I've experienced a time like this. and of course this makes me worry, when it's available margin in my account so low, plus more to the movement opposed to open market transactions I have done some time ago. and I immediately took action, I opened the transaction inverse / opposite of the previous transaction with a lot less likely to cover the amount of loss, before the market touched the point of support or resistant line. and most traders are wrong and misses the auspicious moment, so the market turned back after reaching the point of support or resistance line. This should be considered by some traders.
however, if this happens you are the availability of sufficient margin to withstand the amount of loss, no need to worry. because the market will turn around again when he touched the point of support or resistant a particular line.
