Scalping: Cost and Execution Requirements

Scalping holds positions for seconds to minutes, capturing tiny moves repeatedly. It looks easy — small targets, frequent wins. The reality is that scalping is the most execution-sensitive style and the one where costs most often exceed edge. If your setup does not meet the cost and execution bars, scalping cannot win regardless of your chart skill.

The cost math

A scalper targets 2–5 pips on FX or 1–4 ticks on futures. Costs are the entire game. On EUR/USD:

• A typical retail spread of 1.2 pips plus 0.7 pip commission = 1.9 pips per round trip.
• A 3-pip target net of costs = 1.1 pips. A 2-pip stop net of costs = 3.9 pips. Your real risk-reward is now 1:3.5 against you.

To scalp profitably, your all-in cost must be under 0.8 pips per round trip. That requires a raw-spread ECN account with commission under $4 per side per standard lot. Standard spread-only accounts make scalping mathematically negative-expectancy for almost everyone.

Execution requirements

• Order latency under 100ms. Market-maker and slow-broker platforms slip 1–2 pips on fast moves, erasing the edge. Use an ECN or direct-market-access broker.
• Limit-order preference. Scalpers enter on limit orders to avoid paying the spread; market orders are for exits only.
• One-click execution. You must enter, move, and close in under a second. Modular order tickets are too slow.
• VPS co-location. For FX scalping, a VPS near the broker's server (London or New York) cuts latency from 80ms to under 10ms.

Timeframe and setup

• Timeframes: 1M for trend, tick or 30-second for entry.
• Targets: 2–5 pips (FX) or 1–4 ticks (futures). Stops equally tight, 2–4 pips.
• Win rate needed: 65%+. With 1:1 risk-reward and high costs, you need a high win rate just to break even. Below 60%, scalping bleeds.

The psychological cost

Scalping is 4–6 hours of continuous high-focus execution. Most traders cannot sustain the attention beyond 90 minutes without errors. Cognitive fatigue produces slips — wrong size, wrong direction, missed exits — that cost more than the edge earns. Professional scalpers cap sessions at 2 hours and take mandatory breaks.

Who should not scalp

• Traders on spread-only retail accounts — costs make it negative-expectancy.
• Traders with latency above 100ms — execution slippage erases the edge.
• Traders who cannot sustain 90 minutes of intense focus — fatigue errors dominate.
• Traders who hold losses hoping they come back — a 4-pip stop hit ends the trade; there is no "give it room."

The bottom line

Scalping requires an ECN/raw-spread account with under 0.8 pip all-in cost, sub-100ms execution, limit-order entries, and a 65%+ win rate. Without these, the strategy is mathematically negative regardless of chart skill. Cap sessions at 2 hours, use tight stops with no room, and if your broker or attention cannot meet the bars, choose a longer style — the math will not let you win.
