floripaolo, you shorted into the following.
GBP strength (please see Dennis's thread)
A weekly, now understand, weeeeeeeeeekly ascending triangle/pennant. This pattern is very strong, in the 15min fractal, I cannot emphasize how strong it is in the weekly.
Breakout above the 151 resistance level.
So you are shorting into strength, if and that is a big IF you had the experience to be counter trend, you would still be to early, but I don't think you were looking for a counter trend.
You need to figure out an exit, and you need to do it quickly.
Also, unrelated to your current predicament, I would humbly suggest that you get a real trading platform, with no accounting glitches. And don't forget in forex trading "a trending market makes everyone look like a genius", I make my bones in a rangy schizoid market, so be careful following too closely behind trend followers, "the trend is your friend, until it bends, and then it ends".
