The micro card shows the same position in micros, ten to each E-mini; when no E-mini fits, it shows the most micros that do. The shaded line in each card shows what the number of contracts you plan to trade would risk. Contracts are rounded down so the total stays within your budget. A stop can fill worse than its price in a fast or thin market, so treat the total as a minimum, not a maximum. This is a sizing aid, not advice on what to trade.
How it works
Every futures stop comes down to one line of arithmetic:
Contracts = risk budget ÷ ((stop in points + entry slippage in points) × dollars per point), rounded down
Your risk budget is your account size times the share you risk per trade. The stop comes from the setup, not from the budget: if a full-size contract doesn’t fit, the micro contract, one-tenth the size, usually does. Margin doesn’t enter into it. The margin your broker asks for says nothing about where your stop is.
