Hey - quick note on the math in the video to calculate the max buy:

btc = quantity * bid * 1.0025

to solve for quantity, divide both sides by bid*1.0025:

quantity = btc/(bid * 1.0025)

This works out with the numbers in the video around 7:00:

quantity = .00590745 / (.000732 * 1.0025) = 8.050161481542047
