Why Might It Be Called "Bubbles"?
Although not officially named so, some traders or platforms might refer to Bollinger Bands as "bubbles" because:

The bands visually surround the price like a bubble.
During low volatility, the bands form a tight "bubble" around price.
Breakouts look like the price "popping out" of a bubble.
Hence, the nickname "пузырьки" (bubbles) could be a colloquial or visual metaphor for Bollinger Bands in Russian-speaking trading communities.

Conclusion
While there is no official technical indicator called "Bubbles", the term likely refers to Bollinger Bands due to their visual appearance and function. This powerful tool helps traders assess volatility, spot potential reversals, and time entries and exits. When combined with other analysis methods, Bollinger Bands remain a cornerstone of modern technical trading.

🔧 Tip: You can find Bollinger Bands on almost every trading platform (TradingView, MetaTrader, ThinkorSwim) by searching "Bollinger Bands" in the indicators list.
