Thanks. I think that's a lot less confusing:



Although I think it would be better to explicitly state how things work. A smart investor will want to risk something between 0.5 and 1 times the Kelly amount. First off, they are going to need to know what "bankroll: 621.7470" means. Is that the actual number of Bitcoins you have invested? Or is that the sum of each invested amount times the risk factor? I'm guessing its the latter, but am not sure. That should be cleared up somewhere.

Assuming that is the case, and that I want to risk a full Kelly, I need to set my risk to bank/maxprofit/100 = 621.747/20/100 = 0.31x - which isn't an option. The smallest you allow is 0.5x, which is almost twice a fully Kelly, which is too much.
