Item trends

[Kaptard]

The frontpage, as well as search results and similar pages would heavily benefit from the display of item trends. Use this thread to post any useful ideas for trends.

Starting off:

• Highest demand increase relative to supply change (e.g. +120% demand with supply only at +10%, indicating a good niche to trade in)
• Highest price increase in last day (minimum of ~100 priced orders for accuracy)
• Most popular (highest demand + supply + page views)
• Highest price with highest demand (super useful for sellers)

• Median prices over a week
• Median price changes since vaulting (if vaulted)

Maybe a future price prediction (be sure to include a HUGE disclaimer that it is just an estimate tho lol). I am currently working on some techniques based off the data from warframe.market that I might put up (sadly in Python but I guess the process is what's important).

So far I have set up a Monte-Carlo simulation and was considering implementing a recurring neural net but the data available on WM alone might not be enough. However the data that you have (like supply-demant ratios, in-game availability such as un/vaultings, trade-chat population, active users, prices, etc) and other data that can be calculated from this could be enough to deploy a RNN that's remotely useful (provided the computing power is adequate)

@DelSquared Experimental price predictions will be part of the core price graphs sometime in the future, although applying that data to trends is also an interesting idea. 👍

Coincidentally Google just launched Tensorflow.js
