So if you mine on middlecoin and like to interpret graphs; take a look at http://middlestats.circlestorm.org/
so from what I understand, the change in wealth graph should track how efficient the trading algorithm is, right?
In a perfect world this would be true yes.
If you stopped mining, the graph would show an even 0 if unexchanged coins were being sold at the expected value.
If the graph were to go positive it would mean the coins have been sold above expected price. The inverse is true for negative values.
I practice it will likely be hard to interpret this graph. But (I hope) it will be much more interesting once the prediction graphing is enabled, since
it will allow you to easily see whether it follow the usual (historical) patterns or suddenly deviates from the norm (a deviation would not necessarily mean something is wrong though).
That is a fantastic statistic.. the fact that it appears to have been positive 90% of the time is a good sign
The only thing I can think would be maybe to have a % value somehow instead of a btc value, as the btc value will depend on the gross value of the pool (sorry if this doesn't make sense, it's before my coffee time)
