Copier mode was designed for traders working with multiple accounts simultaneously, money managers, etc. If you know the passwords to the slave accounts, this type is suitable for you. For Copier mode you can and should add all information about slave accounts, included: account number, trader password, copying parameters (lot scaling, symbol's type, filters) on your side. Program have only one part and should be installed only on master side.
Provider mode was designed for Forex signals sellers. Also this mode well suited for money management, if your customers do not want to provide you with trader password. Program is consist from two parts. First part should be installed on your side (master part) and you should enter account numbers only for all slave accounts. You can add, delete, block unblock any slave account any time. Second part (slave part) should be installed on remote (your customer's) computer and your customer should enter password and copying parameters.
You should start master mode on your side to add master and slave accounts and specify copying settings for these accounts if necessary. Software is working in master mode only on one computer on which it was originally installed and started (it is mapped to the hardware of this computer).
Then your clients should start software in the slave mode. In fact they start the same software but when it starts up from different computer from yours it automatically works in slave mode (when they start software on their computer, software defines that this is another computer from the one where master part should work and thus software works in the slave mode)..
In this slave mode user (your client) can specify password for his slave account(s) and accept trading signals.
Note. Once trading password for slave account was specified on the side of your client both master and slave part of software can connect to this account and transfer trading signals to this slave account. So it is possible that your client is already working with his instance of software when you start up your (master) part and in this case both parts of software are connected to the slave account(s). That is why it is necessary to have only one instance of software working with each account to avoid collisions and orders duplications. Software informs you about double connections to single account during startup and allows to block this account to disallow sending trading signals to this account from this instance of PowerTradeCopier.
Once you have all master and slave accounts specified you should group slave accounts by assigning the client passwords to these accounts (this can be done by means of "Set passw for client" button in "Slaves" tab). Several slave accounts with the same client password make a set of accounts of a single client. You should tell this password to your client and then client should enter this password in his instance of software in "Setting" window by means of "Set password" button. Then your client will see on his side only this set of slave accounts and work with them only. If no client passwords were specified for some slave accounts these accounts would be displayed on the slave part which was started without client password entered in the "Setting" window.
Note. Master part of PowerTradeCopier displays all slave accounts irregardless of the clients passwords specified for them but transfers orders only to the accounts for which the same client password was specified with the one which was set in "Settings" window of the master instance of software. Slave accounts that receive trading signals from this instance of PowerTradeCopier have status "Working" in the "Copier" tab, slave accounts that has another client password and thus do not receive trading signals from this instance of PowerTradeCopier have status "Working. Block passw" in the "Copier" tab.
