get the following formula to work and am definitelyin over my head on this
one. I am trying to accomplish the following:1. Set the Time frame to daily
and get yesterday's close(vxdc)2. Set the Time Frame to one minute and get
the most recent close(vxmc)3. Subtract vxmc from vxdc for vxdif4.
Use vxdif for plot and colorI appreciate any help that can be provided on
