======================Welcome to ET.
Buying breakouts is a pretty decent strategy in a raging bull market. It can be frustrating when the market is in a range or backing and filling. As you've noticed, people who are already long the stock often use a new high as a place to lock in some profits.
Trying to pick bottoms can also be dangerous, as what looks beaten down often gets beaten down even more.
If it was easy, everyone would make a lot of money, but few do. My advice is whatever you do, be disciplined and don't let any one trade go too far in the red.

''WELL, its a bull market you know'' That's what ''old turkey'' said when ever someone would try to get him to sell his longs in a bull market,LOL

Actually I like a good bull market/ Up-trend ;;;;;
+ good bear market/downtrend
Frankly,, study SPY on 10year+ charts, 3 year weekly donchian channels.....
Its a very extended, old bull market, + late in the year.
Sure it[bull market] '' could more extended '';;;;; '' its a bull market , you know''
I agree with AAA on this ''not a raging bull market'' SPY took out a monthly low recently, sell volume looks better than buy volume on longer term charts.QQQ has raged recently, but still very old , EXTENDED UP-trend.
Wisdom is profitable to direct;
2001 Traders Almanac[SELL in MAY + go away] + newer editions could help you, realize frankly its a risky, risky bull market, when SPY or any takes out a MONTHLY LOW=look out below.
NOT a prediction;; markets don't work that way.Hope this helps, it helped me
