Local Trade Copier EA

The problem: many local trade copiers only filter (if they have them) for symbols, magics, comments on master or slave, not both. Moreover, many local trade copiers change the comment field of the slave trades, and most change the magic number of the slave trades, for tracking and syncing purposes. There are many interesting local trade copiers in the marketplace, but none quite fulfills my need. 

My Need: I’m looking for a lightweight (easy on CPU) MT4 to MT4 local trade copier (open source) that can 1) Filter for Equal/Not Equal symbols, magics, comments -- on both master AND slave; and 2) Preserve, if I so desire, the master’s comment AND magic on the slave trades. I’m not sure if the second request is even possible, in there must be a reason so many local trade copiers change the magic; but I’ve seen at least one do it, so I know it can be done, and I’m looking for creative solutions. Slave accounts should be able to copy both open and new trades of master, not just new trades, as well as being able to re-enter master open trades if closed out on the slave end. I should be able to attach different Master instances with different “channels” (setups) to different charts in the Master terminal, and I should be able to attach different Slave instances to receive these different “channels” (setups) to different charts in the slave terminal.
