TL;DRA trading style focused on capturing small, fast profits with high frequency. Scalpers hold positions for seconds to minutes, targeting 2-8 ticks per trade. Requires fast execution, low commissions, and exceptional discipline.
Scalping is the fastest active trading style. Scalpers enter and exit positions within seconds to minutes, targeting small per-trade gains (typically 2-8 ticks on ES, or $25-$100 per contract) with high frequency.
The premise is simple: take many small profits throughout the day. A scalper might execute 20-50 trades per session, each capturing a few ticks. The edge comes from reading short-term order flow, reacting to micro-level supply and demand, and maintaining an extremely high win rate.
Execution speed matters in scalping more than any other style. You need a fast platform with one-click order entry, low-latency data feeds, and a broker with competitive commissions. Even one extra tick of slippage per trade compounds into hundreds of dollars over a full session.
Commissions must be low. If you're paying $4 round-trip per ES contract and making $25 per trade, commissions eat 16% of your profits. Negotiate with your broker if you're doing high volume.
Screentime is intensive. Scalpers watch the DOM, time and sales, and tick charts continuously. This is not a part-time activity. Most successful scalpers trade the first 2-3 hours of RTH and then stop.
Scalping typically uses 1:1 or even 1:0.75 risk-reward ratios. This means the strategy depends entirely on a high win rate, usually 55-70%. If your win rate drops below 50% on a 1:1 ratio, you lose money.
This is the opposite of swing trading, where you might have a 35% win rate with 1:3 risk-reward. Scalping is about accuracy and consistency, not big individual winners.
Because of the tight risk-reward, every cost matters: commissions, slippage, and the bid-ask spread all take a larger percentage bite out of a 4-tick winner than out of a 40-tick winner.
Scalping suits traders who can make fast decisions under pressure, have excellent focus for 2-4 hours straight, and don't get emotionally attached to individual trades.
It does not suit traders who want flexible schedules, struggle with rapid decision-making, or have difficulty taking small losses quickly. The emotional cost of 20-50 decisions per day is significant.
Most trading educators recommend starting with swing trading or day trading on higher timeframes before attempting scalping. The skills required for scalping build on foundational trading competencies.
Typical scalping session
You scalp ES during the first 90 minutes of RTH. You take 15 trades targeting 4 ticks ($50) with a 4-tick stop.
Win rate: 60% (9 winners, 6 losers). Winners: 9 x $50 = $450. Losers: 6 x $50 = $300. Gross P&L: $150. Commissions: 15 trades x $4.50 round-trip = $67.50. Net P&L: $82.50. Margins are thin, and a few extra losses flip the day negative.
Commission impact on scalping
Two scalpers both make $300 gross in a session of 25 trades. Trader A pays $4 round-trip, Trader B pays $2.
Trader A's commissions: 25 x $4 = $100. Net: $200. Trader B's commissions: 25 x $2 = $50. Net: $250. Trader B keeps 25% more profit on the same gross P&L. At this frequency, commission rate is a competitive advantage.
Scalping without considering commission costs
Calculate your breakeven before starting. If commissions are $4 round-trip and your average winner is $50, you need a 52%+ win rate just to break even. Lower commissions improve your edge significantly.
Trying to scalp during low-volatility periods
Scalping requires price movement. If ES is grinding sideways in a 5-point range, there aren't enough ticks to capture. Scalp only when the market is moving.
Not having a hard daily loss limit
Scalping can spiral. One bad trade leads to revenge trading, which leads to overtrading. Set a daily loss limit (e.g., -$200) and stop trading when you hit it.
