Monitor Cold Start: Your First 7 Days with Catalayer Monitor

Why a Plan Matters

New users typically create 1 broad monitor, get flooded with alerts, disable it within a week, and conclude "Monitor doesn't work for me".

The actual pattern that works: start narrow, measure, refine. This guide walks through a proven 7-day cold-start.

Day 1: Define What You Actually Want to Catch

Before creating any monitor, write down in plain language what events you want to be alerted about.

Bad: "News about my stocks" Good: "Supply chain or delivery issues at Tesla that could affect Q2 earnings"

The specificity matters because Monitor is only as good as its rules.

Exercise

List 5-7 specific event types you care about. For each, write what would trigger action on your part.

Examples:

• "FDA approval decisions for biotech names I hold" → buy/sell trigger
• "SEC investigation announcements for portfolio names" → sell trigger
• "Supply chain disruption for semiconductor companies" → buy trigger on adjacents
• "M&A deals in sectors I trade" → arbitrage opportunity

Day 2: Build Your First Monitor (Narrow)

Pick the single most actionable item from Day 1. Create one monitor for it.

Example: FDA decisions for my biotech watchlist

(FDA AND (approval OR approved OR rejected OR CRL)) AND (BIIB OR MRNA OR PFE OR JNJ OR GILD)

Keep the ticker list to names you actually hold or actively trade. Not all biotech names ever — that's too broad.

Set delivery to in-app only for now. Skip Island until rules prove out.

Day 3: Observe, Don't Tune Yet

Let the monitor run 24 hours. Expect 1-5 alerts.

Review each alert and mark mentally:

• Genuinely useful — you'd have acted on it
• False positive — irrelevant despite matching keywords
• Duplicate — same story from multiple sources

Don't modify the rule yet. You need data on how it behaves before adjusting.

Day 4: First Refinement

Based on Day 3 observation:

If too many alerts

Add NOT filters for the common noise patterns. For FDA monitor, common false positives include analyst notes citing FDA decisions — add AND NOT (analyst OR rating OR downgrade OR upgrade).

If too few alerts

Either you correctly narrowed too tight, or your rule has terminology gaps. Check recent news in your target category manually — did any stories exist that your rule should have caught? If yes, which keywords did they use that your rule missed?

If duplicates

Enable monitor dedup (in Monitor settings). This collapses stories from multiple sources about the same event.

Day 5: Add Monitor #2 (Different Event Type)

Now add a second monitor for a different event type. Don't just make Monitor #2 broader — make it different.

If Monitor #1 was FDA biotech, Monitor #2 might be M&A in your sector:

(acquisition OR merger OR buyout OR "tender offer") AND (SEMI OR TSM OR NVDA OR AVGO) AND NOT (rumor OR denied)

This tests whether your process works across categories.

Day 6: Evaluate Against Actual Outcomes

Open each alert from Days 3-5. For each:

1. What was the price action after the alert? (Check 30-min, 2-hour, 1-day moves)
2. Did you act on it? If yes, did it pay off? If no, should you have?
3. Would you want a similar alert next time?

This is the feedback loop that makes Monitor valuable. Over time, you'll discover:

• Which of your monitors generate profitable signals
• Which are entertainment-only (interesting but not actionable)
• Which should be muted (alerts that consistently don't lead to action)

Day 7: Promote to Island + Add 3 More

By now you have 2 monitors generating useful alerts. Two actions today:

Promote to Desktop

In the monitor that produces the highest-signal alerts, enable [Island](/guides/island-desktop-notifications-setup) routing. Now you get native macOS notifications within 60 seconds of fires.

Add 3 More Monitors

With the template you've validated, add 3 more monitors for different event types. Typical set of 5 monitors for a retail trader:

1. Earnings surprises + guidance for specific tickers
2. FDA / regulatory decisions for watchlist
3. M&A in your sector
4. Supply chain disruption (semis, rare earths, etc.)
5. Your specific portfolio tickers + any material keyword

What Good Looks Like (Week 2)

By Day 14:

• 5 active monitors, each generating 2-10 alerts/day
• < 20% false positive rate per monitor
• At least 1-2 alerts/week that led to actions you wouldn't have taken otherwise
• Desktop push on 1-2 highest-signal monitors (Island)

If you're not at this level by Day 14, either:

• Your rules are still too broad (tune further)
• The events you're monitoring don't actually affect your trades (rethink what matters)
• You need broader source coverage (check region filters)

Common Cold-Start Mistakes

Mistake 1: Creating 10 Monitors on Day 1

More monitors = more noise. Create one, validate, then expand.

Mistake 2: Going All-In on Island Immediately

Desktop push on broad rules = notification fatigue. Only route proven high-signal monitors to Island.

Mistake 3: Not Reviewing Alert Quality

Alerts that don't get reviewed get ignored by the system's learning loop. Spend 5 min/day rating alerts during cold start.

Mistake 4: Over-Indexing on Speed

If your trading strategy is multi-day swing or longer, sub-60s alerts are overkill. Optimize for precision, not latency.

Beyond Day 7

Week 2-4: refine rules based on observed patterns. Add or remove NOT filters weekly.

Month 2: let the AI relevance scoring kick in (it takes 50+ user interactions to calibrate per user). Alerts you routinely dismiss get downranked automatically.

Month 3+: Monitor becomes a daily habit. You check it instead of random news sites.

FAQ

A: 1 monitor. Monitor Plus ($19.99/mo) allows 5. All Access allows 20.

A: Going forward only. When you create a rule, it starts matching from that point on. Historical search is a separate workspace feature (News search), not part of Monitor.

A: Not yet. Team sharing is planned but not released.
