Martin spi opens at 9.50 not just cmc .
CMC prices are based on spi and or xjo depending on which one u trade .
The problem with trading the aussie 200 [xjo] is they will often make adjustments to it depending on the deviation to the spi
Very very occasionally they may screw up and allow a trade based on a frozen price but I've only seen it once or twice on cmc .
