symbol>, exchange=<exchange>, interval=<interval>, date=<swing_date>)

2. Draw the Channel (2 parallel trend lines)

Draw both channel boundaries as separate trend lines in parallel calls:

# Upper channel boundary (connecting swing highs)
draw_chart_analysis(action="create", drawing={
    "type": "trend",
    "points": [
        {"time": <high1_time>, "price": <high1_price>},
        {"time": <high2_time>, "price": <high2_price>}
    ],
    "options": {"text": "Channel R"}
})

# Lower channel boundary (connecting swing lows)
draw_chart_analysis(action="create", drawing={
    "type": "trend",
    "points": [
        {"time": <low1_time>, "price": <low1_price>},
        {"time": <low2_time>, "price": <low2_price>}
    ],
    "options": {"text": "Channel S"}
})

3. Confirm and Enter

Channel Bounce: Wait for price at boundary + reversal candle + RSI divergence via get_indicators(indicator_code="rsi", symbol=<symbol>, exchange=<exchange>, interval=<interval>). Stop beyond boundary.

Channel Breakout: Wait for candle close outside channel. Confirm with get_indicators(indicator_code="mfi", symbol=<symbol>, exchange=<exchange>, interval=<interval>) for volume. Target = channel width projected from breakout. Mark breakout level:

draw_chart_analysis(action="create", drawing={
    "type": "breakout",
    "points": [
        {"time": <break_time>, "price": <break_price>},
        {"time": <target_time>, "price": <break_price>}
    ],
    "options": {"text": "Breakout"}
})

Evidence and Validation

• Treat the setup as a testable hypothesis, not a prediction. Define thresholds, entry, invalidation, and exit before evaluating outcomes.
• Calibrate on the same instrument, venue, session, and timeframe. Use closed candles and a held-out or walk-forward sample; record every variant tried.
• Include spread, fees, slippage, borrow or funding, partial fills, and latency. Reject the setup when net expectancy is not positive or depends on one narrow parameter.
• Return observed inputs, missing data, cost assumptions, entry, invalidation, exit, and a valid, watch, or no-trade status.
• Research basis: Lo, Mamaysky & Wang found that some objectively defined chart patterns contain incremental information, while emphasizing that visual pattern recognition is subjective.

Key Rules

• Minimum 4 total touch points (2 per line) to validate a channel
• Trade WITH channel direction: buy support in ascending, sell resistance in descending
• Channel midline acts as interim S/R — price rejecting at midline signals weakening momentum
• Stop applying the fade rule after its predeclared closed-bar breakout invalidation.
• Record incomplete boundary traversals as a feature; do not declare weakening without tested evidence.
