"I guess my main concern is the ALU 1 min chart shows selling down pressure."
That is too granular for a stock trading at a 10-year new high.
A 1-hour chart I sometimes look at for refining entries using 9, 21, and 50 EMA lines. But generally I like to look at longer-time frame charts. Even monthly charts can be useful for filtering out any previous price overhang. Fortunately ALU is trading in blue sky territory.
