Scaling percentage

Can the scaling percentage be less than 1? When trying to change to 0.5% I encountered the message to please only enter integers 0-9 in the quantity field.

Anything lower than 1% will cause oscillation in the brokerage account. Precaution should also be used when selecting too low of a percentage that will cause AutoSync to try to trade anything smaller than a full mini lot. This scenario will also cause oscillation.
