I now run an ethereum node to catch the txpool statistics. This resembles what ZenGo provided for a while.
My script properly manages deals that are postponed, since they are waiting on a low cost deal to verify initially. So if you send out a deal with a low cost followed by numerous deals by a high cost, the high cost deals are put in the very same color stripe as the low cost deal. This is the primary distinction in between my chart and ZenGo's chart.
