While most of us hang around waiting for the opening bell to ring, the savviest traders are already spotting momentum before 9:30am ET. Whether you're preparing for an earnings reaction, watching for economic data surprises, or tracking global news, pre-market and post-market sessions give you a head start.

In this step-by-step guide, we’ll show you how to use Barchart’s tools to scan, screen, and get alerts before and after hours — and why this matters more than ever in volatile conditions.

Step #1: Understand Why Pre- & Post-Market Matters

• Pre-market trading happens between 4am–9:30am ET.
• Post-market trading runs from 4pm–8pm ET.
• Major news catalysts moving stocks during these hours can include earnings reports; guidance updates; overseas rate changes; geopolitical headlines; and jobs data.

Why it’s important:

• Big funds sometimes move positions in after-hours.
• Earnings reactions often start before and after the bell.
• Traders watching these moves can prepare for extended volatility, or be ready to capitalize on reversals.

Step #2: Visit Barchart’s Pre-Market & Post-Market Pages

• Pre-Market Trading
• Post-Market Trading

You’ll see:

• Top gainers and losers
• Most active stocks by volume
• Price gaps up or down
• Custom filters to screen lists by exchange, sector, and more

Pro Tip: Sort by Volume or Percent Change to quickly identify momentum.

Step #3: Use Screens and Filters to Customize

Click “Screen” at the top of either page to filter based on your trading style.

Recommended Filters:

• Price: Above $10 (eliminate low-dollar and penny stocks, unless that’s your niche)
• Volume: Over 1,000,000 (to find active names)
• Market Cap: Large & Mega-Cap (for stability and reliability)
• RSI or MACD Signals: Spot overbought or oversold setups
• Gap Up / Gap Down %: To catch extreme overnight moves

Barchart Premier members can unlock even more technical features and trade alerts.

Step #4: Analyze Setups with FlipCharts

After filtering your list, open the FlipCharts view.

• Use chart templates for different strategies
• Look for key technical patterns like breakouts, gaps, and reversal levels
• Save setups to a Watchlist for later review

Pro tip: Use daily and weekly views to compare short-term movement vs. longer trends.

Step #5: Save the Screener + Set Trade Alerts

Once you've customized your screener:

• Click “Save Screener”
• Set up email alerts when new stocks meet your criteria
• Name and save a Watchlist to track entries and exits

With Barchart Premier, you can even track strategy-based setups like moving average crossovers or TrendSeeker signals with exclusive trade alerts.

Final Tips: What the Pros Watch in Pre-Market

• Volume early in the session: Spikes in pre-market often indicate news
• Gap-ups on strong earnings: Confirm direction with volume and RSI
• Gap-downs on weak guidance: Watch for support levels and future reversals
• Sector-based movement: Energy, tech, and financials often react to macro news in after-hours trading
