instantaneous... no lag... order modifications also reflect very fast...
at first the simplicity of the order interface might make a new user little overwhelmed, however, once acquainted it will become difficult to place orders at other broker terminals...
place orders from charts, option chains, lots of freedom...
several innovative order types available as well...
never seen their core TWS platform 'flapping wings' even on hugely volatile days for past several years...
I am not looking for a fancy platform
Nothing fancy, you'll get all that you need....
Plus, nice inbuilt Option Chain...
Plus, rock solid APIs to build your own things...
Plus, free AB data via built-in plugin...
Plus, IBKR takes responsibility of their actions...
Speaking of demerits:
- If you're a positional or intraday Options seller, margin required is generally 25-30% additional on top of NSE requirements. And no Pledged Margin available either! No Mutual Funds! No Bonds!
- Realtime Volume data is unreliable. Historical is okay!
- No OI data
- No Options pay-off
