IG Japan reports two-hour order-execution incident involving incorrect prices and delays

IG Securities Japan says some customer orders were executed at abnormal prices or experienced processing delays between approximately 03:30 and 05:30 JST on 29 October. Its Japanese-language systems notice says the problem was resolved at about 05:30, while checks of affected customers and transactions were continuing.[1]

The stated interval converts to approximately 18:30–20:30 UTC on 28 October. The previous-day UTC date follows from Japan’s nine-hour offset; the broker’s local incident date remains 29 October.[1]

IG said it would contact customers individually where a response was required. It did not publish the number of affected accounts, quantify customer losses or announce a general compensation rate. Nor did the notice identify a technical root cause.[1]

A separate entry on the same page concerns notification emails and SMS login codes on 30 October, with service restored around 11:30 JST. That notice describes a different function and date; it does not establish that the earlier order-execution incident continued into a second day.[1]

The account-level review is the remaining substantive issue. The public notice establishes a reported service incident and its approximate duration, but it cannot determine the outcome of an individual trade.[1]
