Sadly, you might be right. Here is a tale of woe to melt even the hardest of hearts...
Yesterday I was short NQ from the high 5 minute bar of the day. It got under way quite nicely and I had reduced my risk to about 0.4R. I should say that I take a fairly mechanical approach to this, as a defence against my own weakness (for moving my stop to scratch too soon - it does little against my other weakness, that for transsexual prostitutes).
Anyway, it started coming back on a reasonable reversal signal. I umm-ed and ah-ed, but decided to close (in violation of my own rules) and netted the princely sum of about 0.1R. Remember, at this point my risk was only 0.4R. Shortly thereafter, price crashed. And crashed and crashed.
My return yesterday should have been around 4.5R, which is more than enough for an excellent month for me.
Some spots are indeed hard to change.
