LU/LD Options Trading Rules

The following LU/LD rules apply to options trades:
•When the underlying security goes into a limit or straddle state any market order entered at that time will not interact within the market until the limit/straddle state is resolved.
•Stop orders with an exchange will not be allowed to trigger (or become an executable market order) during a limit or straddle state.
•Limit and stop limit orders with an exchange will continue to be executed in the limit and straddle state.
•No trading will occur when the underlying stock is halted.

How You'll Know When an LU/LD Trading Halt Occurs

From any of Scottrade's platforms, you'll be able to see when a Limit Up/Limit Down trading halt is applied to a security in three places:
1.Your Watch Lists
2.From a Detailed Quote
3.At Order Entry

If a security is currently halted because it's trading outside its price bands, you'll see a small yellow box next to that security. The letters inside the yellow box indicate why the security is halted:
•a ‘B' indicates that a security is non-executable because the BID is outside the price band
•an ‘A' indicates that a security is non-executable because the ASK is outside the price band
•A ‘B/A' indicates that the BID and ASK are non-executable

To see more information on LU/LD trading halts, you configure your watch lists to show the upper and lower price bands for a security using the configure settings on Scottrader® Streaming Quotes and ScottradeELITE® or the Edit Watch List feature in the Scottrade® client website.

The images below show how LU/LD trading halts are communicated across our different platforms.
====================================

Got this from Scottrade's knowledge center.

I was trying to see if some of the trades were reversed. The delayed level 2 I was watching showed some of the trades with a letter I and some with a letter F. I'm not familiar with seeing those.
