Horizontal S&R gives you price levels. Trendlines give you direction. In an uptrend, the trendline connects successive higher lows (dynamic support). In a downtrend, it connects successive lower highs (dynamic resistance).
Angle Matters
30-45 degree angles represent sustainable trends. 60+ degree angles are unsustainable momentum that corrects sharply. Steeper = less reliable.
A channel forms when two parallel trendlines create a corridor that price bounces between.
A break occurs when price closes beyond the line (not a wick poke).
Channel breakout target: Measure the channel height and project that distance from the breakout point. A $10-wide channel breaking above at $80 targets $90.
False Breaks
Trendlines generate false breaks regularly in choppy markets. Wait for the candle to close beyond the line AND for confirmation next day. Some traders require 2-3% beyond the line.
Channel Trade
Ascending channel: support at $72, resistance at $80. Price at $73 near channel support. Enter long at $73, stop at $71 (below channel). Target $79 (near channel resistance). Risk: $2, Reward: $6. R:R = 3:1. Wait for the next support bounce to re-enter.
Key Takeaways
Try This
Find a stock in a visible channel (ascending, descending, or horizontal). Draw the channel lines and identify where price is now. Is it near support (potential buy) or resistance (potential sell)? Calculate the measured move if it breaks out.
