When using Olive's Auto-close, an outcome can be closed 1-day prior to expiry to avoid adverse assignment. This setting allows up to $5 to remove assignment risk which for most is not used in full or noticeable, however, low-cost outcomes can notice a percentage impact on realized value.
For example, an outcome with an Amount Invested of $300 stating a 3% yield could result in a yield of 1.3% if $5 is required to removed assignment risk. As $5 is 1.7% of the amount invested.
