Been too greedy can actually cause this. Take a scenario where a trader enters every trade with a small position size and he manages to get that trade right and he becomes profitable in them, he continues on this streaks and keeps on winning them all of sudden he decides to go for a big position size because he feels too confident in his set ups and been clouded by greed wanted more profits and all of a sudden this one trade or more ends in lose which could nearly liquidate him probably because he didn’t put out a stop loss. This is how a profitable trader loses and liquidates themselves.

If yuh have good risk management your trades could face even 5 stoop loss and you would still not get liquidated. Also there is a thing in a running trade that causes some traders who might be in profit in that trade end up losing it because they didn’t have break even set on it or even take partials and the trade reverse or change
