Well, first of all I'm expressing a hope that SFE will launch one soon.
I'm a brilliant paper trader but a real suck-**** actual SPI trader - the reason is that $25 per tick scares the halloweens out of me! I'm over-sensitive to even small losses.
So, if there were a MINI SPI with $5 per tick I think I could quit my day job.
Or on the other hand, is there anything else I can trade based on the SPI that won't have me smashing my furniture should a ten-tick loss occur?
