There are several reasons that could trigger this:
- Stop-loss price has been reached and your position has been liquidated automatically.
- There has been not enough funds on your account to pay rollover fee.
- Market conditions have triggered our safety mechanism, and we have closed your position to prevent loss to you. In case the price is approaching towards the stop-loss price, regardless of the fact how much near it is to the stop loss threshold, the number of orders in the queue in the order book are considered. For example, if your stop loss is $250 and the current market price is $280 but there is only one order left at the price $280 with small amount and the next order is $249.99 the safety mechanism will close the position considering that keeping the position may cross your stop loss and this would be a breach.
