You can control the count or the number of orders you only want to open on a particular Slave. Additionally, you can select a parameter on where you'd like to base the counts. If the number of open or pending orders copied exceeds the value you entered on the following options, it'll prevent the Slave account from copying new open orders no matter the trade direction (buy or sell). This means both buy and sell orders are considered in the count. 

Here are the options you can choose from. Please note that if you combine these options altogether, the most restrictive value will apply.

A.) Max Account Open Position Count (Slave)
Max Account Open Ppsition Count is based on the Slave account's open and pending orders. For example, if you set the value to 10, and you already have 9 open and pending positions, the Trade Copier will allow 1 more open order to go through then it'll stop copying new orders. This means you have to close orders in order to copy new ones to respect the Max Account Open Position Count.
It'll consider all the open and pending orders of your Slave account, from any source, not just those created by the Trade Copier.

B.) Max Symbol Open Position Count (Slave Symbol)
Max Symbol Open Position Count is based on the symbol count of the Slave's open and pending orders. This means if you entered a value of 5, you cannot have more than 5 open and pending orders of the same symbol. For example, if you already have 5 EURUSD and 3 XAUUSD open orders, the Trade Copier will prevent EURUSD from getting copied, while it'll still allow 2 open orders of XAUUSD.
It'll consider all the open and pending orders of your Slave account, from any source, not just those created by the Trade Copier.

C.) Max Account Open Position Count per Master
Max Account Open Position Count per Master is based on a particular Master's open and pending count. If the number of open or pending orders copied from this specific Master account to the Slave account would exceed this value, it prevents the Trade Copier from copying new open orders.
This option is most useful if you have multiple Master Accounts. It doesn't consider orders coming from other Masters, other sources, and orders placed directly on the Slave account.

D.) Max Symbol Open Position Count per Master
Max Symbol Open Position Count per Master is based on the symbol count of the Master account. If the number of open or pending orders copied from this specific Master account to the Slave account exceeds this value per symbol, it prevents the Trade Copier from copying new open orders.
It doesn't consider orders coming from other Masters, other sources, and orders placed directly on the Slave account.
