Sorry GF, I somehow missed your post.
No, I almost never buy the high volume downbar.

It really depends on the time frame you intend to hold it for, and what the trade is intended to do.
There are many ways to tackle this type of potential set up.
For me as mostly a swing trader, I just make a note that sort of high volume bar downbar, and prefer to wait and enter on low volume downbars (preferably as price comes back within the body of that bar), after that sort of high volume is seen.........or even better on a breakout, or test of the breakout, of a trading range/accumulation zone (which would be roughly 22.5 / 23.5cps by the looks)
