QLSNUMS.DLL

The QLSNUMS DLL allows list, stack and queue data objects to be shared between and across systems, pages, indicators, paintbars, studies and other programs. The objects can also be easily shared with Visual Basic, C programs, Excel and most languages that support 16 Bit DLLs.

Further features of QLSNUMBS.DLL are:

Enhance Tradestation and SuperCharts programs by adding global container data structures to Easy Language. The DLL provides lists, stacks and queues. These structures are far more flexible than arrays.
Fast Sorting. A fast sorting algorithm is provided that allows you to sort a number of lists of data simultaneously.
Statistical Functions. Calculate mean, median, mode, standard deviation, variance, minimum, maximum, skew and kurtosis on lists.
Use the same code for Historical and Real time systems. Unlike other Global DLLs you can use lists, stacks and queues in both Historical and Real time systems without changing the code.
Strings and Floats. You can store and retrieve floating point or string values in lists, stacks and queues.
Break the 64K size limitation of Tradestation systems. A common problem, when writing large systems, is the error: "EXE CODE TOO LARGE". The DLL gets around this problem by allowing you to cascade Multiple Tradestation systems with each accessing a pool of global container objects.
Work with Multiple time frame systems. Lists, stacks and queues provide a more elegant solution to working with multiple charts than do global variable type DLLs.
Improve data organisation and program design by structuring your data in container objects.
Fast and Unlimited. The system uses a hashing scheme to store data and so lookup is fast. All memory is dynamically allocated and virtually unlimited, the only limits are what windows can supply.
Interfacing. The DLL can be used with any Windows application, not just Tradestation. A Visual Basic and C interface is provided so you can build custom applications linked to Tradestation. With the interface you can do complex calculations or add interfaces to your Tradestation systems.
Use with Hashnums DLL. This DLL can be used with Hashnums DLL to provide an even more sophisticated Easy Language programming environment. Work with Lists, Stacks and Queues of complex structured objects.
Debugging Tool A Visual Basic program is provided with an easy to use windows interface to the DLL. The program can be used to discover what the DLL can do without having to write any code. The program can also be used as a real time debugging tool.
Demo Program. Ask for a copy of the demo package. This is a fully featured demo, only restricted in the number of data points you can store.
