This is a simple plugin for EDMarketConnector, based on and adapted from the EDMCJumpSpeed plugin, so credit for most of the work done should be directed to their makers!
As with other EDMC plugins, simply unzip the git directory into your plugins folder (or just place load.py inside a directory within the plugins directory) yielding something like
EDMarketConnector\plugins\EDMC-HourlyIncome-master\load.py
and restart EDMC afterwards.
