Warning: This setting may require some tweaking on your part, so if you do not have time to do this, do not update right now. Setting Use Dynamic Timer to OFF will result in Speeder performing its usual, old operation.
New MARKETBOARD setting:
Use Dynamic Timer — If ON, "Adjust Price Marketboard Listing Wait Time" will be the amount of time to wait between each block of listings. This will ensure all listings are read unless you have the wait time set too low. It will also read the listings as quickly as possible if there is only one "block." If OFF, the wait time becomes static, and Speeder will wait that exact amount of time for every item.
This requires updating Speeder to the newest version.
