Start from risk, not leverage
Most blown-up high-leverage accounts began with a leverage choice. Professionals reverse the order:
- Risk amount = account × risk %. On a $1,000 account at 1%, that is $10.
- Stop distance = the distance from entry to where your idea is wrong, as a fraction of price.
- Notional = risk amount ÷ stop distance.
- Margin = notional ÷ leverage, and the leverage only has to be high enough that the margin fits.
notional = risk $ ÷ stop % · margin = notional ÷ leverage
Worked example. Bitcoin long at $60,000, stop 0.5% below at $59,700. Risk $10 gives a notional of $10 ÷ 0.005 = $2,000. At 10x that needs $200 of margin; at 100x it needs $20. Either way, if the stop works the loss is about $10. The 100x trade merely leaves $180 more of your balance free. The position size calculator does this arithmetic with fees included.
The stop must sit inside the liquidation distance
A stop-loss only protects you if it triggers before liquidation. The adverse move to liquidation is about 0.50% at 100x and 0.05% at 1000x on the generic model (see how liquidation price is calculated). If your idea needs a 0.5% stop, 100x already liquidates you at the same level, and anything higher liquidates you first.
The table sizes a trade for a $1,000 account risking 1% ($10) and shows the highest leverage that keeps liquidation at least 1.5× the stop distance away, so ordinary slippage past the stop does not turn into a liquidation. Two liquidation models are shown: the generic maintenance-margin model and the 80%-to-85% margin-loss rule used by LeverUp.
| Stop distance | Notional to risk $10 | Margin at 10x | Margin at 100x | Max leverage (generic) | Max leverage (loss rule) |
|---|---|---|---|---|---|
| 0.1% | $10,000 | $1,000 | $100 | 333x | 533x |
| 0.25% | $4,000 | $400 | $40 | 133x | 213x |
| 0.5% | $2,000 | $200 | $20 | 80x | 106x |
| 1% | $1,000 | $100 | $10 | 50x | 56x |
| 2% | $500 | $50 | $5 | 28x | 28x |
| 5% | $200 | $20 | $2 | 12x | 11x |
The pattern is that a tight stop is what makes high leverage tolerable. A 0.1% stop supports several hundred times leverage, while a 2% stop caps you at about 28x. If your stop has to be wide because the setup needs room, you need low leverage, whatever the exchange allows. 1000x is only coherent for a stop of a few hundredths of a percent, which is smaller than the spread and slippage on many markets.
Include fees in the risk number
Round-trip fees add to the loss when the stop is hit. Using notional = risk ÷ (stop % + 2 × fee rate): with a 0.045% fee per side the 0.5% stop example above becomes $10 ÷ 0.0059 = $1,695. At very tight stops the fee can be the larger part of the denominator, which is why scalping at extreme leverage is dominated by costs. The multiples are in the table on what 1000x leverage means.
Funding at high leverage
Funding is paid on notional between longs and shorts, usually every 8 hours on centralized exchanges and sometimes continuously on-chain. Measured against margin, it grows linearly with leverage. This table assumes you are on the paying side and holding for 24 hours (three 8-hour intervals) at three illustrative rates:
| Leverage | 0.01% per 8h | 0.03% per 8h | 0.10% per 8h |
|---|---|---|---|
| 10x | 0.30% | 0.90% | 3.0% |
| 50x | 1.5% | 4.5% | 15.0% |
| 100x | 3.0% | 9.0% | 30.0% |
| 500x | 15.0% | 45.0% | 150.0% |
| 1000x | 30.0% | 90.0% | 300.0% |
At 10x funding is a background cost. At 500x to 1000x it can consume the margin in under a week even if price never moves, which is another reason these trades are short. Rates swing sign and size with positioning, so look at the current number for your market on fundingrates.app before you hold a position through an interval.
Slippage, oracles and wicks
Slippage works like fees: it is charged against notional and lands on margin multiplied by leverage.
| Leverage | 0.01% slippage | 0.05% slippage | 0.10% slippage |
|---|---|---|---|
| 10x | 0.1% | 0.5% | 1.0% |
| 100x | 1.0% | 5.0% | 10.0% |
| 500x | 5.0% | 25.0% | 50.0% |
| 1000x | 10.0% | 50.0% | 100.0% |
- Stops are not guaranteed. A stop becomes a market order; in a fast move it fills beyond your price. With a 0.50% liquidation cushion the gap between stop and liquidation can vanish in one candle.
- Oracle versus chart. Liquidation uses the venue's mark or oracle price, which may update more slowly than your chart or include prints your exchange does not show. Know which one your venue uses.
- Wicks are normal. Thin books and liquidation cascades produce spikes that retrace within seconds. A wide stop survives them; a high-leverage position often cannot.
- Events. Data releases and exchange outages widen spreads exactly when you need to exit.
A short rulebook
- Use isolated margin so a liquidation cannot take the rest of your balance.
- Risk a fixed small share of the account per trade (0.25% to 1%), and cap daily loss.
- Choose the stop first; compute size and leverage from it; reject the trade if liquidation is not at least about 1.5× the stop away.
- Do not add to a losing position or widen a stop to avoid liquidation.
- Prefer limit entries and exits to reduce slippage; test the venue's fills with a small size.
- For 500x and above, treat the margin as money already spent. Size it to an amount you would be fine losing every time.
- Choose the venue for its liquidation rules and liquidity first; see highest leverage exchanges and, for one venue's rules in detail, the LeverUp 1001x guide.
