Can't show or keep week view on Exchange page

Describe the bug

I added a 1w bucket to the api.bts.mobi API node, but the reference wallet does not use it.

To Reproduce
Steps to reproduce the behavior:

1. Go to https://develop.bitshares.org/#/market/BTS_XBTSX.USDT
2. Choose the api.bts.mobi API node
3. Fresh page, choose "1 hour" in the chart, then choose "7 days" in the chart
4. See error: the chart shows "D" with data starting from 600 days ago
5. choose "7 days" again, the chart shows "7D", however, the range of data does change. By checking API calls with web developer tools, the bucket used in requests are still 86400.
6. go to another market
7. the chart shows "D" again
