Earlier I saw that many people are still confused about the BU-BB term on the chart, even though it’s very important if you are serious about technical analysis and supply demand strategy. So I want to explain the meaning of BU and this concept in a more practical way.

So here’s the thing, BU-BB is an abbreviation for Buy-Up to Break Base. It means you buy from the demand zone or accumulation area, then hold until the price breaks through the established support level. If you understand the meaning of BU in this context, it means you already know the right timing for entry. The price rises from a strong demand area, and the momentum continues until it breaks a certain level. That’s a good time to follow the momentum.

Then there’s BB-OB, which stands for Break Base to Order Block. This is the next phase after BU-BB. So after the price successfully breaks the support, it will move toward the nearest order block, whether it’s a supply area or an even stronger demand area. You can follow this movement for a more targeted trade execution.

To summarize, the meaning of BU in trading is about timing and momentum. BU-BB is the buying phase with upward momentum until the break, while BB-OB is the follow-up move toward the next target. If you can read these two phases correctly, your entry and exit points will be much more solid on the chart.

My tip is, don’t just memorize the terms, but understand the price dynamics behind them. Observe how supply and demand work at each level, and you will start to see these patterns repeat across different timeframes. That’s what makes technical analysis more effective.
