Hi guys,

i was not sure about where to post this, but probably market forum is a best fit.

I have a tool that works this way: i have a list of items, virtually all the market items of eve, and a list of systems of interest.

The app is able, for each item, to spot in which system the item has the more convenient price, and compares such details with the ones for the item in all the remaining systems.
At the end of the process, for each item i have a list of couples :

(buy place, sell place, buy price, sell price, perc, volume)

Imagine something like:

1, jita, hek, 10, 11.1, 1.1%, 232
...

All this is calculated by fetching the CREST api

When this list is created buy and sell prices are verified using eve marketdata api: if the real price confirms the data, i might in theory buy and resell, after movimg the goods.

Moreover, I have also weekly and montlhy map reduce jobs that crunch me numbers for each item, giving me trends and patterns (over weeks and months timeframe).

To me that is just a techical exercise, i will probably pump 50B into this sooner or later, but my question is: what kind of service would you add to such a tool ?

What kind of feature would you add or,maybe, have never been able to find around ?

Thanks in advance,
BM

I'm just wondering, where are you getting system specific buy and sell prices from? As far as I understand, the CREST API doesn't report today's prices and it also only reports the maximum and minimum prices from each day, meaning a single outlier will completely skew the price ranges? Or is that not correct at all?

What I think he's doing is using Crest to find the "interesting" trades that deserve further investigation. The specific items are then queried in EVE_Central to verify the prices and confirm the opportunity.

I'd be interested to see it, somehow, tied to Dev Blogs and patch releases. The rest of functionality is just presenting trends and prices in different ways.

Hi guys,

thanks for the responses, i was almost sure that this post was perceived as a way to "steal" ideas, while i am absolutely just asking for curiosity (I am not sure i am going to implement complex ideas, they take time).

First of all most items present a fluctuation pattern on an also weekly basis, and that might be interesting in order to understand in which days of the week is good to restock (yes we know all that in the weekends there is way more pressure on the markets, but looking at numbers might be more interesting).

Second, i use eve-marketdata in order to have a precise verifying of the so called "interesting" trends.

And recursively, paterns might be recognized on a monthly basis (if not big hit from the outside occurs, of course).

These have been the ideas that inspired the work, now i am evaluating js data visualization library and integrating it in angular in order to have a nice user experience.
