No jokes today: $ETH saw a $3.89 million long position liquidated in perpetual futures trading.
The rule this jokester lives by: keep leverage low enough to sleep soundly, and make stop-losses more reliable than a morning alarm.
A quick serious explainer: when a long position is liquidated, the system sells at market to close it; when a short position is liquidated, the system buys back to close it.
Sizing your position based on your stop-loss distance is much steadier than picking a size by gut feel.
