What service can be utilized by traders whose systems are temporarily down?

The trading on behalf service is designed to assist traders whose systems are temporarily down or unavailable. This service allows an authorized individual or institution to execute trades on behalf of the affected trader, ensuring that their trading strategies can continue to be implemented even when the trader is unable to actively participate in the market.

This service is particularly beneficial in situations where time-sensitive trades or market conditions require immediate attention. By utilizing this service, traders can prevent potential losses or missed opportunities, which might occur due to technical issues with their own trading platforms. It allows for continuity in trading operations, which is crucial for maintaining investment objectives and adhering to predefined trading plans.

Other options like an emergency stop-loss service or a manual trading assistant provide support but do not offer the comprehensive capability of directly executing trades on behalf of a trader facing technical difficulties. The auto-trade feature, while it can automate trading strategies, would not be effective if the trader's systems are entirely down. Therefore, the trading on behalf service stands out as the most relevant option for the scenario presented.
