Options trading entails significant risk and is not appropriate for all customers. It is important that investors read Characteristics and Risks of Standardized Options before engaging in any options trading strategies. Options transactions are often complex and may involve the potential of losing the entire investment in a relatively short period of time. Certain complex options strategies carry additional risk, including the potential for losses that may exceed the original investment amount. Supporting documentation for any claims, if applicable, will be furnished upon request.

Futures live trading is currently only available for trading accounts with Moomoo SG or FUTU HK and is not yet supported by accounts with Moomoo US or Moomoo AU. Futures trading involves high risks and is not suitable for all investors. The amount you could lose may be greater than your initial investment.

Losses can happen more quickly with quant and algorithmic trading compared to other forms of trading. Trading in financial markets carries inherent risks, making effective risk management a crucial aspect of quantitative trading systems. These risks encompass various factors that can disrupt the performance of such systems, including market volatility leading to losses.

Moreover, quants face additional risks such as capital allocation, technology, and broker-related uncertainties. It's important to note that automated investment strategies do not guarantee profits or protect against losses.

The responsiveness of the trading system or app may vary due to market conditions, system performance, and other factors. Account access, real-time data, and trade execution may be affected by factors such as market volatility.
