Alert on sudden change in OI on ATM strike

Hi, is there a way to get alert on a sudden change in OI.
I was looking at Friday charts and could see sudden drop of OI in Puts (~33% drop in a matter of 1 min) around 10:30AM and then sudden increase in OI in Calls.

Is there a way to get alerts on these sudden changes in OI. What are the ways to be able to setup a system which can trigger these alerts.

how do you use the changes/spikes in OI to guage the market sentiment and the strategy to be deployed? What is the logic behind this? Please post it here
