now you posted the question in the right sense..Before you posted by giving two brokerage houses name and asked which is genuine.Which means you try to convey a message to readers that one is genuine and other is cheating..You can ask the same query with out mentioning the name of any brokerage houses, as you know very well that mudraa is not a place to give advt or promote any brokerage houses..
now other levies on transaction depend on what all services you asked for i guess, like contract note you can ask for email intead of physical so the postal charges for sending the contrate notes can be saved.
some states charges service tax , some state not.So it depend on which state you open your trading account.
hope it is clear.
you can even send this query to the respective brokerage houses for clarification..If you didnt get a satisfactory answer.
