⋅ Crypto trade 24 hours a day, so there is no real gap.
But the gap is a price area actually where nobody or very few people trade.
This script marks all those areas on your chart.
You'd better use the daily chart and change the marked candle color same as your chart background color, then you'll see the magic.
You might be able to use whatever technique it is to create a modified volume profile indicator.
