How to Set Up Custom Trade Alerts on 0xInsider

Most traders miss the trades that matter most to them. A $50K geopolitical bet from a brand-new wallet hits the feed at 3 AM. A crypto whale quietly builds a position while you are watching the wrong market. By the time you check the terminal, the price has already moved.

Custom trade alerts fix this problem. Instead of monitoring the full whale trade feed — which processes hundreds of trades per day across every category — you define exactly what you care about. Category, minimum trade size, wallet type. When a trade matches your criteria, you get notified immediately. No refreshing. No scanning. No missed opportunities.

This is particularly valuable if you specialize. A trader focused on geopolitical markets has no use for NBA trade alerts. Someone tracking crypto whales does not need to see every $3K sports bet. Alerts let you filter the noise at the source and only surface the signals relevant to your strategy.

Each alert supports three filter types that you can combine in any way. The more specific your filters, the fewer — but more relevant — notifications you receive.

Category filters let you target specific market types. You can select one or multiple categories: Politics, Crypto, Geopolitics, NBA, NFL, Soccer, Tennis, Earnings, Economics, Stocks, Science & Tech, Pop Culture, and more. Leave the category filter empty to match trades across all categories.

Minimum trade size sets a USD floor. If you only care about high-conviction moves, set this to $10K, $25K, or $50K. Trades below your threshold are silently ignored. This is the single most effective filter for cutting noise — the difference between a $3K position and a $50K position is the difference between casual betting and serious conviction.

The new wallets filter is a boolean toggle. When enabled, your alert only fires for trades from proxy wallets that have never appeared on the platform before. New wallets are interesting because they often represent fresh capital entering the market — sometimes from informed actors who create new wallets specifically to avoid being tracked. This filter is particularly useful for spotting unusual activity in niche markets.

Open the terminal at 0xinsider.com/terminal. This is the live whale trade feed where every large position is displayed in real time.

Use the filter bar at the top to set the conditions you want to monitor. Click a category chip to filter by market type — for example, select Geopolitics to see only geopolitical trades. Use the size filter to set a minimum trade value in USD. Toggle the new wallets filter if you only want trades from first-time wallets.

The terminal updates in real time as you adjust filters. Take a moment to confirm the feed shows the kind of trades you actually want alerts for. If the filtered feed is too noisy, tighten your criteria. If nothing shows up, loosen them. The goal is a steady stream of relevant trades — not a firehose and not a ghost town.

Once your filters are dialed in, look for the Save Alert button in the filter bar. It appears automatically when you have at least one active filter. Click it to open the alert creation popover.

The popover shows your selected conditions as chips — a visual summary of exactly what this alert will monitor. Give your alert a descriptive name. The system auto-generates one based on your filters (something like "Geopolitics, > $10K, new wallets"), but you can customize it to anything that makes sense to you.

Toggle email notifications on or off. When email is enabled, you receive an email every time a matching trade is detected — with the market name, trade size, and a direct link to the terminal. When email is off, notifications still appear in-app but do not hit your inbox. You can change this setting later without recreating the alert.

Click Save. Your alert is now active and will start matching against every new whale trade that enters the system.

Visit your account page at 0xinsider.com/account and scroll to the Alerts section. Here you see all your active alerts with their conditions, email toggle, and enabled status.

Each alert runs independently — if a single trade matches multiple alerts, you get a notification for each one.

To modify an alert, you can toggle it on or off (pausing without deleting), enable or disable email delivery, or delete it entirely to free up a slot. If you want to change the filter conditions themselves, delete the alert and create a new one from the terminal with your updated filters.

When a new whale trade is inserted into the system — whether from the Polymarket WebSocket feed, the Kalshi WebSocket, or the REST API poller — the alert matcher runs automatically. It checks every active alert against the incoming trade.

Category matching is case-insensitive. If your alert targets "Crypto" and a trade comes in for a market categorized as "crypto," it matches. Size matching uses the trade's notional value (shares multiplied by price), not the raw share count. A 10,000-share position at $0.50 per share equals $5,000 notional — that is what gets compared against your minimum size threshold.

The new wallet check looks at whether the trade's proxy wallet address has been seen before in the system. Polymarket uses proxy wallets for each user, and first-time appearances can indicate new participants entering the market.

Matching runs within seconds of trade insertion. There is no polling delay or batch window. If a trade matches your alert at 2:47 AM, you have the notification by 2:47 AM.

Every matching trade creates an in-app notification. These are visible in your notification panel and persist for 90 days. The unread count updates in real time via server-sent events — you do not need to refresh the page to see new notifications arrive.

Email notifications, when enabled, include a summary of the matching trade: the market title, trade size in USD, whether it was a buy or sell, and a direct link to view it in the terminal. Emails are sent individually per alert, so if two of your alerts match the same trade, you receive two separate emails — each labeled with the alert name that triggered it.

The system is designed to be fault-tolerant. If email delivery fails for any reason, the in-app notification is still created. You never lose a notification because of an email issue.

A geopolitics specialist might create an alert with the Geopolitics category, a $10K minimum, and new wallets enabled. This surfaces only high-conviction geopolitical bets from fresh accounts — exactly the kind of unusual activity that often precedes major market moves.

A crypto trader could set up a Crypto category alert with a $25K minimum and no wallet filter. This catches every significant crypto prediction market position without the noise of smaller trades. When a whale drops $100K on a Bitcoin prediction, you know about it immediately.

A generalist who wants to track unusual activity across all markets might skip the category filter entirely, set a $50K minimum, and enable new wallets. This is a broad net for high-conviction trades from new actors — regardless of category.

Remember that you have 3 alert slots. A common setup is one narrow alert for your primary market (tight category + moderate size), one broad alert for discovery (no category + very high size), and one experimental alert that you rotate based on current events.

Start with a higher minimum size than you think you need. A $5K minimum on a popular category like Politics will generate dozens of notifications per day. A $25K minimum surfaces only the trades worth paying attention to. You can always lower it later if you are not getting enough signal.

Use descriptive alert names. "My alert" tells you nothing when you receive an email at midnight. "Geopolitics > $10K new wallets" tells you exactly why you are being notified and helps you decide whether to act immediately or check in the morning.

Review your alert performance weekly. If an alert consistently fires for trades you ignore, it is too broad — tighten the filters or delete it and reclaim the slot. If an alert never fires, it may be too narrow. The best alerts fire a few times per day with trades you genuinely want to see.

Combine alerts with the terminal's other features. When you receive a notification for a large trade, open the trader's profile to check their grade, win rate, and track record. A $50K bet from an S-grade trader with a 68% win rate carries far more weight than the same bet from an ungraded wallet with no history. The alert gets your attention; the analytics inform your decision.
