What is the term"follow orders",which means placing orders with traders(professionals with trading experience/market analysis)and setting stop loss risk controls to avoid losses as much as possible;The tracking system has gradually become one of the standard configurations for contract trading,and contracts are a trading system that can buy up or down based on market conditions,operate in both directions,and can also enter and exit at any time,avoiding risks to a certain extent;The tracking system can assist investors in stopping one-to-many,forward and reverse tracking,automatically completing position tracking,automatically completing net position tracking,and controlling risk of tracking accounts and total positions.
Functions of contract quantification strategy tracking system:
1.When traders settle in,users apply to become platform traders to carry orders,providing them with some revenue sharing,which can bring good contract direction to platform users while making profits;
2.Social functions,with social functions,allow users to freely post,chat,and other operations,thereby increasing the user viscosity of the platform;
3.Market docking,which allows traders and users to choose between multiple mainstream exchanges;
4.Recommendation mechanism,inviting people to settle on the platform,bringing greater benefits;
5.The tracking community can check the trading history of traders(recent profit and loss ratio,accuracy rate,etc.)to better select tracking traders,thereby
常见跟单分自动跟单和手动跟单，自动跟单可以选择要跟的币种，下单的手数，和杠杆倍数；手动跟单需要选择跟单资产跟的价格止盈止损，下单手数和杠杆倍数；
