tick data inaccuracies (candlestick probs)

[Mike <pooltreatments@xxxxxxxxxxxx>]

I have tried for a year now to find a reiable data vendor. In aour 
trading group we have
YesterSource
Sad-Signal
Fd-Charts
WrongTick
None of these agree! It is amazing to me that this data could be so far 
out. Using fib retracements and candlestick analysis is more luck than 
anything else. We have had many cases wheer a doji was called on an 
interaday timeframe and half the group dont have it! We have had 
significant lows and highs be out by as much as 1/2 handle on  SP500. 
Its a joke.

I recentlyl learned that CQG might have the best feed available. Can 
anyone confiirm that?

Also can anyone reccomend a book of easy language functiions and some 
more advanced programming techniques for me.

Regards
Mike
