Also would like to bring to your notice a hidden cost called turn over cost.
its 0.05% of the turnover amount... ( rate * number of units applicable for either in buy or sale trades ).. so more the number of trades, more will be the turn over... if you have 400 odd trades. Turn over would take a good chunk.
eg. with 50k corpus, u r buying 1000 units for Rs 50 and attempt to sell at 50.5 and do this say 400 times
your turn over would:
100k * 400 = 4 crore.... making transaction cost of Rs. 20,000. Brokerage is apart from this cost!
keep this in mind....
