Evening Jako1,
RXP's bar today I find very interesting. Looks like an upthrust to me.
However, I noticed the course of sales showed minor volume went through towards the end of the day to bring it down from $1 to close at $0.97.
Do we read anything into this? Eg, big buys on the way up, little sells down to end the day?
I don't know much about going into time frames shorter than daily and which one to look at?
