Market Discussions

Looks very interesting, the investor report is quite nice! Additional information which could be of interest:
-total volume
-sell/buy volume
-returns on total volume/NAV
-returns/volume for each of the 10 items with highest volume+returns and of the 10 items with lowest volume+returns

A few issues I noticed:
-Log-in form says Email/Username, however only logging in using Email works
-I get an annoying browser security warning because of url mismatch of the certificate used I think

Ideas:
I understand that while this started with open source eve-profit and has evolved into your own project, there are still some features of eve-profit that could not only be useful but also be expanded upon, for example:
-filter by item/items
-viewing of different timeframes
-table of items and possibility to sort in various ways (profit %/ISK, volume ISK/units, etc.)
-stats on taxes and fees
-more filtering/sorting in general, for example by region/system/station, price/volume/profit of items or locations and probably more stuff
-option to add/remove graphs to investor reports
-include assets at some point


All in all your project looks very promising and I hope you keep working on it!

I really LOVE this. The investor report makes it easy to see the traders capabilities. I've been using this since july(?).

I've been thinking of adding a page like that, one that displays your current stock as far as the database sees. With a preference for your desired return percentage would be pretty easy to add, and using that could calculate the RRP/minimum price. I will keep that in mind when I develop that module.

Thank you I Was There, your help the past 3 months has been invaluable.

I currently do not have any way of tracking reprocessing items and getting that profit. I may take a look at it down the line, but it's not currently a priority.

From what I understand, is that the old program wouldn't differentiate between the 1mn and 100mn items? Not sure how that happened.

My script works on item ids, not names. Even if the names are similar, to the programs eyes, they would be very different. I don't see any scenario where that would happen in my program from what you're explaining.

Whenever I develop the stock module, showing your current stock/value/etc, I will have a way to remove stock without "selling" it. For example you purchase a hurricane for personal use, but you're also trading hurricanes, you can remove one hurricane from your stock. This is what I think you meant to mean, am I correct?

In that case, expect to see that function in the coming week, the stock module is high up on my priority list to complete.

You are correct. It would actually be 55k, minus the transaction tax.

The one thing the program does not track, is the broker fee when setting up the order. I could not find a quick and viable way to apply that tax to every transaction.

I would also like to state that the automatic API pull has been disabled for the past few hours. I have to optimize some database queries to reduce the strain on the hardware. I expect it to be finished in 6 hours at the latest.

EDIT: Was done quicker than I expected. It'll run for now but I will be having a close eye on the usage. You may be missing a few transactions/journal entries due to downtime and possible corrupted api pulls. From now on it should be pretty accurate.

It is calculated using FiFo logic.

If you want more indepth, here is my logic.

1. Transactions and journal entries are pulled and stored into the database.
2. For every transaction, I figure out if its buy or sell, if its a buy I go into the "stock" function. It then looks up journal entries and calculates the total price you paid (transaction tax + unit price * quantity not the exact formula, close enough though). It stores that new unit price, and quantity for work later.
3. For every sale, I pull up the oldest "stock", figure out how much I need to use of the row of stock (if I need another row, depletes it completely, or uses partial). I then calculate profit with the (sell price - buy price) * quantity, and I store that as profit. Then it removes the amount of stock I used from the database.
4. The profit percentages on screen are all calculated and rendered from that information.

If one of you signs up for this and doesn't get a confirmation email, check your spam folder.

edit: I get an HTTP 500 error when I click the wallet refresh button on the character page. My buyer character is listed as having 0 isk but he has billions.

One thing that would be a great help would be the ability to ignore a buy. For example, I recently bought about 2 Billion in items to resell, which were then blown up when getting hauled by a hauling company. I got the collateral back, so I did not lose anything in the deal, but now my profits are going to be all off, becasue when I re buy the modules it will be at different prices. So it might show a loss on the items when I sell them if they sell for less then what I paid for the modules that were destroyed. This would also help with items that are for personal use. That way they just would not be in the stacks that you pull inventory out of.
