"I was with ******* for 4 years at $230 a month, this is a huge savings for me, GOD BLESS YOU PEOPLE," - Comment from T.S. via Email
"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

Hello!

We have relative frequent problems with LSE data. (Once per week at least.)

Here is the latest example. Symbol: L.BATS

Here are a tick data downloaded by your Time & Sales application. (Sorted desc.)

We usually receive 100x less price tick than it should be.
I looked to it deeper today and I see that historical data are even in the wrong order.

Thanks.
