This is an estimate of what you feel is the required capital to trade the system(s). The estimate given is used principally to cover the high end of the range of capital necessary to reach an achieved probability of .999.
This estimate and the actual degraded P&L string profit (after parameter and sampling size correction) will combine to prepare the range of capital values shown on the charts. If care is taken to choose a capital stake that will likely produce a successful result, the capital stakes used to prepare the probability charts should be appropriately spaced.
