Asynchronous collector objects

A computer-implemented method, comprising:

• generating, by at least one data processor, a first instance of a collector object, the first instance of the collector object generated for a first time period having a first length, and the collector object being configured to collect values over time periods having the first length;
• updating, based at least on one or more values from a first record, the first instance of the collector object, the first record storing values collected over a second time period having a second length;
• and
• performing, based at least on the first instance of the collector object, a valuation operation, the performance of the valuation operation requiring values spanning at least one time period having the first length.

A non-transitory computer readable medium storing instructions, which when executed by at least one data processor, result in operations comprising:

• generating, for a first time period having a first length, a first instance of a collector object, the collector object being configured to collect values over time periods having the first length;
• updating, based at least on one or more values from a first record, the first instance of the collector object, the first record storing values collected over a second time period having a second length;
• and
• performing, based at least on the first instance of the collector object, a valuation operation, the performance of the valuation operation requiring values spanning at least one time period having the first length.
