Minimum Capital Required is not the initial equity that strategy developers entered.
It is a number, based on software analysis of a developer's trades and trading style, that describes the smallest amount of capital required to follow the system at a low "AutoTrade Scaling Factor."
It's calculated by looking at what margin was required to trade at a minimum autotrade scaling factor (based on past trade history) which does not result in account oscillation (i.e. no rounding, no position truncation). In addition, a buffer is added based on historical drawdown and volatility.
Developers cannot manually set Minimum Capital Required at this time.
