After a horrendous previous week playing with stock futures, just traded NF with first position 0.5x of my usual, and traded without a SL. Though saw a draw-down of 25 points (50 points move), but all the bullish signals were not firing, so kept on to the loss (mental SL of 50 points, which meant a 100 point rally), and finally paid off after adding on to positions once market was in my favor..
So,
a serious (but expensive) lesson for me....no matter how tempting the set-up looks, always enter less than your usual lots because it helps in keeping very wide SLs, unless all the signals (not just PA) tell you that you are wrong.
