Nikkei225 futures. SGX or CME?

I would like to trade yen-based Nikkei225 futures but I am new to it. I am using Interactive Brokers.

I am confused over which Nikkei225 futures contract to trade. CME or SGX? What are the pros and cons? Which Nikkei225 futures contract do the elite traders here trade?

 

Does Nikkei225 still have a (lunch) trading break. That is what always put me off trading it in the past.

 

No lunch break.
But for Japan stock market, there is lunch break.

 

CME and SGX have NK225 in yen based and USD based.

USD based tends to have lower volume.

CME nk225 yen based and sgx nk225 yen based volume are rather decent.

 

I prefer the yen-based Nikkei225 futures contract. Both CME and SGX look similar. Which one would you trade, if you have to choose either one?
