Scalping, microscalping, and high-frequency trading

Short-term trading is allowed when it reflects realistic execution. Strategies intended to exploit simulated fills, delayed prices, or system behavior are not permitted.

Microscalping targets very small price moves over brief holding periods, sometimes using larger positions. Boxcar distinguishes genuine short-term trading from attempts to exploit simulated execution.

An account can be flagged when more than 50% of its profits come from trades held for five seconds or less. A flag prompts review of the trading pattern; it is not the same as an automatic drawdown breach.

A trained reviewer checks flagged activity before deciding whether it is bad-faith microscalping. If confirmed, Boxcar may issue a written warning. If the flagged behavior continues after a warning, profits attributable to that microscalping activity are forfeited and access may be permanently restricted. The warning, later trades and affected profits must be documented; the threshold alone never causes forfeiture.

High-volume automated trading designed to exploit extremely short-lived price or execution differences is prohibited. Allowing automated strategies does not make high-frequency exploitation acceptable.

A warning can be followed by profit removal, account closure, and loss of access for repeated behavior.

You may appeal a microscalping finding you believe is incorrect. Contact support with the affected account, trade dates, order or trade identifiers, holding times, and a short explanation of the strategy. Include relevant logs or screenshots, but never your password. Boxcar reviews the appeal and records its outcome before a final adverse microscalping decision.
