Which brokerage?

Hi guys,

Can you help me identify a brokerage that has

-> php api -> margin trading -> zero brokerage

For NSE. I have a script hosted on my server and Linked to Zerodhas kite api.. the execution cost is eating my profits.

I've been trying over the past 2 weeks to identify one broker who offers all these 3. They claim zero brokerage but for intraday they add the execution cost on both buy & sell side.

Almost 50% of my profits are taken by them.

Any leads?
