If you need to pass pointers around between your script objects. I found that wrapping boost::any in a simple object with a templated get member function seems to work well and keep things relatively type-safe. Let me know if you are interested and I'll post the code here...

AngelScript arrays are not compatible with C++ arrays, since AngelScript needs to do bounds-checking, etc.
If you want to be able to pass arrays between C++ and AngelScript, you'll have to override AngelScripts built-in array type with a type that both AngelScript and C++ can understand.
As Rain Dog said, you can do this by registering the std::vector implementation, using Deyja's code. That code is available in the AngelScript zip file, under /tests/test_feature/source/stdvector.h.

PS. I'm not sure if I'd like to let a computer program do my stock exchange business' for me [wink], but even so it is an interesting project you have going there.
class CPtr{public: CPtr() { } CPtr(boost::any &myany): m_ptr(myany) { } CPtr &operator=( const CPtr &rhs ) { this->m_ptr = rhs.m_ptr; return *this; } template<typename T> T get( void ) { T pRet = NULL; try { pRet = boost::any_cast < T > ( m_ptr ); } catch (const boost::bad_any_cast &) { pRet = NULL; } return pRet; } static void RegisterPtr( asIScriptEngine *as ) { int err = as->RegisterObjectType("Ptr",sizeof(CPtr),asOBJ_CLASS | asOBJ_CLASS_CONSTRUCTOR ); assert( r >= 0 ); err = as->RegisterObjectBehaviour("Ptr", asBEHAVE_CONSTRUCT, "void CTor()", asFUNCTIONPR(Constructor, (CPtr*), void), asCALL_CDECL_OBJLAST);assert( r >= 0 ); err = as->RegisterObjectBehaviour("Ptr", asBEHAVE_ASSIGNMENT, "Ptr &f(const Ptr &in)",asMETHODPR(CPtr, operator =, (const CPtr&), CPtr&), asCALL_THISCALL);assert( r >= 0 ); }private: boost::any m_ptr;};// If you passing this back and forth to an object // you might have a script object like thisclass CMyScriptObj{ public: static void RegisterMyObj( asIScriptEngine *as ) { int r = engine->RegisterObjectMethod("MyScriptObject", "int setPtr(Ptr &in)", asMETHOD(CMyScriptObj,setPtr), asCALL_THISCALL); assert(r >= 0); r = engine->RegisterObjectMethod("MyScriptObject", "Ptr getPtr()", asMETHOD(CMyScriptObj,getPtr), asCALL_THISCALL); assert(r >= 0); } CPtr gePtr( void ) { return CPtr(boost::any(m_pObj)); } void setPtr( CPtr &ptrObj ) { CMyScriptObj* pMyObj = ptrObj.get<CMyScriptObj*>(); if(pMyObj) m_pObj = pMyObj; } private: CMyScriptObj* m_pObj;}// To use this in ASMyScriptObject object();Ptr ptr = object.getPtr();object.setPtr( ptr );
