I've traded the
SGX Nikkei way back when.
If not much has changed, that contract is fairly thin compared to US index futures and it may be electronically traded only, before it was side-by-side with the pit contract.
For one thing, Asian markets have way more 100-200 range days then US markets.
If you can stomach those swings, its a good market to trade.
This is the famous market in which Nick Leeson bankrupted Bearings Bank. I think thats how you spell his name.
