Market Maker Scheme
Update : May 02, 2013
1. What is the Market Maker Scheme
The Market Making Scheme is a system that creates a trading environment where market makers continually quote bids and offers for designated contracts so that investors can trade the contracts at any time.

4. Request for Quote
TSE has established a request for quote (RFQ) system to ensure smooth trading of contracts, for which market makers do not provide bids and offers.
By indicating the targeted contract (including strategy transactions) and the amount (optional) through the RFQ system, investors can receive bids and offers from the market makers of the relevant underlying assets.
