Stop-out levels and the leverage trap in short bursts
A margin call at 100% and stop-out at 50% sounds like plenty of room. It is, on a swing trade. On a scalping account running high leverage it is a different story.
Consider a trader using 500:1 and opening several positions in quick succession. Margin used climbs. A fast adverse candle drops equity, the margin level slides past the stop-out threshold in seconds, and the platform closes the largest losing position first. By the time the next price tick arrives, that closure has happened at the worst price.
What makes this nastier than it sounds is the speed. There is no warning. The margin call notice shows up after the stop-out has already been executed, because the server evaluates continuously and the client updates later.
A habit that helps: watch margin level, not just free margin, and keep it far above where a single bad candle could drag it. Many scalpers run at 2000% or more as a baseline for exactly this reason.
The other habit is knowing the broker's stop-out rule. Some close one position at a time, others close everything, and a few use the largest loser first while others use the most recent.
Which stop-out rule does the current broker use, and was it ever tested or only assumed?
