feat: improve waiting time for pending market exit orders

The code changes in `Strategy.py` modify the waiting time for pending market exit orders. The previous waiting time was set to 10 seconds, but it has been increased to 12 seconds in order to allow more time for the exchange to respond as expected for order execution. This change aims to improve the reliability of the order execution process.

Note: The recent user commits and repository commits are not relevant for generating the commit message in this case.
