Pre-Event Positioning

The smartest money positions before events, not during. Here's how to build positions ahead of catalysts:

Start Arbitrage Bot

Strategy 1: Volatility Play

Before major events, buy positions on both sides if combined price is under $0.95. Events create winners, and you profit either way if spreads are tight enough.

Check YES + NO combined price
If under $0.95, buy both sides
Event moves one side to ~$1.00

Strategy 2: Underpriced Upset

Buy cheap options on potential upsets. If a long-shot candidate is at $0.05 but has a 10% chance in a debate, that's value.

Identify underpriced long shots
Small positions with high upside
Risk small amount for big payoff

Strategy 3: Fade the Favorite

Heavy favorites are often overpriced before events. Small positions against favorites can pay off when events introduce uncertainty.

Find favorites at >80%
Buy NO at $0.20 or less
Sell if price drops during event

Live Event Trading

Trading during live events requires speed, preparation, and emotional control. Here's how to execute:

Debate Trading Playbook

Pre-debate: Have orders ready on both sides. Know your trigger points.
Opening 15 min: Watch for major gaffes or standout moments. Markets often haven't fully priced early wins.
Middle section: Momentum builds. Follow the trend but don't chase extended moves.
Closing: Strong finishes matter. Final impressions drive overnight prices.
Post-debate: Wait for snap polls. Trade the narrative, not just the debate.

Election Night Playbook

Early votes: Don't overreact to initial counts. They're often skewed.
Bellwethers: Watch key counties. When they report, markets move fast.
Call timing: Know when AP/networks typically call races. Position before.
Late night: Thin liquidity. Larger spreads but also larger opportunities.

Live Trading Warning

Live event trading is high-intensity. Have a plan before the event starts. Know your max loss. Don't trade tired or emotional. Most traders lose money chasing during events.

Post-Event Strategies

After events, markets often overshoot. Post-event trading captures the reversion:

Fade the Overreaction

If a candidate drops 15% after one bad debate moment, that's often excessive. Buy the dip if fundamentals haven't changed.

Wait for Confirmation

Don't immediately counter-trade. Wait for polls or analysis. If post-event data confirms the move, it won't revert.

Position for Next Event

After one debate, start positioning for the next. Markets often offer good entry points in the calm between storms.

Event Calendar Management

Key Events to Track

1
Political Calendar

Debates, primaries, conventions, election day. Mark them months ahead.

2
Economic Calendar

Jobs (first Friday), CPI, Fed meetings, GDP releases.

3
Sports Schedule

NFL Sunday, NBA games, major soccer matches, playoffs.

4
Corporate Events

Earnings, product launches, regulatory decisions for crypto/tech markets.

Risk Management for Events

Set Maximum Event Exposure

Never risk more than 10% of portfolio on a single event outcome.

Use Limit Orders During Events

Market orders during high volatility = massive slippage. Always use limits.

Have Exit Plans Ready

Know where you'll take profits and cut losses before the event starts.

Expect the Unexpected

Events can produce surprises. Never assume you know the outcome.

Never Miss Another Event

PredictEngine alerts you to upcoming market-moving events and can execute your strategy automatically during live events.
