How High Is Too High

A ladder doesn't warn you which rung is unsafe. It just holds — right up until the one that doesn't.

Leverage is the same. 2x doesn't feel different from 10x while the trade is working. The difference only announces itself on the day the trade isn't, and by then you're already standing on the rung you chose.

This chapter is the ladder, rung by rung, with what actually breaks at each one.

1x — no leverage, the baseline everyone should measure against

Buying shares outright, fully paid, no MTF, no borrowed size. Nothing to force you out early except your own decision. This is the only leverage level at which a stock can go to zero and you still have zero debt — you simply lose what you put in, and nothing more.

2x-3x — the range where most disciplined MTF and conservative futures use sits

At this level, a stock would need to move roughly 33-50% against you before your capital is fully wiped out, assuming no maintenance margin top-ups along the way — a large move, but not an impossible one in a bad month for a volatile stock. This is a leverage range where a stop-loss discipline and reasonable position sizing can realistically keep a single bad trade from being account-ending, provided you're actually using them.

4x-5x — where the math starts working against forgiveness

A 20-25% adverse move now wipes your capital in the position. That's a move plenty of individual stocks make in weeks, not months, especially around results or sector news. At this level, the gap between 'a bad trade' and 'an account-threatening trade' has narrowed enough that position sizing has to actively compensate — a full-size position at 5x leverage is a very different risk than a half-size position at 5x leverage, even though the leverage ratio quoted is identical.

10x — the range where a single ordinary bad day can be terminal

A 10% adverse move erases your capital. Individual stocks, and certainly crypto and forex pairs, routinely move 10% intraday on ordinary news, let alone extraordinary news. At 10x, you are no longer protected by 'the stock would have to do something unusual' — ordinary volatility is sufficient.

20x-100x — the range this school considers structurally incompatible with a plan-first approach

Available on some crypto perpetuals and offshore CFD/forex platforms. At these levels, a 1-5% adverse move — well within a single hour's typical noise on a volatile instrument — is liquidating. This isn't a leverage level where risk management adjusts to compensate; it's a level where risk management has effectively been made irrelevant by the math, because the margin of error is smaller than the market's own normal breathing room.

The honest way to pick your rung

Don't start from 'what leverage does the platform allow.' Start from 'what percentage move against me can this position survive before I'm forced out, and is that percentage bigger than the moves this instrument makes on an ordinary bad day?' If the answer is no — if your liquidation distance is smaller than the instrument's normal noise — you haven't taken a leveraged position. You've set a timer.
