Korea's bourse operator activated a buy-side sidecar for the secondary KOSDAQ market on Friday as the stock index surged.

Program trading in KOSDAQ-listed shares was suspended for five minutes at 12:55 p.m., according to the Korea Exchange (KRX).

The previous day, the KOSDAQ market saw a sell-side sidecar and a circuit breaker triggered in succession during trading, with the index plunging more than 7 percent to close sharply lower.

But the index rebounded 5.27 percent to 800.90 as of Friday afternoon, reclaiming the 800-point level just a day later.

A buy-side sidecar is triggered when KOSDAQ 150 futures rise at least 6 percent from the benchmark price and the KOSDAQ 150 index gains at least 3 percent from its previous trading day's closing level, with both conditions sustained for one minute.

周五，随着韩国股市指数飙升，韩国证券交易所运营商为二级市场 KOSDAQ 启动了买入侧挂交易。

据韩国交易所（KRX）消息，韩国创业板（KOSDAQ）上市股票的程序化交易于下午12:55暂停5分钟。

前一天，韩国创业板市场在交易过程中先后触发了卖方侧车操作和熔断机制，导致指数暴跌超过7%，最终大幅收低。

但截至周五下午，该指数反弹 5.27% 至 800.90，并在一天后重新回到 800 点大关。

当 KOSDAQ 150 期货价格较基准价格上涨至少 6%，且 KOSDAQ 150 指数较前一交易日收盘价上涨至少 3%，并且这两个条件持续一分钟时，就会触发买入侧联动。
