Funny how they (or TCS) mucked up the new interface transition. For a week, customer support at Kolkata was not available on the phone with "all our people are busy". Eventually had to resort to using chat.
Adding a stop-loss order is non-intuitive. In the order type, the only options are Market and Limit. For stops, you have to place a limit order with both the limit and trigger price filled in.
Also, pre-market orders stopped working prior to 9 am.
Under Firefox, that they claim is supported, the entire buy/sell window is not visible unless you reduce the font size.
All said and suffered, the new interface is certainly faster and smoother as they claimed.
