Latest situation, I just tried it and found that if you set this quick take profit and stop loss, it actually takes the order.

Let's calculate the cost and recovery time for everyone. Suppose two accounts each invest 1000u, using ten times leverage to go long and short.
When opening positions, it's easier to take market orders, and the transaction fee adds up to 20000×0.0005=10u.
When closing positions, it's for take profit or stop loss, and the transaction fee is 20000×0.0002=4u.

Total wear and tear is 14u, gaining an account with a 250u vault limit.
At an annualized rate of 150, this account earns 1.027u per day, and after two weeks, it will be pure profit.
In fact, if the operation is a bit more meticulous and limit orders are used when opening positions, total wear and tear can be 8u, and profit can start one week after recovering the wear and tear.

The annualized rate of edgex is quite stable. According to the official roadmap, the permissionless liquidity module is not expected to be online until the fourth quarter. Before that, the official only vault's annualized rate should not have significant changes.
This means there are still 3 months to enjoy this high annualized return.
