I have been using the historical API to backtest and trade the market using the NIFTY50 1min candles for the last year or so. However since the last week (around when there were issues with the kite charts as well) there has been a few issues -
503 Service Unavailable - No Server is available to handle this request.
When the request does go through, there is a huge delay in the creation of the latest minute candles that ranges from 2min to 20min.
I understand that websockets must be used for real-time data, but my system only requires candles even with a lag upto a few mins. I've tested it thoroughly and was working well for the last year. If nothing, would request some level consistent behaviour from the API's so that systems can be built predictably.
