Getting data feeds from multiple brokers

Hello. I want to be able to pull in datafeeds from different brokers into 1 instance of Metatrader.

I have read there's a way to do it via DDE. But I'm just wondering if anyone else has any cleaner suggestion than using DDE. Thanks.

1. DDE.? It would have to be a customized DDE, like Pipes or Mailslots (see posts by me and sangmane on how to do IPC - (Inter Process Communication).
2. Offline charts - have secondary MT4s collect the data and write it to the hst file of the master MT4.

file mapping (shared memory) discussed in this thread:

Can't be done with DDE, as each instance of Terminal.exe uses the same DDE name so can't tell which broker the signal comes from.

Easiest way is to map all of the "Expert" folders to a common virtual directory. Even use a RAM disk for this for added speed.

The MQL to write/read files in the now common "Files" folder.

Not hard to do, but you need to know what you're doing.

I write date from several brokers to an in-memory database called FastDB.
