Support and Resistance: The Foundation of Technical Analysis

Support and resistance are the two most important concepts in technical analysis. If you learn nothing else about trading, learn these. They tell you where price is likely to bounce, reverse, or break through — and that information is the basis of almost every trading strategy.

What Is Support?

Support is a price level where buying pressure is strong enough to prevent the price from falling further. Think of it as a floor. When price approaches a support level, buyers step in because they consider it a good value. The more times price bounces off a support level, the stronger it becomes.

What Is Resistance?

Resistance is a price level where selling pressure is strong enough to prevent the price from rising further. Think of it as a ceiling. When price approaches resistance, sellers take profits or open short positions, pushing price back down.

How to Identify Support and Resistance

1. Historical price levels: Look at where price has bounced or reversed in the past. Those levels tend to be respected again.
2. Round numbers: Psychological levels like $50,000, $100,000 for Bitcoin. Humans place orders at round numbers.
3. Previous highs and lows: The high of the last swing becomes resistance. The low becomes support.
4. Moving averages: The 50-day and 200-day moving averages often act as dynamic support/resistance.
5. Volume profile: Price levels where lots of trading has occurred act as support/resistance.

Key Principles

• Role reversal: When support breaks, it becomes resistance. When resistance breaks, it becomes support. This is one of the most reliable patterns in trading.
• The more touches, the stronger: A support level tested 5 times is stronger than one tested once.
• Breakouts: When price finally breaks through a strong support or resistance level, the move is often significant.
• False breakouts: Sometimes price briefly breaks a level then reverses. Wait for confirmation (close above/below) before trading.

Trading with Support and Resistance

• Buy near support with a stop-loss below it
• Sell near resistance with a stop-loss above it
• Trade breakouts when price closes above resistance (buy) or below support (sell)
• Always use stop-losses — support and resistance can fail

Practice Exercise

Open the Bitcoin daily chart on TradingView. Draw horizontal lines at the last 5 major swing highs and lows. Watch how price reacts when it approaches these levels. This exercise alone will teach you more than most trading courses. Apply this to your trades on Mal.io.
