Forwards track the number of sales for a collection.
You have to take shots to make goals. That’s where your forward comes in to play.
The number of sales for a collection changes from week to week. If the sales are higher it may mean that the project is active and more people are eager to be part of the community. There tend to be more sales immediately after mint and soon after an airdrop. Sales can also rise when things aren’t going well. High sales may mean that holders are dumping their assets and exiting the project. In either case, the number of sales in a week is an important statistic to track. Often the number of sales outpaces the amount of ethereum moved because many less-expensive sales occur at the floor.
To convert the change in sales to points we want to calculate the difference between the number of sales this week and the number of sales last week and determine the rate of movement from the previous week (growth or contraction).
(Number of sales current week - Number of sales previous week) / Number of sales previous week
Looking at the World of Women through the month of May we see:
May 1-8: 104 sales
May 8-15: 186 sales
May 15-22: 71 sales
The number of sales per week changes pretty drastically. We see a large bump early in May followed by a precipitous drop (this is also reflected in the ethereum moved for World of Women). In the above example for the week ending on the 22nd we would see:
(71 - 186) / 186 = -0.61827956989
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: -61
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 - 61 = 39
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.
