Scalping is a short-term trading style seeking small price movements through frequent entries and exits. Small targets can make spread, commission, latency and execution differences substantial relative to gross profit. A high win rate or an ECN/STP account label does not establish positive expectancy. Specify trading hours, monitoring requirements, permitted methods and all-in costs, then evaluate the full rule rather than assume a universal minimum sample or mandatory broker model. See Scalping.
Example. A hypothetical scalper makes 30 trades in a day with a +5-pip target, a −5-pip stop and a 55% win rate. Gross expectancy is 0.55 × 5 − 0.45 × 5 = +0.5 pip per trade. A modelled 1.7-pip round-trip cost reduces it to −1.2 pips per trade, or an expected total of −36 pips across 30 identically modelled trades. If an additional average 0.5-pip execution loss applies, the total cost is 2.2 pips and expectancy is −1.7 pips, or an expected total of −51 pips across 30 identically modelled trades. These are illustrative assumptions, not forecasts. Do not deduct a spread again if it is already reflected in the execution prices used to calculate the outcome.
Why small targets are sensitive to cost
Against a five-pip gross target, one pip of cost is 20% of that target. For a hypothetical standard EUR/USD lot of 100,000 EUR, one pip is USD 10. A one-pip spread, USD 7 round-trip commission (0.7 pip) and total adverse execution of 0.5 pip cost 2.2 pips. The five-pip gross gain becomes 2.8 pips after those costs, before any other fees: 44% of the gross target is absorbed by cost. A loss also becomes larger after costs.
Compare actual all-in cost and fills, rather than assume an ECN/STP label is required or sufficient. Thirty trades can reveal operational issues but do not establish statistical reliability; neither does a universal threshold of 100 trades. The sample must support uncertainty analysis and cover relevant conditions. Costs should be modelled without charging the same quote spread twice.
Partial fills and speed
With a short target, rejection, partial execution or retrying can change the entire result. Record signal, submission and fill times plus actual size. Faster hardware or a VPS can affect selected delays but creates neither liquidity nor a guaranteed fill.
Separate signal from cost
Keep session windows and valuation conventions consistent across variants. A small target can fail to produce a positive net result despite attractive gross statistics. Do not attribute every loss to psychology when execution or erroneously charging spread twice explains the discrepancy.
FAQ
Can I scalp while working full time?
It depends on working hours, the strategy and any automation. Discretionary scalping requires attention during its chosen trading window and can be difficult to combine with work. It is not categorically impossible, and a London–New York overlap is not universally required. Choose a process compatible with the time and monitoring it actually needs. Do not assume that work duties and immediate market decisions can both be handled effectively at once. Swing trading commonly needs less continuous monitoring, but still requires a plan and risk checks.
What should I look for in a broker for scalping?
Check permission for the strategy, total costs, quote and fill quality, order handling and the legal agreement. An ECN/STP label does not guarantee narrow spreads or better execution. A VPS may help a suitable automated workflow but does not establish an edge or eliminate slippage. Compare spreads during the intended trading hours, round-trip commission, slippage, rejections, available volume and delays. A 1.5-pip spread absorbs 30% of a five-pip target before any other charges.
Can a broker restrict scalping?
Contractual restrictions can concern holding periods, particular arbitrage methods or order behaviour. Read them before using the account. Do not infer restrictions solely from an A-Book, B-Book or market-maker label, and distinguish a documented rule from an arbitrary assumption about cancelled profits.
