Stop-Limit Order Display Behavior in the Open Orders page

When a Stop-Limit order is triggered, the system will automatically convert the order type from Stop-Limit to a Limit order.

When a Stop-Limit order is triggered, the system will retain the order type as Stop-Limit, and the order status will be displayed as “Triggered”. This enhancement provides clearer visibility into the order’s current state.

Order ID and Txn ID

Parent & Child Order Model

When a single order is partially matched multiple times, the system generates a new child order for each match.

• Example: 1 original order matched in 3 parts > 3 Order IDs and 3 txn_ids are generated.
  
  

Order & Match Model (Global Exchange Concept)

When a single order is partially matched multiple times, no new orders (child orders) will be created. All matches will occur under the original order. (Order ID can match multiple times.)

• Example: 1 original order matched in 3 parts > 1 Order ID and 3 txn_ids will be generated.

Order_id and Txn_id type

The symbol name and side are specified in the ID.

• Example: BTCBUY12123312323

Changed to UUID type, where the symbol name and side are no longer specified in the ID.

• Example of the new UUID:  67b03a32a713c3f75f707799
