I've personally had this happen to me on a couple of very small accounts i was running at very high risk (not
fapturbo).
It shouldn't be a concern if you are using reasonable levels of risk, especially not if you are not holding trades over the weekend (i.e. just using
FAPT scalper). Any LRR of 40 or under shouldn't cause you any problems, even in extreme situations.
Some brokers GUARANTEE that you will not lose more than you deposit- you should check with your broker. The majority you can get into debt with though.
