VWAP (volume-weighted average price). In cases of extreme volatility, Circuit Breakers is applied for small-cap stocks.

==== Auction Mechanisms ====

=== Open ===

The opening session is the period of time in which orders conveyed to the exchange are matched prior to the session. The opening price is the price calculated according to the transactions that take place during the opening session. The opening time and period of the opening sessions, the trading method to apply during the opening session, and principles of calculating opening price are determined by the Executive Council of the Exchange. 

=== Close ===

The closing price is defined by the following auction mechanism.

**Auction** means an auction conducted in a trading platform in respect to qualifying orders to determine the auction price pursuant to the following process:

  * All unmatched orders entered during the main trading session will be transferred to the closing session
  * New closing orders will be accepted
  * Closing price will be determined at the level that allows the highest trading volume
  * All orders will executed at the closing price under price/time priority

**Auction Periods**

1. **Opening Auction** (09:55 - 10:00)
  * Regular trading orders may be entered, amended, and cancelled
  * Regular trading orders will be matched

2. **Closing Auction** (18:01 - 18:10) 

  * **Order Collection Phase** (18:01 – 18:04:45) 
    * During this 3-minute period, orders are collected for the closing session, while orders that have been already sent may be modified, split, or cancelled in accordance with the current regulations. The max/min limits are capped with +/- 3% of the last print for each stock. Traders can send aggressive Limit or Market orders to participate during this time.
  * **Closing Price Determination and Closing Session Transactions Phase** (18:05 – 18:07 local time)
    * At this phase, the closing price is determined for the equities for which orders have been collected during the closing session, and following that, trades at closing price are realized.
  * **Trades at Closing Price Phase** (18:08 – 18:10)
    * This is the final phase, where new bid and ask orders priced only with the closing price determined during the closing session can be entered to the trading system and can be matched with the pending orders at closing price that have not been executed during the closing session and transferred to this phase, or with those orders entered during this phase, in accordance with priority rules.
     
**Order Types:** Market and Limit orders are eligible to participate in the Closing Auction.
