Don't do the "all or none" when You try to SELL a thinly traded company with a small float.

I tried it both ways and the "NO RULE" worked better in that instance.

See, If Your investment House gets 4 trades to sell Your stock, then that encourages them to dump your's first.

Commission.

They make money and You make money.

Win, win situation

I do know how to day trade, but refuse to do it.

Usually it Kicks my A$$

So, I seldom do it.

Maybe once a year?


Note:
If You are good at it and makin da' money then go for it.

Good Luck in Your investments
