Speaking of charts ....
Your chart reminds me more of a chart from traditional financial markets. There are a lot of "empty places" on it. But after all, the cryptocurrency market, unlike others, works round the clock and seven days a week. Why it happens?

Those empty spaces, which you've noticed on our charts, are connected with the history completed orders. If there were such a period, when there was no or very low activity, then a blank space appeared.
