I looked into last night’s liquidation despite the low drawdown today. It does not copy trades based on a multiple of the lead trader’s asset ratio; the small text below says that the copy multiple is based on the lead trader’s value and quantity per trade. For example, if you use 1,000U to copy a lead trader with 10,000U in copy-trading funds, and they open a small position worth 1% of their funds, or 100U, this is an ETH long position worth 10,000U at 100x leverage. Copying it at 10x means a total position value of 100,000U. This can lead to liquidation within minutes, because the corresponding long position for the copying user already uses their entire balance at maximum leverage; even a 1% fluctuation would wipe it out.

I have already reported this to customer service and requested that it be optimized to use an asset-ratio multiplier model. We’ll wait for the optimization update.
