If you're a developer and want to make a custom stock rule without customer support,
here are the functions you can use. Rules are evaluated using a strict subset of javascript.

No more than - Never advertise more than this much inventory as available. Great to fight competitor's repricing tools or to stay under eBay's item limit. Note: This will toggle between being a unit off to ensure stock sync sees a valid change in stock to push regularly.

no_more_than(free, 10)

No less than - Never advertise LESS than this much inventory as available. Directly permit overselling. Note: This will toggle between being a unit off to ensure stock sync sees a valid change in stock to push regularly.

Snapping - Starting with the "start" value only provide rough figures for actual availability. e.g. 50, 100, 200, 400, 1000, 2000, 10000, 20000.
