This is the spread of price movement within one period, for example a day or a week, the price is in the range stand until any news appears and as the news comes out the price breaks out of the range up or down.
For example, now the trading diapason for bitcoin is $7800 - 9800.
I also did not hear about
trading diapason before today. can you please explain more about it? I have understood that btc goes down from $9800 and breaks at $7800 and starts to move up. For that, are you said $7800-$9800 is the trading diapason area? and if btc goes down to 6000$. Then what will be the trading diapason? from $6000-$9800 or $6000-8200$ ?
