<x-html><html><head></head><BODY bgcolor="#FFFFFF"><p><font size=3 color="#000080" face="Book Antiqua"><i> Hi Guys,<br>I recently started trading the Currencies. I have found substantial differences between the data reported by CME and my data vendor, Reuters Trend Datalink ( I use the MS 6 Downloader ).<br>I called Reuters ( talked to a guy named Skip ) to let them know about this, they said their data matches the Wall Street Journal data. <br>My question is : which data is the "official" or correct one?.<br>Following is an example of this week's data differences :<br>Future : Sept 97 D Mark.<br><br>Date Source	Open		High		Low		Close<br><br>7-21 CME .5593		.5602		.5581		.5589<br>	Reut.	.5613		.5619		.5581		.5589<br><br>7-22 CME	.5539		.5542		.5500		.5502<br>	Reut.	.5588		.5590		.5502		.5502<br><br>7-23	CME	.5488		.5508		.5481		.5494<br>	Reut.	.5504		.5520		.5476		.5494<br><br>7-24	CME	.5466		.5493		.5493		.5468<br>	Reut.	.5496		.5505		.5493		.5468<br><br>As you know, it's very unlikely to have two data sources to match exactly, tick by tick, buy hey, these are ENORMOUS differences,also, they occurred FOUR DAYS IN A ROW ! ( I haven't checked prices for 7-25 yet) like the Open prices for 7-22, that point difference, 49, ( 5588-5539 = 49 pts. ) is more than $ 600 !! ( $ 612.50, to be exact ).<br>In my personal opinion, CME is the correct source. When I trade, I watch the market from the opening bell and I know where the market opens ( at<br>5539, not 5588 for 7-22 ). However, is it possible that, for some reason, CME<br>screwed up and The Wall Street Journal has the correct info.?, I don't think<br>so, since CME is where the trading is taking place. Where the WSJ gets its data, I don't know, but something's wrong here.<br>I already addressed this matter to the CME, keep you informed on what the deal is.<br>It's not my intention to discredit Reuters, I just want to be using the most reliable data, whether it is from the WSJ or CME or whatever source. IF the outcome is the WSJ is wrong, then Reuters needs to make the adjustments accordingly; IF they don't, then I'll find another RELIABLE data source. <br>Think about it, guys, the numbers you're crunching with whatever indicator you're using are going to give you signals based on the data you have, and if your data is messed up, what are your chances to make the right<br>decision ?? ( let alone how accurate your system / method is ! ).<br>.... Have you checked your data, lately ?<br><br>Efrain R Portales<br>e<font color="#0000FF"><u>frain12@xxxxxxxxxxxx</u><font size=3 color="#000080"></p>

Reuters supplies futures data for about $25 a month. I'm
using it this month and I like the service. I've heard bad
comments about Dial Data. Have had not personal experience
with them though.
With Reuters you pay the $25 fee for the month whether you
start on the 1st or the 25th.
They have Continuation charts for every contract which is
nice.
You can reach them at 800-346-2024. Ask for the Futures
package. For $10 more/month you can add unlimited quotes on
the indices. Be sure to wait for the first of the month to
start. If you sign on now you will get hit for $25 for
July.
