📖 Forex scalping: basics, conditions and key risks
Forex scalping is ultra‑short‑term trading: dozens of quick trades per day with profit taken from tiny price moves. For retail traders it can sound like a “fast” path to results, but in practice it hinges on spread, commission, execution stability, and discipline.
This guide explains when scalping actually works for retail, which conditions are required (liquidity, spread, commission, execution model), where it is permitted by brokers, and which risks and psychological constraints to consider.
What scalping is and how it differs from day or swing trading
Scalping is a series of very short trades (seconds to minutes). Critical factors: input speed (one‑click, hotkeys), all‑in cost per trade (spread + commission), and execution predictability (low latency, stable liquidity).
M1–M5: one‑ to five‑minute chart timeframes. The lower the timeframe, the higher the sensitivity to costs and latency.
R/R: risk/reward ratio in a trade (e.g.,
Differences: day trading lasts minutes to hours (positions closed the same day) and is less sensitive to tenths of a pip; swing trading spans days/weeks and is hardly affected by the spread of any single trade. For a scalper, even a small deterioration in spread/commission/slippage cuts expectancy.
Scalping constraints: liquidity, execution, spread, and commission
Spread: the Bid/Ask difference — your starting deficit on entry. Narrower spread = a smaller initial negative.
Commission: fixed fee per volume on ECN/Raw accounts. On “no‑commission” accounts, the fee is often embedded in a wider spread.
Slippage: the fill occurs at a worse/better price than requested. Increases around news and in a “thin” market.
Requote: a price re‑request if the quote changes before execution. A sign of unstable execution.
Last look: the liquidity provider’s right to reject a fill when the price “runs away.” A source of negative slippage.
Liquidity and filters
Scalping works only on dense liquidity: the more limit orders at the best levels, the higher the chance of getting your planned price.
- Market depth: dense bids and offers reduce slippage.
- LP filters: on sharp ticks an order may be partially filled or rejected.
- News windows: liquidity drops abruptly, negative slippage increases.
Execution and latency
For a scalper, predictable execution and minimal latency (ping) are essential.
- Infrastructure: a VPS near the broker’s server, stable internet, backup access.
- Tools: one‑click entry, DOM (Depth of Market) for precise entries.
- Metric: regularly check actual ping and terminal stability.
Spreads and commissions
A scalper’s main costs are spread, commission, and average slippage. Optimizing them is critical.
- Raw/ECN accounts: narrow spreads with explicit volume‑based commissions.
- Break‑even threshold: with 3–7‑pip targets, an extra 0.3–0.5 pip can consume a third of expectancy.
- Practice: compute the all‑in round‑trip cost in your trading hours and pairs.
When scalping makes sense for retail
- Instruments: EUR/USD, GBP/USD, USD/JPY — minimal spreads, deep liquidity.
- Time: London–New York overlap; intraday windows with dense order flow.
- Market: directional impulses or stable ranges; avoid chop and micro‑ranges.
- News: only with a plan and infrastructure (VPS, bracket orders, tests based on your own stats).
Minimum requirements
- Account: ECN/Raw or STP/NDD; transparent volume‑based commissions instead of a spread mark‑up.
- Spread: statistically narrow in your hours (collect 2–4 weeks of data).
- Commission: the all‑in round‑trip cost fits your setup targets.
- Platform: one‑click, hotkeys; MT5/cTrader with DOM.
- Infrastructure: VPS near the broker’s server; stable connection; backup.
- Rules: no minimum holding time and no limits on trade frequency.
VPS: a virtual server near the trading server — reduces latency and outages. Provides stability for active trading.
Ping/latency: terminal ↔ server delay. The lower it is, the closer fills are to your planned price.
DOM (Depth of Market): the limit‑order book by price levels. Shows liquidity density and “thin” areas.
Setting up a scalper’s workspace
- Choose an ECN/Raw account for scalping; verify actual spreads, commissions, and slippage in your hours.
- Configure the terminal: hotkeys, SL/TP presets, quick buttons for partial profit‑taking.
- Deploy a VPS near the broker’s server; measure ping and stability on live flow.
- Collect 2–4 weeks of cost and setup statistics; keep a trade journal.
- Define risk parameters: per‑trade stop, daily limit, and a “timeout” after a stop streak.
Scalping
Principle: ultra‑short‑term trading with dozens of trades per day to capture small price fluctuations.
- Who it suits: traders with high concentration who can operate “here and now.”
- When it’s appropriate: on highly liquid pairs with narrow spreads and fast infrastructure.
✅ Pros
- Fast feedback: mistakes and improvements are visible the same day.
- Low overnight exposure: positions are not carried overnight.
- Flexible adaptation: spread/time filters are easy to embed in the playbook.
❌ Cons
- Cost dependence: spreads, commissions, negative slippage.
- High discipline demands: risk of overtrading and emotional decisions.
- Infrastructure required: VPS, stable internet, fast terminal.
Key point: scalping helps you accumulate experience quickly and keep risks short, but it demands impeccable discipline and minimal costs.
