Trend Lines & Channels

The market spends most of its time trending — either up, down, or sideways. Trend lines and channels let you visualize the direction and boundaries of a move. More importantly, they tell you when a trend might be ending.

The Three Market States

Price is always in one of three states. Understanding which one you're in changes everything about how you should trade:

Uptrend: Higher highs and higher lows. Each peak and each trough is higher than the last. Buyers are in control.
Downtrend: Lower highs and lower lows. Each peak and trough is lower than the last. Sellers are in control.
Sideways / Range: Price bounces between two horizontal levels. Neither side is winning. Often happens after a strong move.

Three Market States

Drawing Trend Lines Correctly

A trend line connects at least two significant price points and projects the direction of the trend. The key word is significant — don't just connect any two candles.

Uptrend Line (Support)

Connect the lows of an uptrend. At least two clear swing lows. The line sits below price and acts as dynamic support — price bounces off it as the trend continues.

Downtrend Line (Resistance)

Connect the highs of a downtrend. At least two clear swing highs. The line sits above price and acts as dynamic resistance.

How to Draw Trend Lines — Uptrend Example

Two Touches = A Line. Three Touches = Significant. Any two points define a line — that's geometry. But when price bounces off a trend line three or more times, you know the market is respecting it. That's when it becomes a genuinely useful level to trade from.

Drawing Valid Trendlines — Minimum 2 Points, 3rd Touch Confirms

Channels

A channel is two parallel trend lines — one connecting the lows, one connecting the highs. Price bounces between them like a ball between two walls. This gives you both entry points (at the lower line) and targets (at the upper line).

Trendline Break & Retest — Entry After Confirmation

Trend Line Breaks — The Most Important Signal

When price breaks through a trend line with conviction, it often signals that the trend is ending or pausing. This is one of the most watched signals in technical analysis.

But not every touch is a break. Price can briefly pierce a trend line and snap back — this is called a "false break" or "fake out." To confirm a break:

Price closes clearly beyond the trend line (not just a wick)
The break happens on higher-than-average volume
Price retests the broken line from the other side and holds

✓ DO

Connect significant swing points
Wait for 3+ touches before trading it
Check volume on the break
Wait for a retest after breakout
Use higher timeframes for context

✗ DON'T

Force a trend line to fit
Trade the first touch
Ignore volume on the break
Chase price after a big breakout
Draw trend lines on 1-minute charts

The Most Common Mistake: Forcing It If you have to tilt the line at a weird angle just to connect two points, it's not a valid trend line. The market draws its own lines — your job is to find them, not invent them.

Key Takeaways

Markets are always in one of three states: uptrend, downtrend, or sideways
Uptrend lines connect the lows. Downtrend lines connect the highs.
Two touches = a line. Three touches = a significant, tradeable level.
Channels give you both entry zones (lower line) and profit targets (upper line)
A trend line break with high volume + retest = strong reversal signal
Never force a trend line — if it doesn't fit naturally, it's not there
