Liquidation

Liquidation is the venue force-closing a leveraged position because your collateral can no longer cover the potential loss. It is not a penalty or an edge case. It is the standard mechanism that ends over-leveraged positions, and it executes at the worst moment by construction: while the market is moving against you.

Only leveraged positions can be liquidated. Spot holdings, including everything Anello’s grid and DCA bots trade, have no liquidation mechanics at all.

Why it happens

When you open a perp position you post margin as collateral. As price moves against the position, the unrealized loss eats into that margin. The venue requires a minimum buffer to remain, the maintenance margin. The moment your remaining margin falls to that threshold, the venue closes the position at market to protect itself from your position going negative.

The venue is not making a judgment about your trade. It is solving its own problem: a position whose losses exceed its collateral becomes the venue’s loss, so no venue lets you get there.

The liquidation price

Every leveraged position has a price at which liquidation triggers, computable the moment you open it. The dominant factor is leverage: higher leverage means less collateral per unit of exposure, so a smaller adverse move exhausts it.

For a long opened at $100,000 (simplified, ignoring the maintenance buffer, which moves these slightly closer to entry):

Leverage	Liquidation near	Adverse move that kills you
2x	~$50,000	~50%
5x	~$80,000	~20%
10x	~$90,000	~10%
20x	~$95,000	~5%

Look hard at the last row. BTC moves 5% in an afternoon without making the news. At 20x, ordinary noise, not a crash or a black swan, is enough to end the position. This is the practical meaning of leverage: it pulls the cliff closer to wherever you’re standing.

What you actually lose

When a liquidation executes, the position is closed at market and the margin backing it is consumed by the loss (plus liquidation fees on most venues). For an isolated position, that means the margin you allocated to it; your maximum loss is that allocation. For a cross position, all available account margin backs the position, so the damage can extend much further. The distinction is covered in Margin.

Two things make liquidation worse than a stop-loss at the same price:

1. You don’t choose the price. Liquidations execute at market during adverse movement, often with slippage beyond the trigger.
2. There is no “wait and see.” A spot holder underwater can wait indefinitely. A liquidated position is gone; if price recovers an hour later, you don’t.

Reducing the risk

The levers are unexciting and they work:

• Lower leverage. The single biggest factor; it moves the liquidation price far from entry.
• More margin. Adding collateral to a position pushes the threshold away.
• Stops you choose. A stop-loss above your liquidation price means you exit at a price you picked, with margin left, instead of at the venue’s price with none. On Anello’s terminal you can attach one to the entry itself.
• Isolated margin for experiments, so one bad position can’t reach the rest of the account.

And the structural option: strategies that hold inventory while waiting for recovery, like grid trading, are safer run on spot, where waiting is always allowed. That’s why Anello’s grid bots trade Hyperliquid spot markets. For the full risk picture, see Risks of grid & perp trading.
