You divide the budget allocated to your strategy by the number of concurrent positions you choose and determine the size of the positions to be opened.

Let's assume that your robot budget is 1000 USDT as in the example in the image. When you set the number of concurrent positions to 5, the amount per position will be 200 USDT.

When determining the position size, it is important to make sure that it is in line with your balance in your exchange account. If your balance is less than the amount of positions to be opened, your robot will not open a position.

For example, let's say the available balance in your exchange account is 100 USDT. In the budget settings of your strategy in Traderlands, the amount per position should be below 100 USDT.

You should also make sure that the position size does not fall under the lower trading limits set by the exchange. If the position size is less than the minimum trade amount set by the exchange, your robot will not open a position.

For these reasons, when setting the position size, you should make sure that it is compatible with your balance and that it complies with the exchange's lower trading limits.
