The previous version of the api has a server side limit of 5 orders/second for order placement and 3 order/second to close orders. This restriction is also enforced per ip and app. I remember reading somewhere that with the new enhanced version of the api the limit will be somewhat relaxed.
Personally would be more interested in faster access to close a bunch of orders in case market direction changes abruptly.
Could you please throw some light on this? @Kailash@vivek
This the current API rate limits, we may revise this once we complete migration.
