Alerts feel delayed¶

When Trade Ideas alerts “feel delayed,” it’s usually not a data lag problem. It’s a definition + workflow problem:

• your lane is too broad, so the alert fires after the move is already obvious
• your setup definition is vague (“movement happened”) instead of specific (“setup is forming”)
• your alert volume is too high, so you only notice the alert after it’s buried

This page is a fast diagnostic flow to get alerts back to reviewable + actionable.

Quick reality check (30 seconds)¶

1) Is the market open / is your universe correct?¶

• If you’re testing during premarket or after-hours, check session settings.
• Make sure you aren’t scanning a dead symbol list.

2) Are you expecting Trade Ideas to be a “signal”?¶

Trade Ideas is best when you treat alerts like review prompts, not perfect entries. Your edge is usually:

lane → rank → alert → review → execute

If you expect “alert = buy now,” most alerts will feel late.

The 80/20 causes (in order)¶

Cause #1 — Your alert describes movement, not a setup¶

If your alert is basically: - “% move is happening” - “new high” - “volume spike”

…it will fire after the thing is already visible.

Fix: Add at least one setup gate so it triggers earlier in the lifecycle: - position in range (near HOD/LOD, near break level) - time-of-day window - relative volume threshold (in-play filter) - liquidity floor (so you’re not reacting to junk)

Cause #2 — Your lane is too broad (noise hides the good alerts)¶

When your lane is broad, you get: - too many alerts - too many “meh” tickers - delayed attention (not delayed data)

Fix: Tighten the lane first: - add a dollar-volume floor - add average volume floor - use relative volume as a gate - constrain price band to what you actually trade

Cause #3 — Time-of-day mismatch¶

Some setups behave in specific windows. If your alert runs all day, you’ll get: - early noise you ignore - late signals you notice

Fix: Add time windows. Related: - Time of day filter

Cause #4 — You’re validating in the wrong window¶

A common pattern is: - alert fires - you look at a chart/layout that isn’t built for fast validation - by the time you decide, it’s “late”

Fix: Your review station should be ready: - Top List for triage - Chart for context - Alert Window for setup history

Practical troubleshooting flow (do this exactly)¶

Step 1 — Reduce to one alert window¶

Disable everything else. You want to debug one thing at a time.

Step 2 — Confirm it fires at all¶

If it doesn’t fire, you filtered to zero or the condition is too rare. Related: - No alerts

Step 3 — Remove one constraint at a time¶

If it fires late: - remove one condition - observe how the timing changes - add it back only if it improves signal quality

Step 4 — Add one “earlier” condition¶

Pick one: - pre-break trigger (e.g., approaching level) - in-play gate (RVOL) - time-of-day

Step 5 — Add one “quality” condition¶

Pick one: - liquidity floor - universe/symbol list quality

Goal: fewer, earlier, higher-quality alerts.

If you still suspect true latency¶

Actual latency is rare, but if you want to rule it out:

• compare the alert timestamp vs the chart timestamp for the same event
• test on a highly liquid name (SPY / AAPL) where prints are constant
• verify your connection stability

If it’s truly a platform latency issue, it will show up even on ultra-liquid names.
