essentially, before TF2WH had a to-scale pricing system relative to the normal exchange rate, they had a goofy "about this price" and "maybe about there" system. Essentially, I drew up a giant spreadsheet based off of scrap/sold/bought prices and comparative credit/scrap ratios.

Essentially, I found which items I could sell for a net gain of credits, and what items to cash out on to get a net scrap profit in terms of points spent. I ended up engaging TF2WH in entirely toxic and negative trades.

This could have gone on for months, but the issue there was that I needed to get a trading partner whom could procure these absurd amounts of specific items, in arbitrary bulk. Being a peppy pre-teen I ended up spilling this secret to a bunch of people, and every high efficency trade ended up getting swamped. It was a cluster fuck for TF2WH, I'm pretty sure their stock was so stagnant that they had to liquidate some of their negative investment items.

>get bored and stop trading for a week
>see that TF2WH made a grand announcement that they're changing their pricing systems.

Turns out I showed a large enough portion of the economy how to fucking engage automated trading services entirely in toxic trading.
