Candlestick charts are a technical analysis tool used to show price movements. To understand and analyze these graphs, there are some basic rules:

Selecting the time interval: It is important to choose the appropriate time interval for the analysis of an asset. Short-term candles such as hourly or daily candles are used for short-term analysis, while weekly or monthly candles are preferred for long-term analysis.

Candle Colors: Green or white candles usually indicate an increase in price, while red or black candles represent a fall in price. Colors may vary from market to market and may not always follow this convention.

Body and shadows: Each candle consists of a body and shadows. The body represents the opening and closing prices, while the shadows indicate the highest and lowest prices within the time range.

Candlestick Patterns: Different candlestick patterns represent bullish or bearish trends. For example, a "doji" pattern suggests indecision in the market, while a "hammer" or "shooting star" could indicate a change in trend.

Combination with indicators: Candlestick charts are often used in conjunction with other technical indicators. Using moving averages, RSI (Relative Strength Index) or other indicators can help better understand price movements.

Trend Identification: Candlestick charts can help identify ascending (bullish), descending (bearish) or sideways trends. This is key to making investment decisions.

Stop Loss and Targets: Candlestick chart analysis is often part of a trading strategy. This strategy may include stop-loss levels and price targets.

Experience and Practice: Experience is essential to interpret candlestick charts effectively. Regularly watching charts and gaining experience in real markets can help develop these skills.
