Trading system UI refresh issue
I am new in the trading domain, and developing desktop trading system. Here we have to update the live data in grid. Since quotes can be changed with any number of time in a second. Does there is any standard design to address this issue? Which and how much trade should be update per second

This is your decision, there is no standard for this.
It depends highly on your programming skills and the features to be implemeted in the grid. For instance change of background colors or arrows at change/up/down og fading of the same in the cell.
Those features can be quite CPU expensive in the client application.
How is the data being used, for visual display only or in algos. If it is algo’s then all the data. For visual display, develop a combination of time and size. Set a default time say .5 second or 1 second, if quote size changes by x amount bid and ask and is less than default time then update. If quote price changes that is an automatic update.
