It is a telling sign of how much market resistance there is for mortgage rates to move lower than current levels when the Dow is down almost 300 points and the market for mortgage backed securities issued by Fannie and Freddie has barely moved.  Typically one would expect some improvement in rates from this steep of a daily drop in the Dow.  The Federal Reserve has been in the market purchasing US Treasury notes which has caused minor improvement in the 10 year Treasury note prices today.  In economic news, the major report on this week's schedule will be the March non farm payroll report released on Friday.  Investors are already expecting another 650,000 job losses in March and an unemployment rate of 8.5%.
