This Trump ban on European return travel should have us base out and head higher. This should be a positive for the market. Long term buy signal from last week still en vogue.
I don't know what kind of volume analysis you use to determine "a bottom is formed on volume", (depends on TF I suppose) especially in the early overnight session when volume is thin, but I do agree, looking at, or even better, using volume to determine the end of one leg and the beginning of a retrace is the way to go!! A factor to make volume analysis more interesting... rollover, at least technically, started with this overnight session!
Is it me or the market sell off whenever Trump tries to do anything? Wow, let's go to 2400. Stone throw a way.
