Isn't this just an OUT AND OUT cheat. How can this person get away with this, let alone posting it on this forum. He is taking files form the game reading them and giving people an out of game advantage, using methods not part of the game mechanic and using facilities not available to normal players with out buying a licence from microsoft, and reading game files with a third party device.
THIS IS CHEATING PLAIN AND SIMPLE
This person should be banned.
A few small points for consideration:
Its not really any different to writing things down, I can only see my data which I obtained myself, replacing my paper pad and screenshots full of the same.
Its not live data, If the markets change, I will only find out by visiting the station.
Its not crowdsourced, unlike some other tools I am not downloading market information from every tom, and harry.
FD have a thread on the forums here:

Listing all the tools available. Trading tools, route planners, OCR stuff... etc. Have a read.
Now, why should Eventure be banned again?
I agree, but this is by definition cheating, full respect to the person who created this, it goes to show you the lengths people will go to improve a cruddy game. But a cheat is a cheat, you have to pay for it out of game in real money (excel licence) it is not available to everyone and gives an advantage to those who use it... ipso facto A CHEAT
The advantage being that I save paper, ink and eye strain trying to read my scribbles

As mentioned above, there are many free alternatives, here is IMO a decent and comparible (functionality wise) one which can be used in 'offline' mode for your data only:

But since I have Excel, I'll go for the eye candy this one offers.
