selling shares

I would like to sell my shares, and am being told insufficient security....what should I do

it happens if the shares are 100..n if the profit is small..

okay, have 300 shares ....so I can't sell all of them?

I believe perhaps your shares have not matured

gat2 You have to wait for 3 working days after buying shares. From then you will be able to sell your shares.
