I want to create a KDB table with an array: - for a regular one, I would have t:([]time:`time$();price:`float$()); for each time, there is only price - I want to have a table with a price array for each time. should I create it using t:([]time:`time$...
when I query HDB, it is always faster using date>$date$? $date$ could be .z.d-10000, which is much larger than my earliest date in KDB.
1. how to push data to KDB using qpython? 2. is there any script to push data to HDB? assume I have lots of dated trade data, how can I push data to kdb by setting trade date as the data of HDB. thanks
