Best Trade Ideas filters for momentum day trading (what matters)¶

Momentum trading doesn’t fail because you didn’t find “the perfect indicator.” It fails because you traded the wrong candidates and then interfered with your own plan.

This guide is the momentum lane that avoids the two biggest traps: - overfitting (stacking filters until it only works in hindsight) - low-float cheap chaos (where "momentum" often means random spikes)

The story (what actually changed results)¶

The early mistake is almost always too many filters. People build a monster scan, then wonder why: - nothing qualifies in real-time, or - everything qualifies and it’s unusable.

The upgrade isn’t more complexity. It’s a lane with a few strong constraints — then executing without taking profits early or cancelling trades out of fear.

The momentum lane (defaults that work in the real world)¶

1) Liquidity (non-negotiable)¶

Liquidity is the difference between a tradable trend and a trap.

Start with: - spread you can tolerate - solid average volume - strong dollar volume (so you’re not trading ghosts)

Read + config: - Liquidity filters

Liquidity filters config — Liquidity is your first filter. If exits are messy, the whole strategy breaks.

2) Price floor (keep it clean)¶

A practical default that removes a lot of junk: - nothing under $15

This isn’t a moral rule — it’s a “reduce edge-case behavior” rule.

3) Float awareness (avoid chaos)¶

If your goal is repeatable momentum behavior, the biggest noise filter is: - avoid low-float cheap stocks

Low-float + cheap can move hard, but it also produces: - slippage - fakeouts - emotional decision-making

4) Participation (RVOL)¶

Momentum needs attention. RVOL is a decent proxy.

Read: - Relative volume

Relative volume top list — RVOL helps you focus on names the market is actually trading today.

5) Time windows (momentum isn’t evenly distributed)¶

Define when you even evaluate momentum: - premarket - open (9:30–10:30) - power hour

Lunch is often chop.

How to avoid overfitting (the rule)¶

Pick 1–3 “noise killers”, not 12. Good options: - minimum range expansion (so you’re not trading tiny moves) - avoid extreme spreads - minimum volume today

Then stop.
