When you link accounts for copy trading, Hyperprop coordinates how they close on a shared risk limit, so one account does not end up worse off than the rest of the group.
Closing together on a shared limit
When a shared daily limit (loss or drawdown) is breached, the linked accounts close together at one coordinated price. Without that coordination, one account's risk check might trigger a moment before the others and close at a worse price during a fast move, while the rest closed at a better one. Coordinated closing means the group exits together, at one price.
Followers wait for the lead
On a soft daily-limit breach, a follower defers to the lead's coordinated close while the lead is still holding, so the whole group exits together rather than one follower jumping early.
Each account still protects itself
Coordination never overrides an account's own safety. The hard limits still close each account immediately on a breach, and a follower still closes itself if it crosses its own safety margin. The group coordinates where it safely can, and each account protects itself where it must.
