Why Timeframes Sometimes Show the Same Values

At certain times, multiple timeframes start new candles at the exact same moment. When this happens, they can display very similar or even identical values, especially right at the open of a new bar.

Example:
It's 10:00 PM. At this time:

• A new 4-hour (H4) candle begins (since H4 candles open every 4 hours — 10:00 , 14:00 , 18:00, etc.)

• A new 1-hour (H1) candle also begins

• A new 30-minute (M30) candle starts as well

All of these timeframes are now at the very beginning of a new candle. Because no significant price movement has occurred yet, the opening price and the current price are still the same across all these timeframes.

As a result, the percentage change — if calculated at this moment — will be identical or very close to zero across all of them.

Why This Happens:
Timeframes are built in a nested structure. Smaller timeframes are subdivisions of larger ones (for example, two M30 candles make up one H1 candle, and four H1 candles form one H4 candle). Due to this, their bars will often open at the same time, particularly on the hour or at common intervals.

This could give the illusion of alignment or confluence between timeframes, when in fact, no meaningful price action has taken place yet. This can lead to misleading signals or premature entries.
