DonutSMP AH Sniper Guide — Print Coins With Argon Addon (2026)
Set up a DonutSMP AH sniper that prints coins overnight. Recommended filters, profit margins, and the exact Argon Addon config that's still pulling 5-10× returns in 2026.
The DonutSMP auction house is the highest-EV money loop on the server. Manual flipping pulls 50-100k coins per hour if you're fast. An AH sniper running through Argon Addon pulls 500k-2M overnight while you sleep.
This guide is the exact config we still use on a real DonutSMP account in May 2026. Numbers are real, settings are copy-pasteable.
How the AH Sniper actually works
Argon's AH Sniper module sits on the network thread (not the render thread) and reads packets the moment they hit your client. When a new auction listing packet arrives, the module:
- Parses the item type, enchants, and price
- Compares against your watchlist filter
- If profitable, fires a buy packet immediately
The entire loop is sub-110ms in v3.2.0. For comparison, a human clicking "buy" after seeing a listing takes 600-1200ms minimum. Most of the best flips are gone in 300ms. So you can see why this matters.
Setup — step by step
1. Toggle the module
Press Right Shift → Misc → AH Sniper → toggle on. Don't configure anything else yet — we're going to set the filters next.
2. Build your watchlist
Click the gear next to AH Sniper. The Watchlist panel opens. Here's the starter list that's still working in May 2026:
- ·
netherite_block— max bid22,000 - ·
elytra (unbreaking III, mending)— max bid180,000 - ·
totem_of_undying(stack) — max bid9,500per - ·
shulker_box (any colour)— max bid14,000 - ·
diamond_block— max bid6,800 - ·
ancient_debris— max bid2,400
These are fire-sale prices — items that sell back at 25-50% profit if you list them yourself afterwards. Adjust ±10% based on current Donut market.
3. Set the profit floor
Min Profit Margin → 25%. Anything under 25% isn't worth inventory slots after listing fees and sell-through delay.
4. Set the cooldown
Buy Cooldown → 120ms. Lower than this and you'll occasionally double-buy your own listing. Higher and you miss the contested flips.
5. Anti-disconnect
Toggle on TpaDisconnect with the danger-list set to known PvPers on your server. AH-AFK means you're a sitting target. TpaDisconnect logs you out the instant a flagged player sends a /tpa request.
Realistic results
An 8-hour overnight run with the watchlist above pulls 500k-2M Donut coins depending on auction volume that day. Weekend overnight runs hit the upper end (more players listing under-priced gear before logging off). Weekday mid-day runs hit the lower end.
Your inventory will be full of bought items — you list them back at fair market price the next day. The sniper does the buying; you do the selling.
Three things experienced flippers do
Filter by enchant combo, not item type
An elytra with just Unbreaking III sells for 80k. With Unbreaking III + Mending it sells for 180k. Filter by combo, not by base item, and your snipe-to-flip ratio doubles.
Stop running during patch nights
DonutSMP pushes anti-cheat updates Wednesday and Saturday evenings UTC. Don't AH-sniper through those windows — false-positives spike. Pause the module from Tuesday 23:00 to Wednesday 03:00 UTC.
Sell back during peak hours
List your bought stock at 16:00-22:00 UTC. That's peak EU/US overlap. Listings move in minutes vs. hours at off-peak.
Why Argon's AH Sniper specifically
Other Meteor Client addons ship AH snipers. Most of them are 300-500ms latency because they read at the render thread, not the network thread. That's enough delay to miss every contested flip. The math is brutal: at 500ms latency you get the leftovers. At 110ms you compete with the top 5% of flippers — and beat them, because most of them are humans.
