Use this operation after importing an account or correcting its cash balance. It moves today’s daily-loss anchor to the account’s current cash balance while preserving the existing dollar loss allowance.
operationId: reanchorDailyLoss A firm API key can call this route for an account in its firm. The operation:
  1. Calculates the existing allowance as previous start_of_day_balance - previous daily_loss_limit_trigger.
  2. Sets start_of_day_balance to current balance.
  3. Sets realized_day_pnl to 0.
  4. Sets daily_loss_limit_trigger to the new anchor minus the preserved allowance.
  5. Publishes balance.updated so live risk enforcement uses the new trigger.

Migration example

An imported account was created at $50,000, with a $1,250 DLL:
After a migration withdrawal, current cash is $47,685.28. Re-anchoring produces:

​
Response — 200 OK

This operation anchors to cash, while the firm daily-loss breach compares live equity with the resulting trigger. Flatten positions before re-anchoring if you need exactly the full DLL allowance from the account’s current state.
Re-anchoring starts a new daily measurement window and clears realized_day_pnl. Use it for migration or an explicit administrative correction before trading, not as a routine way to restore intraday loss room.
Re-anchoring updates the DLL anchor and trigger, but it does not unlock an account that already has a hard daily-loss breach. Correct the account before it breaches, or use the applicable breach-review workflow separately.
