@keer2405 In post market, you won't be able to see prices as the market will be closed and you will receive some junk data only. If you are testing your API after the post market, you can test that on commodity market as it is open till late night.
Hi @keer2405 we don't have any limitation to subscribe symbols. Also you need to convert tick data to candle data based on your requirement or you can use the historical data API to get the data.
HI @prateekjjw001@daytrader@keer2405 Thank you for brining this to our notice. We were in the process of updating the certificate and rolled it back due to this error yesterday.
