Hi,
I have a web page and it displays live odds. I am getting data from sql server. I want to display up/down arrows according to the increase/decrease of the odds. So I wonder if there is a way to keep the previous data? Let say, at first the odd is X. Then after sometime odd becomes Y. So I need to keep X to decide if there is an increase or decrease. Then after some time odd becomes W. So this time I need to store Y so make the same calculation. Any smart idea to accomplish this?
Best Regards.
