Hello,
Your screenshot shows the plugin working as expected.
If it is a new setup, it is expected that the orderbook and price charts are empty.
As you and others enter orders, the orderbooks will fill.
When some of these orders match, there will be candlesticks in the chart. First the smaller timeframes will fill, then as time passes, the longer timeframes will also show candlesticks.
Please let me know if you have any more questions.
kind regards
