Trade Ideas Time of Day filter: premarket vs open vs midday (common mistakes)¶
The fastest way to “ruin” a good scanner is letting it run all day. Your lane might be fine, but the session is wrong — so you get noise, chop, and signals you’ll never act on.
This guide explains how to use Time of Day in a way that matches reality.

What “Time of Day” means in Trade Ideas¶
In most Trade Ideas windows, Time of Day is expressed as: minutes after the regular-session open.
That means: - 0 = the open - 30 = 30 minutes after the open - 90 = 1.5 hours after the open
How to choose your session window (practical)¶
Choose a window that matches your routine and attention span.
Common “mentor-style” ranges: - Open focus: 0–60 (fast, noisy, lots of movement) - Let it settle: 15–120 (filters out the first spike) - Morning only: 30–180 (good for structured review + alerts)
If you don’t trade midday, don’t scan midday.
Premarket vs regular hours¶
Premarket scanning is usually better handled as a Top List workflow: you’re building a candidates list, not triggering alerts every second.

The 3 common mistakes¶
1) Forgetting Time of Day exists¶
This is the #1 reason “Trade Ideas is too noisy”.
If you’re getting spammed, tighten time before you touch anything else.
2) Using a time window you can’t actually act on¶
If you can only trade 9:35–11:00, don’t let alerts fire at 2:00 PM.
3) Trying to solve liquidity problems with Time of Day¶
Time helps, but liquidity is a separate knob. If everything is thin, fix the lane first: - Liquidity filters: Dollar Volume vs ADV vs Volume Today
Regime-specific presets (starting points)¶
| Regime | Suggested Time of Day | Notes |
|---|---|---|
| High momentum open | 0–90 | Keep strict liquidity filters; expect noise |
| Typical morning trend | 15–150 | Good balance of speed + quality |
| Choppy / low conviction days | 30–120 | Reduce weak open noise |
| Midday-only workflows | 120–300 | Use only if your strategy is built for it |
Treat these as defaults, then tune with your own logs.
Recommended pairing: Time of Day + liquidity¶
Time is a noise gate. Liquidity is a quality gate.
If you only set time, you can still get junk. If you only set liquidity, you can still get alerts when you’re not watching.
Use both.
FAQ¶
What’s the best Time of Day range in Trade Ideas?¶
There isn’t one. Pick the range that matches when you’re actually watching and acting. Many traders start with 15–120 or 30–180 and adjust from there.
Why do my alerts look great at the open but awful later?¶
Because the market regime changes intraday. Narrow your Time of Day window and/or build separate windows per session.
