For Copy Trade settings, the「Automatic」way to calculate the size of orders is added.
[Fixed] and [Leverage] require the user to actively enter the amount of a single order. However, after selecting [Automatic] mode, the system will calculate for followers' positions automatically based on a certain ratio when the trader opens a position. The ratio is the trader's assets and the follower's assets in Copy Trading account. The [Auto] mode allows the users to follow the trader's strategy exactly at the level of fund as well.
If trader A has a balance of 1,000 USDT in the copy account, trader A uses 100 USDT with 5 times leverage to long BTCUSDT. If a follower invests 500 USDT, the follower's opening ratio is 500/1000=0.5. It means the follower long 0.5*100=50 USDT BTCUSDT with 5 times leverage.
Advantage: The position of the follower and the trader are similar, that is to say, the risk of the position is basically the same. This mechanism lets the risk of follower's positions stay at a relatively lower level. In the long run, traders can better help followers in risk control and income management.
