对于这个膨胀的查询，我应该添加什么SQL索引?

I'm wondering if indexes will speed this query up. It takes 9 seconds last time I checked. The traffic table has about 300k rows, listings and users 5k rows. I'm open to ridicule/humiliation too, if this is just a crappy query altogether. I wrote it long ago.I'm wondering if indexes will speed this query
