Pre-Trade Risk Management

Pre-Trade Risk Management

Lime Trading Gateway has been designed and implemented to meet the outlined regulatory controls contained within Rule 15c3-5, which include all pre-trade risk validation requirements. All account rules have been uniquely coded to minimize latency. These rules monitor risk associated with buying power, buying power factor, maximum order size, maximum position size, P&L loss thresholds, short checking, odd lot allowances/restrictions and settings to reject all incoming orders. Lime Trading Gateway prides itself on being brutally efficient. Lime Trading Gateway demonstrates that pre-trade risk controls can be implemented without compromising the strategies of even the most latency-sensitive traders.
