You can do this by creating two datetime parameters. The first will use the values from Order Start Date and the second will use the values from Order End Date. Then, create a calculated field similar to the following:
[Order Start Date]>=[Order Start Date Parameter] and [Order End Date]<=[Order End Date Parameter]
Show both parameter controls. Then, place the above calculation on the filter shelf and select True.
Hope this helps!
