You did not fill the Loompoint cost field. As manual state - it is always necessary.

Just as an example - it is working:

It is, however, incorrectly works with items with names consisting of more than a five words. I will try to fix the problem.

Your manual actually does not state that anywhere.  CTRL+F "cost" no result.  CTRL+F heirloom, one result:

Now if I fill in the cost of heirloom and check the box for "item2item" I hit "start" and the screen just minimizes/disappears. 

Sweet program!

*EDIT* I see you say it doesn't work with items over 5 words long...that's what I'm searching for (Lordly Heraldic Surcoat over Mail and Plate)

Very cool !

When you say you are using Dijkstra's algorithm, does that mean you are giving weights to trades according to their gold and heirloom point balance, then finding the shortest path ?

In that case is it possible to put the program into an infinite loop if there's a profitable cycle on the market ? Also how do you weight heirloom points versus gold ?

Also isn't this making a lot of requests on the cRPG server ?

It actually says that:
1. List of source items separated by commas.
2. List of target items separated by commas.
3. Price of 1 loompoint (no delimiters) (necessary)
Just Ctrl+F is not effective sometimes.

That is strange. Can you run it in console mode  - there should error log in console.

Not to trades, but to thier "connections" (edges in graph termins), but in general you are right. Basically connection weight means how much you have to spend to get from one trade to another.

Not to "infinite" (because for now you have to manually download html file) but very long. In fact, "arguments from file" mode was made specially for this.

Simple - all turned into gold, according to loompoint price - that is why it is necessary.

No, because for now you have to download file manually.

Thanks for the clear answers

No, because for now you have to download file manually.

I feel stupid now.

I didn't mean inputting very long argument lists. I don't think my question was correctly spelled, so here's an example. Imagine you have on the marketplace one trade that says "selling MW longsword for 800k" and another offer that says "buying MW longsword for 850k". If you did not tag visited nodes, you would get infinite cycles this way.

One last thing, the number formatter doesn't like numbers with group separators. So people who can't get this to work at all should check that they have nothing set as group separator in the website's settings.

In before someone uses this and gets a chain of trades 10 items long... then halfway through one of the items gets purchased by someone else.  :mrgreen:

There's almost no trade chains longer than 3-4 (implying you don't add 50k+ gold on each).

Now I understand. Ofcourse I`m tagging visited nodes, as it is a part of Dijkstra algorithm logic. So it was made from the start.

Hotfix 0.31 is out - solving parsing problems (now program can work with items with more than 5 words length).
Also I wanted to demonstrate graph creating feature of this tool. For now it has no real purpose and I made it just for fun. The tool outputs graph of deals into text file, which can be turned into .svg by GraphVis tool to look something like this. Looks really cool to me  :) .

Great now nobody will ever get a chance at a good offer for as long as the marketplace jews have this utility!

Why use the word jews?
