Programming of external filter for FXBlue copier/reciever mq4/mq5 to control ignoring new trades...

You can make your own modifications to the copier using MQL code libraries in MT4/5.

Before describing the libraries, there are two important notes about re-installing the copier if you use these external filters:

If you re-run the copier's installer program, this will overwrite any changes which you have made to the custom code libraries described below. If you make changes, you should keep copies of your modified files, and re-install them into MT4/5 after you re-run the copier's setup program.

In future versions of the copier, there may be additions to the functions/hooks in the external filter libraries. When a new version of the copier is released, you may need to update your modified code with new functions which the copier expects to find in the external MQL library.

The copier has MQL code libraries called CopierSenderFilter and CopierReceiverFilter. These are used by the copier if you turn on the UseExternalFilters setting in the Advanced section of the sender and receiver options. You can modify and recompile these libraries to create your own rules for the following:

Prevent the sender copying specific trades

Prevent the receiver copying specific signals from the sender

Change how the receiver copies a trade from the sender - override the lot-sizing, swap the trade direction, change the s/l or t/p, or even change one symbol to another

Prevent trade closes in the receiver

For information on how the filters work, simply open the .mq4/.mq5 files in MT4/5's MQL\Libraries directory. You can add your own rules to these files, recompile the .ex4/.ex5 library, turn on UseExternalFilters, and then reload the copier. Please remember to take a backup of your modified files - as described above.
