10 Year Treasury / Mortgage rates consolidating before rising

If you are contemplating whether to lock a mortgage interest rate, consider the chart here. It appears to be knocking repeatedly on the 3% door and will eventually break through and rates will rise. Even if the consolidation dips to the C point, that may not be enough to trigger a rate decrease, but if so, lock it as it will quickly disappear as the rate goes back to D, then a breif dip to E before taking off into the 3% Plus land.
