Scalping

Scalping profits from the natural bid-ask bounce and micro-movements in price that occur thousands of times per day. Here is how a typical scalp trade plays out:

1. Identify a liquid stock with tight spreads (penny or sub-penny). The bid-ask spread is the scalper's primary cost — a $0.03 spread on a trade targeting $0.10 profit means 30% of the gain is lost to spread friction before the trade even moves in your favor.

2. Wait for a setup — a pullback to VWAP, a bounce off a key level, or a tape reading signal (sudden large buy orders on the Level 2 screen).

3. Enter with size — scalpers often use larger position sizes (1,000+ shares) because the per-share profit is small. Buying 2,000 shares of a $50 stock for a $0.20 target = $400 profit per trade.

4. Exit quickly — within seconds to a few minutes. Scalpers use hard stops (often just $0.05-$0.15 below entry) and take profits as soon as the target is hit. There is no "letting winners run" in scalping — the edge comes from consistent small wins.

5. Repeat — a scalper might execute 50-200 trades per session, each following the same disciplined process.

1. Bid-Ask Bounce: In range-bound stocks, buy at the bid and sell at the ask repeatedly. This works best in high-volume stocks with a $0.01 spread. Profit is small per trade but compounds with volume and frequency.

2. VWAP Scalp: Enter long when price dips to VWAP and shows a rejection candle on the 1-minute chart. Target 0.5-1x ATR above VWAP. This works because VWAP is where institutional algorithms accumulate, so it acts as a magnet.

3. Level 2 / Tape Reading: Watch the order book (Level 2 data) for large iceberg orders or sudden spikes in bid volume. Enter in the direction of the large order and ride the momentum as other participants react. This is the most skill-intensive form of scalping.

4. Opening Range Scalp: During the first 5-15 minutes of the session, stocks establish a range. Scalp the breakout from that range with a tight stop inside the range. The first 30 minutes provide the highest volume and most predictable momentum of the day.

5. News Scalp: When breaking news hits (earnings beat, FDA approval, CEO departure), stocks gap and run. Scalpers enter the momentum move on the first pullback and exit quickly. Requires a real-time news feed and sub-second execution.

Broker requirements: You need a direct-access broker with per-share commissions (not per-trade). At 100+ trades per day, a $5 per-trade commission would cost $500/day, destroying any edge. Brokers like Interactive Brokers charge $0.0035 per share, making high-frequency trading economical.

Technology: A reliable, low-latency trading platform with hotkey execution. Scalpers configure keyboard shortcuts for instant market orders — there is no time to click through order entry screens. Many use platforms like DAS Trader, Sterling Trader, or IBKR TWS with custom hotkeys.

Account size: The PDT rule requires $25,000 minimum for pattern day trading in the US. Scalpers typically need $30,000-$50,000 to absorb the daily fluctuations and commission costs. Below $25,000, you are limited to 3 day trades per rolling 5-day period, which makes scalping impossible.

Market data: Level 2 quotes and time-and-sales (tape) data are essential. The basic Level 1 quotes (best bid/ask) are insufficient — scalpers need to see the full order book to identify institutional activity and order flow.

Mental stamina: Scalping requires intense focus for 2-4 hours straight. Most scalpers focus on the first 2 hours (9:30-11:30 AM ET) and the last hour (3:00-4:00 PM ET), when volume and volatility peak.

Scalping: Hold time of seconds to minutes. Targets $0.05-$0.50 per share. Dozens to hundreds of trades per day. Win rate target: 65-80%. Uses 1-minute and tick charts. Requires constant screen time.

Day Trading: Hold time of minutes to hours. Targets $0.50-$5+ per share. 3-10 trades per day. Win rate target: 50-60% with higher R multiples. Uses 5-minute and 15-minute charts. Requires active monitoring during market hours.

Swing Trading: Hold time of 2-20 days. Targets $2-$20+ per share. 2-5 trades per week. Win rate target: 40-55% with 2:1+ R multiples. Uses daily and 4-hour charts. Can be managed in 30 minutes per day.

Scalping has the highest win rate but smallest wins per trade. Swing trading has the lowest win rate but largest wins. Day trading sits in between. The total expected value can be similar across all three — the difference is in temperament and lifestyle.

Most professional traders start as scalpers (to learn market microstructure) and eventually transition to day trading or swing trading as they grow their accounts and want better quality of life.

Studies suggest that 80-90% of retail scalpers lose money. The common failure modes:

Commission drag: Trading 100+ times per day, even small per-share commissions compound into a significant percentage of gross profits. A scalper grossing $500/day might pay $150-$200 in commissions, requiring a much higher gross win rate to stay net positive.

Spread cost: The bid-ask spread is a hidden tax on every trade. On illiquid stocks with $0.05+ spreads, the spread cost alone can exceed the target profit.

Overtrading: The adrenaline of rapid-fire trading leads to "revenge scalping" — taking impulsive trades after losses to recover, which compounds losses.

Slippage: In fast markets, market orders may fill 1-3 cents worse than expected. On a $0.10 target, that slippage cuts the profit by 10-30%.

Psychological burnout: Scalping requires peak concentration for hours. Mental fatigue leads to increasingly poor decisions as the session progresses. Most successful scalpers trade only 2-3 hours and then stop.
