Explicit bans on scalping have become rare, partly because they are bad marketing and partly because the same effect is achieved through terms that read as ordinary operational rules. The result is that a trader can open an account, develop a method, and discover months later that it falls outside terms they accepted at signup.
The clauses that constrain short-term trading
- A minimum holding period before a position may be closed without review.
- A minimum distance stops and limits must sit from the current price.
- A window around scheduled announcements in which orders may be treated differently.
- A general clause on latency arbitrage and abusive trading, defined broadly.
Minimum holding time
Some brokers specify that positions closed within a stated period — often between one and three minutes — may be reviewed, adjusted or excluded from certain arrangements such as rebates or bonuses. A smaller number void profits from such trades entirely.
The stated rationale is that very short holding periods are associated with latency arbitrage, where a client exploits a delay between the broker's price and the underlying market. That is a genuine concern for a broker, and it is also a description that catches any legitimate scalping method as collateral.
The clause is worth reading carefully because its consequences vary enormously: excluding such trades from a rebate scheme is a commercial detail, while voiding their profits is a fundamental constraint on the strategy.
Minimum stop distance
A requirement that stops and limits sit at least a stated number of points from the current price is common on fixed-spread and instant-execution accounts. It is presented as a technical constraint, and it is one — but it also makes any method with a tight stop unimplementable.
A trader whose structural stop is eight points away cannot place it on an account requiring ten. The method does not become unprofitable; it becomes impossible, and the discovery usually happens at the order ticket rather than in the terms.
Check the stop distance before choosing the account type
This is one of the few constraints that can be verified in thirty seconds: open a demo of the exact account type, try to place a stop at the distance your method needs, and see whether the platform accepts it.
News windows
Terms around scheduled announcements take several forms. Margin requirements may be raised in advance. Spreads may widen without limit. Orders placed within a window of the release may be subject to review, and in some agreements, adjustment of the fill price.
The last of these is worth identifying specifically. A clause permitting the broker to adjust a fill after the fact — on the basis that the price was not representative of the market — transfers the outcome of the most volatile moments to the broker's judgement. It exists to protect against genuinely erroneous prices, and it is also a discretion.
Abusive trading clauses
Nearly every client agreement contains a clause on abusive or manipulative trading, and nearly all are drafted broadly. They typically cover latency arbitrage, exploitation of pricing errors, and coordinated trading across accounts.
Broad drafting is defensible: a narrow definition would be gamed. It does mean the boundary is set by the broker's interpretation rather than by a bright line, and that a strategy which is unusually profitable in an unusual way may attract review even where nothing improper occurred.
The practical mitigation is not to avoid profitable strategies but to understand that fill quality and profitability at a broker are related: a method that consistently profits from the broker's pricing rather than from the market will eventually be noticed, and the remedy the agreement provides is the broker's.
Finding the terms
Where these clauses actually live
- The client agreement — search for "scalping", "arbitrage", "abusive" and "holding".
- The contract specifications — minimum stop distance, per instrument.
- The order execution policy — treatment of orders in volatile conditions.
- The bonus or rebate terms, where short trades are often excluded.
- Any separate document referenced by the agreement, which is where the specifics usually sit.
If a method depends on short holding periods or tight stops, these documents are not optional reading. They are the difference between a strategy that works at a broker and one that works until someone reviews it.
Choosing a broker for short-term trading
Brokers that welcome scalping generally say so plainly, offer raw-spread pricing, market execution and no minimum stop distance, and do not impose a holding period. Those four properties together are more informative than any marketing claim, and each is verifiable from the specification and a demo account.
The absence of the claim is not evidence of a ban. But the presence of a minimum stop distance and a holding-period clause together is a reasonable indication that short-term methods are not what the account was built for.
Common questions
Is scalping banned by most brokers?
Explicit bans are rare. Constraints are achieved through minimum holding periods, minimum stop distances and clauses on abusive trading, which have the same effect on some methods.
What is a minimum stop distance?
A requirement that stops and limits sit at least a stated number of points from the current price. Common on fixed-spread and instant-execution accounts, and it makes tight-stop methods unimplementable.
Can a broker void my profits from a fast trade?
Some agreements permit it where the trade falls under a latency arbitrage or abusive trading clause. This is disclosed in the client agreement and varies from exclusion from rebates to voiding the profit entirely.
Can I trade the news at any broker?
You can place orders, but terms vary: raised margin requirements, unlimited spread widening, and in some agreements a right to review or adjust fills placed within a window of the release.
