I had a rare trade on the US markets tonight. I just traded the 10 mins before the off in the Preakness and managed to make a reasonable profit. The market was a bit slow and the volume traded was probably inline with an evening race in the UK. Normally the US markets are very low in volume so I don't bother although I know some traders do trade them.
The Preakness Stakes is the second leg of the American Triple crown. One thing worth noting is that the market is not offered in-play like the UK markets.
I will update progress soon but off to bed now.
