How to set up custom trade alerts on 0xinsider

The trade you care about rarely lands while you are watching. A $50K geopolitical bet from a brand-new wallet lands in the live feed at 3am, and by the time you look, the price has moved.

The full large-trade feed carries hundreds of trades a day across every category. An alert narrows it to what you trade: a category, a minimum size, a wallet type. A trader focused on geopolitical markets has no use for NBA trades, and someone tracking large crypto positions does not need every $10K tennis bet.

Each alert combines up to 4 conditions: category, minimum size, grade, and new wallets. The more specific they are, the fewer notifications you get and the more relevant each one is. Pro holds 50 alerts and can set all 4. An account without Pro holds 1 alert: a category alert from the live feed, or a game alert from a game page.

Category: pick one or several, such as Geopolitics, Politics, Crypto, Soccer, or Tennis. Leave it empty to match every category.

Minimum trade size: a USD floor, from >$10K up to >$500K. Trades below it are ignored.

Grade: the lowest grade you want to hear from. If you pick several grades in the live feed, the alert saves the lowest of them as its floor, so picking S and B also matches A.

New wallets: the alert fires only for wallets whose trading history 0xinsider has not synced yet. That marks a wallet 0xinsider has not profiled, not a wallet that is new to Polymarket. The condition works best in niche markets.

Open the live feed of every large trade at 0xinsider.com/trades.

In the filter bar at the top, pick a category (Geopolitics, for example) and set Size and Grade. Open the New wallets view if you want only wallets 0xinsider has not profiled yet.

The feed updates as you adjust. Check that it shows the trades you want alerts for. If it is too noisy, tighten the filters. If nothing shows up, loosen them.

The Save Alert button appears in the filter bar once at least one filter is active. Click it to open the alert popover, which shows your conditions as chips.

The name fills in from your conditions, for example "Geopolitics, > $10K, new wallets", and you can change it. An alert saved with the name cleared is called Custom alert.

Email starts on, and you can turn it off. With email on, matches go out in a 15-minute digest when that window holds a match of $25,000 or more, 3 or more matches, or a trade from a wallet you follow. A quieter window rolls into a daily email. With email off, notifications still appear in the app. You can change this later without recreating the alert.

Click Save. The alert is active and matches against every new large trade that enters the system.

Sign in, open Account from the menu, and go to Trade alerts. It lists every alert with its conditions, email toggle and enabled status.

Each alert runs independently, so one trade that matches several alerts produces a notification for each.

You can turn an alert off to pause it without deleting it, turn its email on or off, or delete it to free a slot. To change the filter conditions, delete the alert and create a new one from the live feed.

The matcher checks each new large trade against every active alert as the trade is stored.

Category matching is case-insensitive: an alert for "Crypto" matches a market categorized as "crypto". Size matching uses notional value, shares multiplied by price, not the share count. A 10,000-share position at 50¢ is $5,000 notional, and that is the figure compared with your minimum.

The new-wallet condition asks whether 0xinsider has synced the wallet's trading history yet. A wallet it has not profiled counts as new, even if that wallet has traded on Polymarket before.

Matching runs within seconds of insertion. A trade that matches at 2:47am produces the in-app notification at 2:47am. The email follows in that window's digest, or in the daily email when the window is quiet.

Every matching trade creates an in-app notification. Notifications stay in your panel for 90 days, and the unread count updates in real time over server-sent events, so you do not need to refresh the page.

An email, when enabled, carries the market title, the trade size in USD, whether it was a buy or a sell, and a direct link to the trade in the live feed. Emails are bundled per user, one digest per 15-minute window: if two of your alerts match the same trade, the digest shows both alert sections in one message.

If email delivery fails, the in-app notification is still created.

Custom alerts match trades. To hear when pUSD arrives in a wallet you follow, before it trades, Pro has funding alerts on covered profiles; the guide at 0xinsider.com/learn/how-to-track-polymarket-wallet-funding covers them.

A geopolitics specialist: the Geopolitics category, a $10K minimum, new wallets on. Geopolitics carried 91 large trades in the 30 days to September 20, 2026, about 3 a day before the wallet filter, so the category does the work and the size floor does none.

A crypto trader: the Crypto category, a $25K minimum, no wallet filter. Crypto ran 110 large trades in that window, 30 of them at $25K or more, about one a day.

A generalist: no category, a $50K minimum, new wallets on. That floor alone is 1,268 trades in the window, about 42 a day, so the wallet toggle is what keeps it readable.

A starting Pro setup can use 3: a narrow alert for your primary market, a broad alert with a high size floor for discovery, and one you rotate with current events.

Set the minimum where it changes something. Over the 30 days to September 20, 2026 the feed recorded 13,796 large Polymarket trades, about 460 a day, and its own floor already sits near $10,000: the smallest was $1,019.75, and only 2 of the 13,796 came in under $10K. A floor below $10,000 changes almost nothing.

$25K is the first setting that changes your inbox: 3,611 trades in that window, about 120 a day. $50K gives 42 a day and $100K gives 15. The chart at the top of this guide shows each floor.

Category narrows faster than size. In the same window Soccer ran about 120 large trades a day, Tennis 96, Esports 90, Baseball 66, Politics 41, NFL 14 and Geopolitics 3. Pairing a category with $25K is what turns a feed into an alert: Politics at $25K is about 11 a day, Geopolitics about one every other day.

Name alerts for what they match. "My alert" tells you nothing in an email at midnight. "Geopolitics > $10K new wallets" tells you why you were notified and whether it can wait until morning.

Review alerts weekly. One that keeps firing on trades you ignore is too broad: tighten it, or delete it and reclaim the slot. One that never fires may be too narrow. A good alert fires a few times a day with trades you want to see.

When a notification arrives, open the trader's profile and check the grade, the win rate and the track record. A $50K bet from an S-grade trader with a 68% win rate carries more weight than the same bet from an ungraded wallet with no history.
