What does Repay/Recall in SLB mean, or how to foreclose the SLB position?

Repay:

Repay in SLB (Stock Lending and Borrowing) refers to the process where a borrower returns shares to the exchange. Unlike waiting for the settlement period to end, borrowers can promptly return shares, and the exchange reverses the margin amount on the same day the shares are returned.

Recall:

In SLB, Recall occurs when the lender wants their shares back before the contract’s expiry. To initiate a recall, the lender can place a recall order in the same series in which the shares were lent. It’s important to note that the success of the recall isn’t guaranteed, as it depends on factors such as price and open orders. Alternatively, if the lender urgently needs the shares back, they have the option to recall the shares at the prevailing market rate.
