simulateBS(param = NULL, seed = NULL, ndays = 60)'alpha', 'delta', 'epsilon_b', 'epsilon_s', 'mu'),
length must equal 5NULL; for more detail see
set.seedndays rows and two columns which are named 'Buys' and 'Sells'.
param or one or more of the vector names do not match the valid choices, they are internally set to
'alpha', 'delta', 'epsilon_b', 'epsilon_s', 'mu' (in this order).
