Actually, it's what Leon said.

EasyLanguage is a scripting language used to write trading systems.
TradeStation uses this scripting language.

I'm writing a compiler from EasyLanguage to machine code. What I need
is a DLL that can load into TradeStation or other trading platforms
and exports a function or two. What I want is to make sure the DLL has
just the functions used by the trading system being compiled, to make
the DLL very small and for that additional coolness factor.

I was thinking of SwiftX because, from what I understand, it does not
carry over any extras into the target. I suspect that SwiftX for x86
is just the ticket.

The reason I'm thinking of writing this in Forth is because anything
else would look like a multi-megabyte virtual machine in a DLL that
needs to load the compiled trading system. I suspect this may be more
error-prone than a single small and self-contained DLL.

    Thanks, Joel
