Order Types

Only limit orders (i.e. orders which can be matched at the specified price or a better price) will be accepted for SSE Securities and SZSE Securities throughout the day. 

Price Limit

For SSE Securities, there is a general price limit of ±10% (and ±5% for stocks under special treatment (i.e. ST and *ST stocks) under risk alert) based on previous closing price.

All orders input for SSE Securities must be at or within the price limit. Any order with a price beyond the price limit will be rejected by SSE. The upper and lower price limit will remain the same intra-day.

The same price limit arrangement applies to SZSE Securities. Stocks traded on SZSE’s ChiNext Market are also subject to a ±10% price limit based on the previous closing price.
