We always acquire prices directly from OTAs where possible. In the instances where we can’t access those prices we take the price from a secondary price source. In most instances the secondary source is a metasearch website.
If a disparity has been acquired from meta, you’ll see the name of that meta site in the disparity overview panel in your Parity Monitoring dashboard. You can’t currently link straight through from the meta name to the relevant website but if that would be a helpful feature please let us know by requesting it on our feature request board.
