Kotak V/s Angel DP charges, kindly help

I opened an account with Angel and its charging me 3 paise and 30 paise. I also wanted to test Kotak so opened an account with it.

In the welcome kit from Kotak Securities, i on a paper see

Market Transactions (Sell ) 0.04 % of value of securities or Minimum charge of Rs 22/- (for sell transactions)

and

OFF market transactions (Sell) 0.04 % of value of securities or Minimum charge of Rs 22/- (for sell transactions)

When i Purchase and sell from Angels trading account i see only brokerage, Service and STT. Never Saw DP.

Know kindly help me i am confused. How and from where this dp came in and will this affect my normal trading activity.
