It depends on whether the platform is formal. If you are a regular platform, this will not happen, because the list is in the international market. The formal platform only charges you a handling fee, and the profit and loss have no effect.

The delay may be when the market is relatively large at the time of trading, and there are many reasons to delay placing orders for a period of time. There is a network, a big market and a black platform, all of which are reasons. The main thing is to judge for yourself.
