I had posted a thread about this issue in the morning but seems that some angry moderator has deleted it. So I am posting again.
The /holdings API used to return close_price as last session's close price. This is useful in calculated today's PnL and PnL percentage. Since this weekend the API returns this field value as 0. I spent good time this morning in figuring out why the PnL is all infinity (good feeling!) this morning.
Workaround is to call /quotes API to get last close price but this was working for a long time so I do not want to do patching there.
Is this going to get fixed? Also do not delete the thread without intimating the customer.
