Support and Resistance

5.1 The floor that kept holding

Over three months, Bitcoin had dropped to around $92,000 three separate times, and each time it bounced back up. Mint noticed it immediately.

"It's like there's a floor at $92,000," said Mint.

"Traders call that support," said Hash. "And the ceiling it kept failing to break, around $108,000, is resistance. These two ideas are the foundation of almost everything else in technical analysis."

5.2 What they are

Support is a price area where buying interest has been strong enough to stop a decline. Resistance is a price area where selling interest has been strong enough to stop a rise.

Why do these areas form? Because markets have memory.

At support: traders who missed buying last time see a second chance. Traders who bought there before defend their position. Short sellers take profits there, which means buying.

At resistance: traders who bought at that level earlier and suffered a loss are relieved to sell at breakeven. Traders who sold there before expect it to work again. Buyers hesitate.

Think of a shopkeeper who has noticed that customers buy lots of umbrellas when the price drops to $10, but almost nobody pays more than $20. Without any formal rule, $10 becomes a floor and $20 a ceiling, simply because of how people behave around those prices.

5.3 Zones, not lines

Beginners draw support and resistance as exact lines. Experienced traders treat them as zones.

Bitcoin's three bounces didn't happen at exactly $92,000. The lows were $91,400, $92,300, and $91,800. The support is the zone from about $91,400 to $92,300, not one precise number.

Bounce	Low
First	$92,300
Second	$91,400
Third	$91,800
Support zone	About $91,400 to $92,300

This matters in crypto especially, because liquidation wicks often poke briefly through a level before price recovers (Chapter 3). A trader who treats support as an exact line might see a tiny break and panic. A trader who uses a zone, and waits for candles to close, avoids many false alarms.

5.4 How to find them

Source	Why it matters
Previous highs and lows	Where the market turned before, it often reacts again
Areas with many touches	The more times a level holds, the more traders notice it
Areas of heavy trading volume	Where many traders hold positions, they're likely to react (Chapter 7)
Round numbers	Psychological levels like $100,000 or $3,000 attract orders
All-time highs	A major reference point for the whole market
Moving averages	Dynamic support and resistance (Chapter 8)
Fibonacci levels	Popular retracement levels (Chapter 13)

Round numbers deserve a note in crypto. Levels like $100,000 for Bitcoin generate enormous attention, media coverage, and clustered orders. They often cause hesitation and volatility as price approaches them.

5.5 What makes a level stronger

Not all levels are equal.

More touches: a level tested three or four times is more significant than one tested once. Though, as discussed below, each test can also weaken it.

Higher timeframe: a level visible on the weekly chart outweighs one on the hourly chart.

Strong reactions: a level that caused a sharp, high-volume reversal is more meaningful than one that caused a small pause.

Recency: recent levels tend to matter more than ones from years ago, though major historical highs remain important.

5.6 Role reversal

One of the most useful ideas in technical analysis: when resistance breaks, it often becomes support, and when support breaks, it often becomes resistance.

Imagine Bitcoin finally breaks above $108,000 after failing there for months. Traders who sold at $108,000 might now want to buy back in. Traders who missed the breakout wait for a pullback to $108,000 to buy. So when price returns to that level from above, it often holds as support. This is called a retest.

Stage	Price behaviour	Role of $108,000
Before breakout	Fails to rise above $108,000 several times	Resistance
Breakout	Closes clearly above $108,000 with strong volume	Broken
Retest	Pulls back to $108,000 and bounces	Now support

The same works in reverse. If the $92,000 support breaks, traders who bought there are now losing. When price climbs back to $92,000, many sell to get out at breakeven, turning old support into new resistance.

Chapter 5 · Support, resistance, and role reversal

Price holds a support zone, with wicks piercing it but closes staying above. It then breaks above a resistance zone, returns to retest that level as new support, and continues higher. A separate fakeout shows a wick sweeping beyond a zone before snapping back.

5.7 Breakouts and fakeouts

A breakout is when price moves decisively through support or resistance. A fakeout, or false breakout, is when price briefly moves through a level and then reverses back.

Fakeouts are very common in crypto. Large traders know where stop-losses and liquidations cluster, often just beyond obvious levels. Pushing the price through the level can trigger those orders, providing liquidity, before the price reverses. Traders sometimes call this a liquidity grab or stop hunt.

Ways to reduce the risk of trading fakeouts:

1. Wait for a candle close beyond the level, on your chosen timeframe, not just an intraday spike.
2. Check volume. Genuine breakouts usually have above-average volume.
3. Wait for a retest. Some traders enter only after a successful retest of the broken level, accepting a possibly worse price for more confirmation.
4. Avoid placing stops exactly at obvious levels. Give them room beyond the zone.

5.8 Each test can weaken a level

"If the level held three times, won't it hold again?" Mint asked.

"Sometimes the opposite," said Hash. "Every time price tests support, some of the buyers there get used up. If price keeps returning to the same level, it can mean sellers are persistent, and the buyers are slowly running out. Many strong breakdowns happen after the fourth or fifth test."

This is why technical analysis isn't mechanical. The same observation, many touches, can support opposite conclusions depending on volume, trend, and how the bounces look. If each bounce gets weaker, the level may be close to breaking.

5.9 Trading with support and resistance

Support and resistance give natural reference points for planning trades:

Plan element	Using support and resistance
Entry	Near support in an uptrend, or after a breakout and retest
Stop-loss	Just beyond the support zone, where the idea is clearly wrong
Target	The next resistance zone above
Avoid	Buying right below strong resistance or selling right above strong support

Chapter 16 turns this into a full trading plan with position sizing.

5.10 Try it yourself

On the daily chart of Bitcoin, mark the three most obvious support zones and three resistance zones from the last year. Use zones, not lines. Then switch to the weekly chart and see which of your zones are still visible. Finally, find one example of role reversal, where old resistance became support after a breakout.

Key takeaways from this chapter

1. Support is where buying has stopped declines; resistance is where selling has stopped rises.
2. They form because traders remember past prices and act around them.
3. Treat levels as zones, especially in crypto where wicks often pierce them briefly.
4. Find levels from previous highs and lows, repeated touches, high-volume areas, round numbers, and all-time highs.
5. Broken resistance often becomes support, and broken support often becomes resistance.
6. Fakeouts are common. Wait for closes, check volume, and consider waiting for retests.
7. Repeated tests can weaken a level rather than strengthen it.
