A real-time component interface is available for PC-SPAN version 4. With this additional software module, licensed separately as SPAN Real-Time Component Interface (SPAN RTCI), you can develop programs which interface to PC-SPAN in real-time.

For example, suppose a customer requests an order. Using the component interface, your program can call PC-SPAN, specify the updated position that will result from the order, request that the performance bond be calculated, and receive back the updated performance bond requirement--all with extremely rapid execution times.

The SPAN Risk Manager Clearing software also has a real-time component interface. With this software module, in addition to everything you can do with the component interface to PC-SPAN, you can develop programs which execute the functions of the SPAN Risk Manager Clearing in real-time.

For example, you could programmatically update market prices for futures and physicals, and then recalculate volatilities, theoretical prices and risk arrays.

This topic provides a technical reference to the real-time component interfaces for PC-SPAN, SPAN Risk Manager, and SPAN Risk Manager Clearing.

Below is an example of calling the component interface from Visual C++ code.

#include <stdio.h>
#include <ole2.h>
#import "C:\Span4\Bin\SpanCom.tlb" no_namespace, named_guids

int main(int argc, char* argv[])
{

if(FAILED(::CoInitialize(NULL))) return 1;

        ISpanCom* pSpanCom;
        if(SUCCEEDED(::CoCreateInstance(CLSID_SpanCom, NULL, CLSCTX_LOCAL_SERVER,
        __uuidof(ISpanCom), (LPVOID*) &pSpanCom)))
        {
                    printf( "Success\n");
                    // pSpanCom->Load("C:\\cme0216s.par",1,0);
                    pSpanCom->Release();
        }

        else printf("Fail\n");
        ::CoUninitialize();
        return 0;
}

dispinterface ISpanCom

methods:

short Load(BSTR fileName, boolean replaceExc, boolean useExtLayout);

Description:

Load any SPAN recognized file into PC-SPAN, including SPAN files (*.SPN), classic "flat-files" (*.PA2), position files (*.txt and *.pos), etc. All position files (*.txt and *.pos) require corresponding risk parameter files to be already loaded. Positions are loaded into the currently selected point in time. If this point in time is not present positions are loaded into the first available point in time.

For more details on supported file formats, click here.

Parameters:

fileName - BSTR - The document to be loaded.
replaceExc - bool - Specifies whether PC-SPAN should replace already loaded exchange complexes with the ones from the file (true) or leave them intact (false)
useExtLayout - bool - Specifies whether PC-SPAN should use extended file layout when loading positions. It is only used for loading old format position files (*.txt).

Return Value:

short - Return value can be 0 (success) or non-zero (failure).

short Save(BSTR fileName);

Description:

Saves all the information from PC-SPAN into a file.

short SelectPIT(BSTR busDate, short isSettle, short isFinal, BSTR busTime, BSTR description);

Description:

Selects a specified point in time as current point in time. Once selected, a point in time remains selected until it is reset, a different point in time is selected, or until the point in time is cleared.

Parameters:

busDate - BSTR - The date of the point in time to select. The point in time must be in a "YYYYMMDD" format. Alternatively, the busDate string parameter may be empty to select the first point in time.
isSettle - short - Search for a point in time where the settlement is: '0' for non-settlement; '1' for settlement; or '-1' for no preference on settlement indication.
isFinal - short - Search for a point in time where the final flag is: '0' for not final; '1' for final; or '-1' for no preference on final indication.
busTime - BSTR - When the isSettle flag is 0, the busTime may be optionally specified. It is formatted as "HHMM". If isSettle flag is not 0, the busTime is ignored.
description - BSTR - When the isSettle flag is not -1, the description may be optionally specified to match the description of available points in time. If passed as an empty string, it is ignored.

Remarks:

If busDate is empty and the isSettle is -1, the rest of the parameters are ignored and first available point in time is selected. If either isSettle or isFinal is set to –1 this parameter and all parameters following it are ignored. If busTime or description is empty it is ignored.
