I have been using Zerodha for just shy of 1 year. I appreciate the brokerage competitiveness your organization has brought in - disruptive market model. Awesome!
However, as a serious trader cum investor, there are certain expectation which I want to bring forth to your attention specially in derivative trading. All these are inspired by looking and experiencing the trading in matured trading platforms (Think-Or-Swim etc.)
Must have a option chain data available in the software (irrespective of pi, kite etc.)
Provision " one click" order from that option chain data
The option chain data must also reflect not only option Greeks, but also IV, IV percentile as well in one go so that a taken trade is an informed one.
Should also have prebuilt strategies, with an option to update/modify them.
I can imagine that this would be an investment of effort and resources and serious traders won’t mind paying additional fees to avail such features.
