My stocks are under CDP holdings. Both my online and offline accounts are linked with the CDP account. Technically I can use any of the accounts to sell those stocks. My request to him was to use my off line account to sell my stocks. Moreover my online account also under him, so he can see the stock movement in that.

My broker's claim was  that "the platform you use to buy , the platform you must use to sell. When I pointed to him that I sold a stock through online account which was bought by him. He immediately checked and informed me that there may some error so that I was able to sell it.

I am aware that his intentions are not correct.

Any way today I requested my brokerage firm to change the broker. If necessary I may open account in another security firm.

Thanks for your valuable comment.

That was a frustrating situation!  

Just wondering: 

Maybe can post a general question to that brokerage firm, whether a broker can also help a client sell stocks that was purchased via online acct.  That way, minimise any misunderstanding. 

I agree with you...i am using poems platform..they given a good service so far....

You can see a good and bad employee in every working place. It is not advisable to rate an employer with one employee's behavior. As such i am not going to name the brokerage firm. A simple solution is to get rid of him. There are aplenty to serve us.

Thanks for sharing your comment. 

I have no details of the policies of other brokerage firms, but with mine, my account is still under the management of my broker.  The only difference where my account is concerned is that, its cheaper for me buy/sell online.

But I'm sure it's still possible to have your broker buy/sell your stocks, particularly if you are out of Singapore and unable to find an internet connection to transact.
