Market Discussions

API pulls are working pretty well now, all ready for more users to test!
We've also finished migrating to our new server, and

Some cool facts:
So far we've calculated 120 bil worth of profit for our members.
Give us a try, we're constantly improving and always listening to feedback.
There are almost 200 thousand transactions tracked.
Users currently have 338 bil across all characters

So far I like the tool and the features that are being added.

Yeah, I've been stuck on this for a while. There are three sources of income that I can figure out:

1. Buy item from market, sell for higher price (trade)
2. Buy minerals from market, manufacture item and sell (manufacture)
3. Receive gift of either materials to manufacture or sell directly (gift)

It's impossible to tell at the moment where you received an item (because they could've trashed some items and then you have orphan stock records). The cases where 'gift' comes into play is when a character gets minerals from mining or moon mining (or PI).

You can then cost the transaction at opportunity cost, so you calculate profit with each buy order and each industry job. Since we can't do 'proper' accounting, we have to frig the profit and calculate it at each step. For instance, I mine 20 trit, I build a Raven (let's say that is how much trit it takes to build it). The profit I make is the Raven minus 20 trit at Jita sell price.

If I buy 20 trit, then the profit is the above calculation plus the profit I made on buying that 20 trit (so we buy 20 trit @ 6 ISK when Jita is selling for 7 ISK - that makes 20 ISK profit from buying that trit at the lower price). We can always sell that trit at sell price now, but we decided to make a Raven and sell it, hoping that we could get more than 7 ISK per trit for our time and skill.

By calculating the profit at each step, that makes it easier for us to track - as we don't have to keep track of items we've bought and then check them off, instead we compare everything to market prices and assume all our assets are that price. If we buy something, we profit; if we sell something, we profit, and so forth. This method makes it easier for us and we don't have to do FIFO or whatever. In a perfect world, I guess FIFO would be unnecessary as there would be a global market index of every item in the world, and our accounting systems would use that to calculate profits instead.

The above is my thoughts on getting profit on a per item basis. Global profit day per day is easy in comparison since we only have to compare our assets to the last API call, and the difference in the account balance. I'd be interested if anyone else had some thoughts on how to get a true profit figure for a char/corp?

Nope, the item ID changes, plus the IDs themselves are not unique as CCP cycle through them when they're no longer in existance.

The site doesnt touch the actual inventory of everyone exactly. It works off buy transactions, if you buy 10 units of hurricanes, you have 10 units in stock. Sell it, and those 10 units of stock gets "consumed", and then profit is calculated via sell-price * quantity, then subtract any relevant taxes the script can locate. I see where you're going with your idea, but there are limitations and variables to it. There is no way the script can know exactly what you do with every unit of trit for example, and even if there was an API output, the hardware would not be able to handle the current number of users with that much to calculate.

At that point, it would be more efficient and easier for all users to either a) add/remove stock manually or b) report prices you bought/manufacture an item for.

Down the road, I can see a way to use bought minerals, which now are stock in the site's database, and consume them with a manufacture order that you enter in the mineral usage manually (too many skills, researching variables). Even then, that's not going to be accurate enough unless the end user is 100% on their game with adjusting their stock.

There are a few solutions I have been looking over in regards to non-transaction inlets of stock (contracts, direct trade, manufacture), but I don't currently have a solution I am 100% happy with currently. For the time being, the site only tracks profit for items you sell, that you have purchased and have been tracked before.

@SlayerOfArgus
I will increase the session time, I notice I get logged out as well every few days, but I have autologin set up so I don't really notice it.

I apologize for my absenteeism the past 2 weeks, Thanksgiving was a big event, and I have finals all next week so I have been devoting the majority of my time to studying and classes.
I am hoping to get some code in Saturday evening, when I'll finally have a free few hours.
Once again, thanks everyone for your support!

Does this just track market related income or for example bounty prizes aswell?

If not, could this be a future feature?

Is this still occuring? I hotfixed the file to remove that error.

Your api hadn't been pulled when you checked. Your api gets added to the que and should be retrieved on the next api pull. (every 10minutes, unless there's one going already).

Just checked, and your api was pulled and has been pulling since.

I only pull the last 100 transactions in the transactions page. I am going to move away from that way of displaying info, and migrate to an order view with more info.

I'm also recoding the orders module, it's being inconsistant and I've seen a few bugs.
As for the no profits displaying, I see it is starting to calculate profit just needed some more data to generate graphs and profit.

OK, thx and i'll just wait and see.
