An overnight flip is an offer you place before logging off and collect when you are back. It suits items that trade too slowly to flip while you watch, but whose margin is wide enough to be worth the wait. Fast items are a poor fit: their margins are thin and get competed away within minutes.

Every row below has a margin after tax of at least 2% of the buy price, a spread that beat tax in at least half of the last 24 hours, and volume too low for the daytime list. Prices that swing too much, or that have not traded in the last 6 hours, are left out, because an unattended offer cannot react.

Set the buy a little under the listed price and the sell a little over, so the offer fills when the market comes to you instead of you chasing it. When you log back in, check whether the price moved while you were away before relisting. The buy limit resets 4 hours after your first purchase, so a long session away can cover two windows.

Buy is the insta-sell price your buy offer fills at; sell is the insta-buy price. Potential / 4h is the margin after tax times what this bankroll can buy in one 4-hour window, capped by the buy limit and by a tenth of the volume that traded in the last 4 hours. It is an estimate, not a promise. Check any item's limit on the buy limits list, or size flips to your own bankroll in the screener.
