Who StaxInvesting Is Not For

Most companies write pages explaining who should buy. This one explains who should not, with arithmetic rather than adjectives. If your account is too small, the software cost alone is a hurdle most strategies cannot clear.

A trading bot is a tool. A strong strategy is an edge. But neither one saves you from bad sizing, bad habits, or unrealistic expectations. The traders who get the most out of automation are not the ones looking for a shortcut.
