Tomorrow - One more monster day!

Tomorrow - Again Earnings time! NYX, VCLK, IMMR are reporting earnings.

1) I had invested heavily in NYX
Share 300 ( Bought at 73, 74.2, 77.8). Nyx is currently trading at 47.75.
Loss - 8100.
I have also bought calls recently hoping that nyx will go up after earnings(well, thats a big hope, isn't it? - nyx shareholders will know the feeling ;) as nyx seems to down on any news).
Invested $1300 in calls. Also, invest $100 in puts.

2) I had bought vclk(valuclick) 200 shares at 21.5. Its currently trading at 11.82. So I have approximately $2000 loss.

3) I had bought IMMR 150 shares at 11.1 . Its currently trading at 7.04. Loss - $620

Why I never had stop losses is a million dollar question. Its really expensive to learn simple things hard way!
