[J-GATE3.0] Is there a case that orders can be sent although Order rate limit (Limit for number of new orders rate per time period) set in TradeGuard has been exceeded?

Is there a case that orders can be sent although Order rate limit (Limit for number of new orders rate per time period) set in TradeGuard has been exceeded?

Answer

Order Rate Limit is Breached when a tenth of the set Limit is exceeded within a tenth of a second.
However, it is not always calculated precisely every tenth of a second. There could be cases where orders are processed before TradeGuard risk check takes effect, for example when a large number of orders are entered.
 
In the example below, orders may be placed without Breaching.
1. Cases that orders can be placed
(a)Number of orders sent in 1/10 seconds in participant's system exceeds Order rate limit
or
(b)Number of orders sent in 1/10 seconds in J-GATE exceeds Order rate limit
-However, if the number of orders placed in 1/10th of a second measured based on the data TradeGuard receives from J-GATE does not exceed the limit of Order Rate Limit.
 
In the example below, orders may not be placed due to a Breach*.
2. Cases that orders cannot be placed.
(a)Number of orders sent in 1/10 seconds in participant's system does not exceed Order rate limit
(b)Number of orders sent in 1/10 seconds in J-GATE does not exceed Order rate limit
- However, if the number of orders placed in 1/10th of a second measured based on the data TradeGuard receives from J-GATE exceeds the limit of Order Rate Limit.

*In order to avoid this, please consider to set TradeGuard's Order Rate Limit to a value that is somewhat larger than the number of orders per tenth of a second controlled by the user's system.
