Midfielders track the amount of ethereum moved for a collection.
Ethereum moved is also known as the project volume. Increased volume generally means increased energy, which is often good. Like the total number of sales statistic (midfielders) increased volume can also indicate negative energy. This makes it important to predict whether or not a collection will be active in either direction. In either case increased volume is good for the project (which takes a percentage of sales).
The amount of ethereum moved per week specifically refers to the amount of ethereum moved as part of sales.
Looking at the World of Women through the month of May we see:
May 1-8: 697123060426.3544
May 8-15: 1016482118431.7881
May 15-22: 403368300113.5134
Here the amount of ethereum moved per week changes pretty drastically. We see a large bump early in May followed by a precipitous drop.
To convert the change in ethereum moved to points we calculate the difference between ethereum moved this week and the ethereum moved last week and determine the rate of movement from the previous week (increasing or decreasing).
(Eth moved current week - Eth moved previous week) / Eth moved previous week
In the above example for the week ending on the 22nd we would see:
(403368300113.5134 - 1016482118431.7881) / 1016482118431.7881 = -0.60317226166
It is unsurprising that most projects have a negative rate of change during the month of May, given the bear market. Again we can think about the points here as resistance to the bear market.
To convert the percentage change to points we can simply take the percentage and round the result. This would mean that in the above example, the points would be (before any multipliers):
May 22: -60
This is great when the project is healthy, but it is very likely that some projects will run negative. Every critter starts at 100 points so the final value would be:
May 22: 100 + -60 = 40
We don't let the total points go below 0.
Sales are any transaction that occurs which transfers ownership of an asset from one account to another and has a value greater than zero. There is one exception currently: if the value is 0.005E it is ignored. This is commonly added as a (non-sale) transfer fee (for example, on NFTTrader.io). We do not count bundles or sweeps when calculating the median sale price, though the total volume is counted in those cases. We also do not currently track WETH sales (the ethereum value is technically 0), though we hope to incorporate this soon.
