In this part of the documentation, you will find important attributes related to your position size, leverage, and calculation regards to your balance.
In the volume section, you can set your desired leverage with a slider or typing the value.
The initial margin is the amount of money that you need in order to open a buy or sell-on position. Considering the example from the screenshot: You can buy 1,000 USDT with an initial margin of 100 USDT(with 10x Leverage) while your initial position size is 1% of your available balance.
You can set your margin/Initial margin via slider or typing in numbers on the set margin part or you can also type your initial margin in terms of the percentage of your available balance.
You can set your position size in the same way you set your initial margin.
You can set the target icons in the volume part.
For instance, when you set your target as the initial margin, it chooses the initial margin and position size as a main method of calculation. That means the entered value of your initial margin value will stay locked even though your available balance changes while you are waiting for your position to be filled.
The values without the target icon are only approximations at the time. The values can change.
For Manual Trading, the approximations can be quite close to actual values considering that you open your position immediately rather than waiting for entry conditions to be met.
For Smart Trading, the approximations can vary from the actual values when your position is opened. This is mainly because the smart position has entry and exit conditions. Your entry conditions can take time to be met which could result in the difference between the approximations and the values when your position is opened.
