Need feedback on 5Paisa/IIFL/Kotak Deep OTM option Sell

Hi All,

Any experienced trader here could please give specific feedback on 5Paisa or IIFL or Kotak securities broker Deep OTM option Sell capability ? I have cash and not looking for margin reduction but reliable trade execution at right/best price.
For e.g. I want to sell Nifty 18500 CE and 20150 PE when Nifty Spot is 19600. Even I am ready to use Nest Trading platform, my point is about Hard Financial numbers not about smooth UI written in html5.