Where scalping is allowed: the execution model matters more than the brand
| 🤝 Broker | ⚡ Execution | 💰 Spreads | 💳 Commission |
|---|---|---|---|
| RoboForex | ECN‑Pro (NDD) | from ~0 pips | fixed per volume (Raw) |
| FxPro | NDD (cTrader) | from ~0 pips | fixed per volume |
| Forex4you | Pro STP (NDD) | from ~0.1 pip | fixed per volume |
| FXOpen | ECN / STP | from ~0 pips | ECN: fixed; STP: in spread |
| Finam | DMA/NDD | narrow on majors | % of turnover |
How much does one scalp cost?
| Pair | Spread (pips) | Commission | Slippage (pips) | Target (pips) | Break‑even (pips) |
|---|---|---|---|---|---|
| EUR/USD | 0.3 | $7 / 1 lot |
0.2 | 5 | 0.3 + 0.2 + commission |
The scalper’s execution stack: shorter chain — fewer problems
Terminal and hardware
- Input speed: one‑click, hotkeys, order presets.
- Performance: no freezes; disable “heavy” indicators during the session.
- Backup: a second terminal/account for emergency exits.
VPS near the broker’s server
- Low ping: host in the same data center/region as the trading server.
- Stability: monitor latency and packet loss; keep backup access (RDP/VNC).
- Security: separate user; auto‑updates disabled during trading hours.
Broker server → liquidity aggregator
- Routing: direct access to LP pools (NDD/ECN/STP) without manual dealing.
- Filters: on sharp ticks, partial or rejected orders (price deviation) are possible.
- Last look: some LPs may refuse “runaway” prices — a source of negative slippage.
Liquidity providers
- Depth: dense bids/offers → less exit slippage.
- News: during releases, liquidity thins, spreads widen, slippage grows.
- Practice: keep stats of actual fill prices by pair and time of day.
LP (Liquidity Provider): a liquidity source through which orders are executed.
DOM (Depth of Market): the order book by price levels; helps assess market density.
Last look: an LP’s right to reject execution during rapid price moves while routing.
Ping/latency: terminal ↔ server delay; critical for 3–7‑pip entries.
Scalper’s playbook: working patterns
Asian Range Breakout (AR Breakout)
Trade the break of a narrow overnight range with confirmation from momentum and tick activity.
- 🎯 Entry: buy stop above the high / sell stop below the low; filter false breaks with an impulse filter.
- ⛔ Stop: beyond the range boundary.
- 💰 Exit: fixed target
1:1–1:1.5 or a quick trail. - 🚫 Filter out: widened spread or a “thin” market — skip.
Asian range =
Trend pullback (to EMA20)
Short‑term, with‑trend entry after a pullback to EMA20 (20‑period exponential moving average); confirmation via an impulse candle or micro‑structure.
- 🎯 Entry: market/stop on momentum resumption after the pullback.
- ⛔ Stop: beyond the local swing.
- 💰 Exit: fixed target
1:1–1:2 or partials. - 🚫 Filter out: range‑bound chop and lack of directional flow.
A scalper’s daily routine
- Pre‑market: news calendar, levels, focus pairs, check spread/latency.
- Session: trade only your setups, cap the number of losing entries, pause after a streak, control frequency.
- Post‑market: export trades, take screenshots, review metrics, update cost statistics.
Risk policy for scalping
- Per‑trade limit: fixed % of equity; place a stop‑loss at entry.
- Daily stop: once hit, stop trading until the next session.
- Frequency: no more than N consecutive losing entries; then a mandatory pause and review.
- Size: scale up only after 20–30 stable sessions.
Common scalper mistakes and how to avoid them
Overtrading
- Trade and series limits; a “pause timer” after a stop streak.
Chasing moves
- Enter only on playbook triggers; don’t chase price.
Ignoring costs
- Weekly “spread + commission + slippage” report by traded pairs/time windows.
Breaking the daily stop
- Auto‑alert/blocking script; emotions journal.
How to measure scalping performance
The basics
Key metrics that show how systematic and reproducible your trading is.
- Win rate: percentage of winning trades.
- Average win/loss: average result in pips.
- Commission: total round‑trip costs in pips.
- Slippage: average execution slippage.
- R/R: setup risk/reward ratio.
Trade expectancy
An objective expectation of the strategy that shows whether it is profitable over time.
- Formula:
E = Win% × AvgWin − (1 − Win%) × AvgLoss − Costs . - Application: calculate separately for each pair and session.
- Cross‑check: regularly compare actual results with the theory.
Control
Review metrics regularly so the strategy doesn’t drift toward zero.
- Reporting: weekly report by pairs.
- Updates: record spread, commission, and slippage.
- Filters: if expectancy approaches zero, tighten entry conditions.
Market liquidity by session (guidelines)

Conclusion
Scalping can work for retail if three pillars are in place: infrastructure (VPS, low latency, fast terminal), a suitable account/broker (ECN/Raw with transparent commission, no restrictions), and discipline (risk parameters, limits, journal). Missing any of these quickly drives expectancy negative.
If you prefer a calmer pace and less dependence on costs, consider day trading or swing trading.
