Do the Day-Ahead and Real-Time market clearing algorithms clear Ancillary Services (ASM) products differently based on a unit's ramp rate curve, if enabled?
The Ramp Rate for Day-Ahead is RR*60 minutes. For Real-Time, the Ramp Rate is RR*5 minutes.

Company X is only submitting Day-Ahead and Real-Time offers for 2 days in advance (OD+2 and OD+3) but there are offers in the MISO portal that go all the way out to OD+6. Where are these offers coming from and is MISO able to use them to commit our units? An example would be we only submitted offers for 4/27-4/29, but I see offers all the way out to 5/4 in the portal. 
There are a couple different solutions for this question.

A. Company X submits real-time offers for 5/4, 5/5-5/6.MISO can then copy forward the offer from 5/6 for 5/7-5/9. MISO can then commit our unit for 5/9 on 5/4 for reliability using the copied forward offer from 5/.6 (Yes, MISO would only commit a unit this far ahead if it has a long lead, for example its startup time + notification time is 90 hours. In this scenario, if MISO needs this unit on 5/9 00:00 AM EST because of its economic offers, MISO would send out a notification call on 5/4 or 5/5.
B. Company X is financially bound to that offer (It depends. Take the same example, if it turns out this unit cannot participate on 5/9 00:00 AM and Company X comes because more than 90 hours ahead to turn it off, it is not financially binding. If Company X comes back 85 hours ahead saying this unit cannot be on for 5/9 00:00, there would be charges). MISO would only commit a unit this far ahead if it is a long lead, for example its startup time + notification time is 90 hours.

On the Day-Ahead Product Binding Constraints report, how are the shadow prices (if they are) are reflected in the Locational Marginal Pricing (LMPs). If a constraint is reported as binding in this file, is that price spread reflected in the Marginal Congestion Component of the LMPs? 
A binging constraint will impact the Marginal Clearing Price (MCP). So Regional Dispatch Transfer (RDT) shadow prices would be reflected in LMPs

How do I submit virtual bids and offers through an API? 
The MUI API will provide guidance on that. https://cdn.misoenergy.org/MUI%202.0%20API%20User%20Guide629008.pdf
