How settings work

Where settings live, when a change takes effect, and which values get corrected on save.

Settings live in Reddit’s app-settings UI. Open your subreddit’s apps page, find Trade Post, press settings. They are per subreddit and moderators only.

Group	Decides
Listing format	How titles are built, and what a lister may say
Photo requirements	When photos are mandatory
Trades	How long silence is tolerated, and what is recorded
Inventory	Who sees whose items, and when items are deleted
Reputation	What a completed trade does to user flair

When a change takes effect

Wait about a minute before testing. A trader who already has the hub open keeps the old rules until they close and reopen it.

Two waits:

• Subreddit-wide, about a minute. In that window a trader can see the old rules in the composer while the server judges by the new ones. Reloading does not help; the wait is shared across the subreddit.
• Per session, until the hub is reopened. A trader with the hub already open keeps the rules they opened it with.

Values corrected on save

Eight fields refuse a bad value. The other sixteen accept it and move it into range without an error, and the settings screen keeps showing what you typed.

Setting	Typed	Applied
Days before silence counts as ghosting	60	20
Max items per listing	500	100
Wants shown in the title	50	20
Photos per item	20	8
Delete items nobody has touched in	30	90
Delete items nobody has touched in	1095	730
Max items one trader may hold	500	200

Fields where 0 is not zero

Setting	0 means
Max items one trader may hold	No limit below the 200 ceiling
Delete items nobody has touched in	Keep forever
Delete traded items after	Follow the setting above

Keeping traded items forever requires both item windows set to 0. Setting only the traded window leaves traded items on the idle window, which defaults to 180 days.

Fields validated on save

Region tag format, “Have” tag, “Want” tag, Looking-for options, Condition options, Flair for a trader with no count yet, Your subreddit’s trade bot, The comment your bot expects.

The refusal names the problem. A region format with no tokens returns “Include at least one token, e.g. <COUNTRY>, <STATE>…”

A blank region format blocks the save. A blank bot name saves and silently disarms “Keep our existing bot”: no flair, no comment, no error, and the confirm button never appears.

Not configurable

• A deleted Reddit account’s items are always removed.
• An item stuck on a trade that no longer exists is always freed.
• A stalled trade always closes at its deadline, releases its goods, and posts the notice. Only whether it counts against anyone is configurable.
• Deleting a listing post always erases its record, its offers and its trades.
