Before increasing size, preview required margin under your current leverage and symbol contract. This reduces surprises when multiple positions consume the same equity pool.
Stacking matters
Margin requirements add across uncorrelated positions in many models. A “small” add can be the straw that shrinks free margin.
Policy changes
Leverage caps can change with jurisdiction or account type. Re-run assumptions after any account update.

Stacking orders without stacking surprises
Before you add a fourth correlated position, sum required margin across them at the worst plausible drawdown equity, not only at entry equity. Stress cases reveal whether your cushion is real.
Leverage tier changes
When leverage drops—common around major news weeks or jurisdiction rules—recalculate everything. The same lot size can flip from “easy” to “impossible” overnight.
