@sujith I have been using postbacks. I found that order updates coming from ticker also has similar data. So are they same? Will I get anything extra in order updates? Where should I use postbacks and where should I use order updates?
Both will have same data but these are just different channels. If you don't have a server then it will be difficult to use postbacks in that case you can use websockets to get order updates. It is up to users, they can choose anything.
