I think we should be able to share this. Will speak to our team. @siva-reddy can you add it on your list of things to do.
This 25% and over number seems ridiculously high though. Reading the original article, don’t see how is this calculated (is it per day/month/year, amount of profits/losses etc). Let me know if you find that detail.
Btw CFD markets don’t have any overhanging issues like us, no taxes on a trade (apart from brokerage commissions) and almost unlimited amounts of liquidity (no impact cost).
As Zerodha we collect and pay more than Rs 3.5 crores as STT, Exchange charges, GST, Stamp, etc daily. That means in a year over Rs 700 crores. Liquidity in contracts outside Nifty and Bank nifty is really less. We had done an experiment where we figured that conservatively traders lose almost as much in impact cost additionally to the taxes. So over Rs 1500 crores, just from clients at Zerodha. Unless the other charges come down, impact cost is going to keep increasing over time, assuming product suitability framework does come up sometime reducing retail volumes.
So net off charges, the number of profitable vs losing traders in a yearly period, I think in India will be not more than 1 to 2%.
