[J-GATE]How to calculate tick size which is applicable for give up

How can we calculate tick size which is applicable for give up?
It seems that some products have tick size(Espacially J-NET) which is not applicable for give up.
Category : 

Answer

Reciprocal of Trade Multiplier could be applicable tick size for give up.
 
Trades having figures after decimal point (=less than 1 Japanese Yen) in the trading amount does not allow "give-up" as the basic rule.
So, it is necessary to decide the figure length of trading price by considering not to have figures after decimal point (=less than 1 Japanese Yen) in the trading amount.
 
For the basic rule, please refer p6 of the following document.
 
Case : Nikkei 225 Option
Tick Size : 1JPY, 5JPY, 10JPY (depend on option price)
Tick Size in J-NET : 0.0001JPY
Contract Unit :  × 1,000JPY
Trade Multiplier : 1,000
 
You can declare give up any normal trades because the tick size is more than 1JPY.
But the original tick size for J-NET is not suitable for give up because there is possible to have figures after decimal point (=less than 1 Japanese Yen), as 0.0001×1000=0.1.
 
You can declare give up if you place order with the tick size to 0.001JPY=1/1000, which is Reciprocal of Trade Multiplier.
