I am using get_pricing() to get intraday quotes, and I notice that this is the performance bottleneck in my code. I am interested in getting the price at a specific time of day, eg: 2:30 PM EST. I am currently using get_pricing(..., frequency='minute', ...) to get all 390 intraday prices per day, then using at_time('14:30') to filter down to the single price I'm interested in. In the interest of improving performance, is there a way to retrieve just the '14:30' quote each day using get_pricing()?
