T/A is a tool and is still useful even for fundamental investors - charting will rarely get you in at the bottom or out at the top when it does it’s a fluke - any chartist on hot copper who says they consistently pick tops or bottoms is speaking da bullshize
The aim of T/ A is to capture the bulk of the trend , to stay in as long as possible in the uptrends letting the winners run with trailing profit stops and to get you out as early as possible to preserve capital in the down trends
