POA--Power of attorney

#1
Is it mandatory to sign the power of attorney form/page, when opening a new account with a broker?

If we want to trade ourselves why this is required-Many problems are arising
by signing this form/page.

Comments , please.

Still if you want you can also not sign it but then if you trade high you will have to sign DIS before placing sell/buy order with broker as without it your broker will not execute you order because he is not authorised to do so.. That also means you cant trade from your home using ODIN etc. You have to be at broker's place, sign and hand him over the DIS and then only your order will be executed..
Hope it was helpful...
