Trading the 5th digit with a broker that allows (supports) 5 digit trading such as Zecco. I can buy HFBG in the spread 00031-00039. When a trade like this goes through you don't see it on L2 because it only sees 4 digits and likewise the trade tool only sees 4 digits so when I buy @ 00035 the trade will print as a 0003 because it doesn't round up either....in addition the trade tool shows the trade as a sell (0003) when in fact it was (00035) trade in the spread.
