I understand.. lost a lot also by buying and selling to make a little extra profit.

Learned to pick a stock and stay with it.. and let it ride.
For me this only works with junior small cap funds.

For example; if i want 20.000 of one of the ROF partners and i expect it to grow 30% for the next few weeks.. i buy 60.000 pieces, wait until they gained the 30% and i will keep only the shares i wanted in the first place.. (for free) and i can let them ride as long as they need.

Got in Not in December 06 at 0,65 Got gready, sold at 1,74 and had to buy back higher.

Set goals and stick to them
