Candlestick charts originated in 18th-century Japan and remain the dominant way to visualize price action today. Each candle represents a specific time period — one minute, one hour, one day — and tells you four critical pieces of information: the open, high, low, and close.

A bullish candle (usually green or white) closes above its open. A bearish candle (usually red or black) closes below its open. The rectangular body shows the range between open and close. The thin lines above and below the body — called wicks or shadows — show the high and low reached during that period.

Price patterns are recurring structures that hint at future direction. The engulfing pattern is one of the most reliable reversal signals. A bullish engulfing occurs when a small red candle is completely consumed by a larger green candle. It suggests buyers have overwhelmed sellers.

The doji is a candle with almost no body, where open and close are nearly identical. It signals indecision — a tug-of-war where neither side won. When a doji appears after a strong trend, it often foreshadows a reversal or consolidation. The hammer is a bullish reversal pattern with a small body at the top and a long lower wick. It shows that sellers pushed price down, but buyers recovered sharply before the close.

Support is a price level where buying interest is strong enough to overcome selling pressure. It acts like a floor. Resistance is the opposite: a ceiling where selling pressure overwhelms buyers. These levels are not magical lines — they are zones where large numbers of orders historically cluster.

The more times a level is tested and holds, the more significant it becomes. However, once a level is broken decisively, it often flips roles. Former support becomes resistance, and former resistance becomes support. This phenomenon, known as polarity change, is one of the most reliable concepts in technical analysis.

A trendline is a straight line connecting two or more swing lows in an uptrend, or swing highs in a downtrend. It visualizes the trajectory of price and acts as dynamic support or resistance. The more touch points a trendline accumulates, the more valid it becomes.

Parallel trendlines form a channel. In an ascending channel, price oscillates between an upper resistance line and a lower support line. Traders often buy near the lower boundary and sell near the upper boundary — a strategy called range trading within a trend. A breakout beyond the channel can signal acceleration or reversal, depending on volume and context.

No single timeframe tells the complete story. Professional traders analyze at least three: a higher timeframe for context, a trading timeframe for entries, and a lower timeframe for precision. For example, you might use the daily chart to identify the trend, the 1-hour chart to find a pullback entry, and the 15-minute chart to time your exact stop placement.

The golden rule is to align your trade with the higher timeframe trend. Buying pullbacks in an uptrend on the daily chart has a higher probability than counter-trend scalps on the 5-minute chart. Timeframe alignment filters out low-quality setups and keeps you on the right side of the market.

A consistent routine prevents emotional decision-making. Start with the daily chart every morning: mark key support and resistance zones, note any obvious trends or ranges, and identify the nearest higher-timeframe structure. Then drop to your trading timeframe and wait for price to reach one of your pre-marked zones.

Before entering, confirm the setup with at least one confluence factor: a candlestick pattern, a moving average alignment, or a divergence signal. Set your stop loss beyond the nearest structure and calculate your position size so that the risk is 1-2% of your account. Record the trade in your journal, including your reasoning and emotional state.
