How would the algorithm be impacted by this? For reference, see to following link sent to me by IB: https://www.clientam.com/en/index.php?f=14527#sf_stockYield

According to above, a "cash collerateral" would be deposited on my account. Also, I don't know how the shares I own would but potentially lent would be represented. It sounds as if it could mess around with the algorithm potentially. Has anyone tried this?
