Quote from Leonidas:
See now, I think your execution was fine, but you were effectively wrong on the trade.
What you thought was going to happen didn't happen. You thought you'd have immediate continuation, but price moved into a consolidation pattern instead and stopped you out.
Now, you did have an opportunity to put that trade back on with very little risk to yourself, but the fact remains that you were somewhat right, since price did eventually continue down, but not right enough, since it did so much later than you thought and made you take more heat than you thought you had to take. It's OK, it happens to everyone.
Your execution, on the other hand, was fine from what I can tell. You took a defined signal (trendline break), set a stop, and adhered to it.
Like I said, there some decent reentry points in that pattern, and I marked a chart up for you. Enjoy, and I hope it helps.
