@nithin I’ve got a UI/UX suggesstion for the buy/sell window. Allow me to share.
The window blocks the view of price of the scripts towards the bottom. This foreground window should not interfere with the background stock prices.
The total amount investor would pay/ receive for the buy/ sell order should be displayed. For example, in this screenshot, it should display the total cost of 20 Reliance shares at market price all inclusive of brokerage, STT, .etc. so the investor knows whether he has that much margin available or not (it shows right above this window) before placing his order. Similarly with a sell order.
