Re: When do you attempt to sell and rebuy lower...

Don't ever say "Never" Grin

Trading is a losing game. You sell because you need liquidity to by things you need. You sell because you wish to re-balance your portfolio. You don't sell "to rebuy lower".

Please do not say this as a global assertion just because it applies to you personally and to inexperienced traders. There are actually people who are very effective at trading. Not trading may be what is right.. for you, but not for everyone.

It is different when you are a market maker (only big institutions can be) but other than that it's like people at the casino claiming they have a system. And some people get lucky. That's what keeps the casino going.
