The cross-margin mistake that turns one bad long into a wiped account

Thursday's long flush, read through KCEX liquidation rules

By Updated

Key takeaway

Most accounts that got cleaned out on Thursday did not lose because of one wrong call. They lost because one wrong call was allowed to borrow margin from everything else in the account. Beginner tier.

There are no KCEX price figures in this one: the KCEX market feed showed a maintenance page when we checked at 3:55 PM ET on Nov 5, 2026. The numbers below are market-wide CoinGlass totals published Thursday afternoon, and the rules are KCEX's own liquidation rules.

What happened on Thursday?

  • A sell-off in US tech and AI stocks spilled into crypto. BTC fell 6% to 75,700 after an intraday low of 75,568, and ETH dropped more than 7% to 2,247.
  • About 879.92 million USD of positions were liquidated in a four-hour window: 818.90 million USD of longs and 61.02 million USD of shorts. Longs were 93.07% of it.
  • Over 24 hours the total came to nearly 1.1 billion USD, across nearly 211,000 traders.
  • SOL, XRP and HYPE fell 6%-7% on the day alongside ETH. When majors drop together, every long in a cross account loses at the same time.

What triggers liquidation on KCEX?

KCEX watches each position's margin ratio. When the margin ratio reaches or exceeds 100%, the system liquidates. The check runs on the mark price, which blends the index and the market price, not on the last trade. Once triggered, the liquidation engine takes the position over at the bankruptcy price, the price where the position's margin is fully used up.

How does cross margin change the line?

In cross margin, all available margin backs your positions. If one position's unrealized loss grows, every position becomes easier to liquidate. In isolated margin, each position has its own margin, and its liquidation price stays put unless you add margin or change the position.

In formula form:

maintenance_margin = position_value x MMR cross: liquidation when account_equity <= total_maintenance_margin (margin ratio >= 100%) isolated: liquidation when position_margin + unrealized_pnl <= that position's maintenance_margin

How did that play out in a long flush?

  1. Two cross longs, A and B, in two different majors. The sell-off hits both. Their unrealized losses stack, so account equity falls faster than either position alone would drag it.
  2. The same two positions in isolated mode with margins m_A and m_B. A can be closed out while B stays open. The most A can cost you is m_A plus fees.
  3. On a day when 93.07% of liquidations hit longs, correlated longs were the normal case, not the rare one.
  4. Funding also moves the line. In cross, paying or receiving funding changes the margin balance and so the liquidation price. In isolated, receiving funding does not move it, but paying funding with insufficient available margin comes out of the position margin and does.

Why didn't my stop-loss save me?

KCEX lists the usual reasons. A stop set too close to, or worse than, the liquidation price can lose the race. In a fast market, price can move past the stop before it fills. And take-profit and stop-loss orders execute at market, so the fill can differ from the trigger price.

What are the common mistakes?

  • Leaving every position in cross because it is the default you never changed.
  • Opening a second long in a correlated coin to "average" the first one inside the same cross pool.
  • Watching last price while liquidation runs on mark price.
  • Parking the stop right next to the liquidation price.

Quick FAQ

Is cross margin always worse? No. It gives a single position more buffer, because the whole balance backs it. The cost is that the whole balance is on the line.

Where can I see a liquidation after it happens? In Position History, a liquidated position shows the status Liquidated. Order History also has a Liquidation History view.

Does higher leverage change the margin ratio math? It changes how much margin sits behind each position. A smaller margin behind the same position means less room before the margin ratio reaches 100%.

Takeaway: cross margin is a shared fuse, and on a day when 93.07% of liquidations hit longs, a shared fuse burns everything at once.
