Leverage, for those who choose it - and the call that follows

In futures, leverage is how the instrument works. In commodity CFDs it was the only retail door. In equities, uniquely, there is an unlevered way to hold the exact same asset - so this lesson is about machinery that only runs if you switch it on.

The machinery, imported whole

Choose the CFD and three tracks of margin mechanics arrive unchanged: equity marked continuously, the call when it breaches maintenance, the forced close below stop-out - work the example. What sharpens it here is the underlying: module 1's halving means a single name can cross the entire distance from healthy to stopped-out in one auction print, and module 6's cap logic applies with the leverage multiplying every percentage. A 5:1 position in one name is the concentration lesson and the leverage lesson compounding each other.

The equity-specific reading of the worked numbers

• The 30% cushion sounds generous - and is two bad earnings prints in a volatile name, or one halving's first half.
• The stop-out realises 80% of the account on one name's move: the per-name cap from lesson 6 exists precisely so no single story can do this - leverage does not suspend the cap, it tightens it.
• None of this machinery exists on the cash side: the same shares, owned, cannot be called - the freedom lesson 1 warned about, now visible as the alternative the wrapper trades away.

The honest frame

Leverage is not the villain of this lesson - it is a priced service with real uses, and module 3 costed it honestly. The point is narrower: in equities every margin call was optional twice - once when the wrapper was chosen, once when the size was. A trader who meets one has made two decisions the cash alternative never asked of them, and the plan's job is to make both decisions visible at entry: wrapper chosen for the holding period, size inside all three caps, and the leverage line of the risk plan filled in before the position exists, not after the call arrives.
