For the upgrade amounts (1,5,25,100,max) could you change “max” to be a configurable percentage of your blocks? For example, if you had e100 blocks you could set it up upgrade up to e98,e97, and so on. You could make it like the slider for autoskip in the settings, where each “tick” of the slider would be one order of magnitude less than your current blocks.
The insider trader perk is very underwhelming for its cost. From what i could tell, a plus hint means the stock is slightly more likely to go up than down, not that the stock is going to go up. A minus hint is slightly more likely to go down than up etc. I would rather the perk just say if the next stock tick is going up or down.
