The “Order Filters” lets you filter symbols to be copied between your Master and Slave account.
You can create either a “Whitelist” or a “Blacklist” of symbols and you can define it for all masters or for each master separately.
A whitelist is a list of symbols that are granted to copy. When a whitelist is used, all symbols are denied, except those included in the whitelist. The opposite of a whitelist is a blacklist, which allows copying from all symbols, except those included in the list.
To configure the “Order Filters”, just go in “Slaves” -> “Accounts”, and click on little “filter” button for the slave of your choice. Once the popup opens, you can select if you want to create a whitelist or a blacklist, then select if you want to apply it to all masters or only for a specific one, and finally enter the list of symbols by clicking on the “+” green button. You can remove a symbol clicking on the “-“ red button next to symbol.
