"I ran your IQFeed DDE vs. my broker vs. a level II window for some slow-moving options. I would see the level II quote change, then your feed update instantaneously. My broker's DDE, however, would take as much as 30 seconds to update. I am not chasing milliseconds, but half a minute is unacceptable." - Comment from Rob

I have seen other data providers send out "ticks" that give the settlement price for the future contract each day at closing; these ticks have a volume of 0. I do not want these ticks.

I only want to follow ticks that represent actual trades taking place on the exchange. What's the best way to achieve this? Would it be the Extended Trade field?

On this same topic, in dealing with @ES# can you tell me the difference between the Extended Trade fields and Last fields? I understand their difference in terms of stocks, but not futures.

In the streaming Level1 feed, the "Message Contents" field will contain an 's' when settlements are sent. For all trades, this field will contain a 'C', 'E', or 'O'.

The same logic is true for Trades in historical data retrieval but the name of the field is "Basis for Last" in tick data requests (and settlements are marked with an 'S' instead of 's'.

The difference between the series of trade identification fields for "Last" and "Extended Trade" is that extended trades also include some FormT trades. As a result, you are correct that for Futures, those fields will contain the same values.

Thanks, Steve.

Consider the following situation:
15:14:59 @ES# trades for 2500.00
15:15:02 @ES# settles for 2500.25
15:15:05 I start a trades-only watch on @ES# with command "t[@ES#]"

I will then immediately receive Summary Message at 15:15:05. In that Summary Message, what will the values of the following fields be:

Extended Trade
Last
Most Recent Trade
Message Contents

In your example, All three sets of fields (Last, Extended Trade, and Most Recent Trade) will reflect the last trade price of 2500.00.

We have separate fields (Settle and Settlement Date) to display the settle information in streaming data. The settlement price is copied to the Close field but never the trade fields.

Message Contents on a summary message isn't very useful since summary messages populate all fields and the purpose of Message Contents is to tell you what was populated in the message.
