Second Resolution Packages

QuantQuote second resolution stock data provides a high resolution view of intraday activity while requiring much less computing power than tick data.

QuantQuote second resolution data files are available for all NASDAQ and NYSE listed stocks starting from January 1998 to the present. The dataset is research ready and contains splits and dividend adjustments, and accounts for symbol changes and survivorship bias.

Historical second resolution intraday stock datasets can be stored in compressed binaries created by our QuantEDGE software. This innovative software allows our datasets to take up to 92% less space versus uncompressed datasets. QuantEDGE libraries can be easily implemented into any C++ testing/trading code or used with the included standalone application that decompresses data files on demand. Second data is also avaliable in CSV format.

A full data description and specification can be found in our second resolution data whitepaper.

All QuantQuote second resolution intraday stock data come in the QuantEDGE advanced compression format. C++ QuantEDGE libraries perform on-the-fly decompression in memory and automatic data loading in a single step for unparalleled performance and ease of use. QuantEDGE is also fully integrated and compatible with TickMAP.

QuantEDGE allows for a 92% reduction in data file size, greatly reducing storage requirements. The binary format combined with decompression in memory actually makes the loading of QuantEDGE format data faster than loading uncompressed text data despite the added processing time from decompression. The libraries are platform independent and can be run on most Unix/Linux/OSX systems. QuantEDGE has also been used successfully on Windows1.

A standalone QuantEDGE application is also available to automatically decompress second resolution data files. For a full description of QuantEDGE and its capabilities, please see our QuantEDGE Whitepaper

1 Windows usage is not fully supported, but QuantEDGE has been successfully deployed on Windows by many customers.
