The liquidity contract shall at least prescribe the following matters with respect to the responsibilities and obligations of a liquidity provider:
- The calculation formula for the best bid/ask spread of the ETF as disclosed in the TWSE centralized securities exchange market is as follows:
(the best bid/ask spread) = [(lowest unexecuted ask quote) - (highest unexecuted bid quote)]/( lowest unexecuted ask quote)
- The minimum number of participations by a liquidity provider in matching of the ETF. The number of participations in matching means the designated minimum number of participations in matches in the TWSE's trading system in a buy or sell order in which the price is within a specified range above the previous lowest unexecuted ask quote, within a specified range below the previous highest unexecuted bid quote, or within a specified range above and below the execution price. Minimum numbers shall be set for participations in matches of bid and ask quotes calculated as specified above.
- The minimum amount of buy/sell quotes that a liquidity provider shall make during a suspension of matching when there occurs a circumstance specified in paragraph 4 of Article 58-3 of the TWSE Operating Rules with respect to the ETF during the trading session.
- Except when the price of the ETF goes limit-up or limit-down, the disclosure of market trading prices is limited only by the duration of time of bid or ask prices; however, the aforesaid calculation of time may be excluded when matching time must be postponed due to a circumstance specified in paragraph 4 of Article 58-3 of the TWSE Operating Rules.
- Agreement that the TWSE provide to the SITE or the general agent for offshore funds all the buy/sell quotes and itemized statements of trading of the ETF done through the liquidity provider's segregated ETF account.
