Just want to say thanks for bringing this up... I was unaware of the mini contract. I've been papertrading the SGXNK contract the past few weeks, and I really love how it moves so orderly, much like the ES, probably due to such a high tick size (5 points). It's nice to know I can jump in with much less capital at risk with the mini. I guess the disadvantages are an additional data subscription through IB, a higher comission to tick ratio than the SGX contract, and slightly shorter trading hours (less pre/post market time vs. cash index). But if you have an edge and the discipline to trade it, you should still be profitable, and you can work your way up to the big contract. Thanks again!
