"Classic Trading Volume Mnemonics"
Buy horizontal, buy dips, don’t buy vertical; the selling point is at the boiling point.
Continuous small rises are real rises, while continuous large rises signal to exit.
A sudden drop with low volume is intimidation; a gradual drop with high volume means you should withdraw quickly.
A significant rise requires a pullback; don't dig deep holes and don't buy too much.
