FLEX Historical Service

Update : Dec. 20, 2012


The TSE will accumulate real-time data currently provided from our FLEX Standard and FLEX Full data on a daily basis and offer this to customers as the "FLEX Historical Service."

Tick data volume has surged since the arrowhead trading system went online, and the cost of accumulating this data has increased commensurately. Since market participants need to create an internal infrastructure for quickly providing long-term historical data for algorithmic model building and back-testing, the TSE aims to decrease the burden on our clients by directly providing an environment to conveniently access historical data at any time.

Fee Schedule

1) Access fees

Users will be charged access fees for the service. These are the only fees that are charged if the information is only used for internal purposes (no restriction on the number of internal users).

The individual corporate usage rate will be applied to licensees who only use the service internally, while the group company usage rate will be applied if the licensee shares the service with group companies.

Monthly access fees are as below (in JPY, not including tax):

NO Service Individual corporate usage rate (yen) Group company usage rate (yen)
1 FLEX Standard Historical (Cash Equities) 95,000 142,500
2 FLEX Full Historical 142,000 213,000

5 FLEX Standard Historical (Futures) 60,000 90,000
6 NO1 and NO2 package 177,750 266,625

2) External distribution fees

If the licensee distributes information received to an external third party, an external distribution license fee will be applied in addition to the previously outlined access fees. These fees will be waived, however, if the licensee already pays the external distribution fee for FLEX real time information (full depth or BBO8).

Users can choose from among two payment methods when completing the contract: 1) The "pay-as-you-go" plan where licensees report the number of users on a monthly basis, or 2) The "fixed rate" plan where monthly reporting is unnecessary.

Monthly external distribution fees for each plan are as below (not including tax):
