1. Overview of short-term trading strategies

Short-term on Polymarket usually means hours to a few days: you’re trying to catch fast repricing—news, flow, thin books, post-headline mean reversion—not necessarily riding to resolution.

Those strategies exist; they’re also crowded. Edges are often small, short-lived, and fill-sensitive. What works around injury windows may flop in a slow political grind.

Whale prints and Smart Money matter most here: short horizons are where speed and flow dominate—and where sloppy copying gets picked off.

2. Core components (timing, liquidity, volatility)

Timing

• Scheduled catalysts — debates, prints, injuries, polls → liquidity spikes you can plan around.
• Half-life — short signals decay as the book reprices; you need stops or time rules.
• Sessions — depth often clusters when macro attention is high—measure it in your journal, don’t assume.

Liquidity

• Tight mid, no size = trap; cap participation to what the book can take.
• If your order is the move, you don’t have an edge—especially chasing late whale alerts.

Volatility

• Headlines jump prices—that’s opportunity and risk.
• Pre- vs post-news microstructure isn’t the same animal—tag regimes in your rules.

3. How short-term trading works in Polymarket

Loop it:

1. Trigger — catalyst or flow, with a time box.
2. Costs — fees, half-spread, slippage at your size.
3. How you enter — limit vs market matches urgency.
4. Exit — time stop, flow flip, opposing Smart Money, or price invalidation.
5. Review — tag alpha vs luck by category.

Whale data = early warning and invalidation: sustained Smart Money with the move can support momentum; fast unwind can mean reversion or distribution.

4. Practical example

Playbook (not advice): Liquid market, known release in ~60 minutes.

• No blind pre-bets—let the first panic spread clear if you can.
• Limits if the book stabilizes and Smart Money isn’t fighting you.
• Out if whale flow reverses in X minutes or your invalidation trades.

If you can’t watch the book in that window, don’t run this style—short-term is operational.

6. Risks and limitations

• Fees + spread can eat the whole gross edge on short holds.
• Adverse selection after headlines.
• Resolution curveballs even on “short” trades.
• Overtrading — more clicks, not more edge.
• Crowded public whale triggers decay.

---

7. Advanced insights

• Lead–lag across related markets — edge sometimes in the second contract.
• Maker/taker mix should match where your alpha comes from.
• Vol targeting — shrink size when spreads widen unless edge scales too.
• Meta-label: only trade the impulse if Smart Money confirms—cuts false positives.
