I noticed in another thread here that if you are a satellite feed subscriber you can purchase the net based feeds at 1/2 price (correct?) for historical data fills.
My question is if you are logging all trades for all US equities via the satellite feed, how do you know if you miss some trades? Are there sequential id numbers for the trades per stock?
How do you know what to fill?
Thanks

The backfill option is meant for long term or known outages. For example, a large storm comes through and knocks out the satellite signal. You could then fill in data for the day. It isn't meant to fill in data for people who are in need of the full market. It is for people feeding a client application for technical analysis with a limited number of symbols.
If you are in need of something that can truly fill in lost data at the tick level for the entire market, our NxCore is the best Option. The entire feed is Internet based, and if you ever loose connection or have trouble, you can quicky and easily have the system fill in the missing data (automatically).
