Well as far as I am concerned I have developed my edge from years of trading arbitrage in the treasury market and trading outright in the equity futures markets. This has given me my edge in trading outrights not only in the treasury market but other markets as well. Recognizing what the people who move the market use and know how to interpret what they appear to be doing is key to my edge. Watching the yield curve move in real time in the cash markets is very important.
