撤单成交是什么意思

中文版

“撤单成交”是指在股票或其他金融产品的交易中，投资者在发出买卖指令后，由于某种原因决定取消该指令，而该指令在被取消之前已经成功匹配并成交的情况。简而言之，就是在指令被完全执行之前，投资者主动撤回了交易请求，但交易系统仍然按照原来的指令完成了交易。

撤单成交的原因可能有很多，比如投资者在发出指令后，突然改变了对市场的看法，或者发现了更好的交易机会，决定取消原先的指令。此外，也可能是由于交易系统出现故障或延迟，导致投资者在指令执行前及时撤回了请求。

撤单成交对投资者来说，可能会带来一些风险和挑战。首先，如果投资者频繁地撤单，可能会增加交易成本，因为每次撤单都需要支付一定的手续费。其次，如果撤单成交发生在市场行情快速变动时，投资者可能会错过更好的交易机会。因此，投资者在决定撤单前，应该充分考虑市场情况和自身的投资目标，谨慎做出决策。

What Does "Cancelled Order Execution" Mean?

"Cancelled Order Execution" refers to a situation in stock or other financial product trading where, after placing a buy or sell order, an investor decides to cancel the order for some reason, but the order is successfully matched and executed before being cancelled. In simple terms, it means that before the order is fully executed, the investor proactively withdraws the trading request, but the trading system still completes the transaction according to the original order.

There can be various reasons for cancelled order execution. For instance, an investor may suddenly change their market view after placing an order or discover a better trading opportunity and decide to cancel the original order. Additionally, it could be due to a malfunction or delay in the trading system, prompting the investor to withdraw the request before order execution.

Cancelled order execution poses some risks and challenges for investors. Firstly, frequent order cancellations may increase transaction costs as each cancellation typically incurs a fee. Secondly, if cancelled order execution occurs during rapid market fluctuations, investors may miss out on better trading opportunities. Therefore, before deciding to cancel an order, investors should carefully consider market conditions and their investment objectives to make informed decisions.
