1.Process Following a CB Trigger

(1)CB is triggered for each contract month.

(2) For each CB trigger, the trading session will be halted for 5 minutes from the time of the trigger. Trading will then resume with an expanded CB.

(3)From the CB trigger exceeding the number of expansion set forth for each product, trading will resume after a 5-minute halt, but the CB trigger level will not be expanded.

(4)As for the Rubber market, the CB trigger level will not be expanded, in principle, from the fourth CB trigger except for the nearest contract month.

(5)When deemed necessary by the Exchange, however, the halt period and trigger level expansion may be modified.

2.Examples of CB Expansion

(1)Example for Gold (figures are in JPY)

  • CB Trigger Level after 1st Trigger = 150 (initial trigger level) + 150 (expansion amount) = 300
  • CB Trigger Level after 2nd Trigger = 300 (previous trigger level) + 150 (expansion amount) = 450
  • CB Trigger Level after 3rd Trigger = 450 (previous trigger level) + 150 (expansion amount) = 600

(2)Example for Azuki (figures are in JPY)

  • CB Trigger Level after 1st Trigger = 350 (initial trigger level) + 350 (expansion amount) = 700
  • CB Trigger Level after 2nd Trigger = 700
