Recently, I've noticed that many new traders are asking about Bollinger Bands, also known as Bollinger Bands. Actually, what is Bollinger, and why is it so widely used? I'll explain to you in the simplest way possible.

This tool was developed by John Bollinger in the 1980s, and it’s simply three lines drawn on a price chart. The middle line is a 20-period simple moving average, the upper band is the moving average plus two standard deviations, and the lower band is the moving average minus two standard deviations. The interesting part is that these bands are not rigid; they flexibly expand during strong market volatility and contract when the market is quiet.

I often use Bollinger Bands to gauge market sentiment. When the price touches the lower band, it often signals that the asset may be oversold, presenting a potential buying opportunity. Conversely, when the price moves above the upper band, it may be overbought, suggesting it might be time to consider selling. What about the distance between the two bands? If they spread apart, the market is highly volatile; if they squeeze together, the market is calm and a major turning point could be near.

But here’s an important point that many overlook: Bollinger Bands should not be used alone. They only show you volatility, not the direction of the trend. I always combine them with RSI or MACD to confirm signals before entering a trade. What is Bollinger without support from other indicators? Just a part of the puzzle.

In reality, no tool is perfect. The more indicators you use to verify your analysis, the higher your chances of making smart trades. I recommend trying different combinations to see which ones suit your trading style best. In upcoming articles, I will delve deeper into other indicators and how they complement each other to form a powerful strategy. Don’t rush; learn step by step, test on a demo account first, then apply to real trading. Wishing you successful trading!
