@Mehul,
you have the following basic possibilities:
1. MS Pro has a default DDE Server to communicate with Excel
2. This "third party" library supports also data transfer to Excel:
MetaLib: SDK for reading/writing MetaStock security price data in VB, C#, Delphi, C++
3. programming a MDK DLL extension to the script language you can support this DLL with your signal information and write this in Excel
Item 3 requires programming know how, concerning items 1 and 2 you have to inform you, whether these methods allow not only price data transfer, but transfer of other information (like signals) too!
bye,
