Hi I had a questions concerning gaps on nyse stocks. On Friday 13, 2003 I was trading APA in the morning around 10:00 am I got in long around the whole number say for example it was 37 I dont remember what price it was at the time. Anyway I made my out on the downside 10 cents lower or so. Anyway all the sudden the next print was 40 cents lower and the bid went from say example 37.00 to 36.60 This is ridiculous Is there any early indication or way I could tell if the stock will gap or something??? there was no way I could of got out its not like I held a 40 cents loss this was the next print?? any ideas how to avoid these types of situtaions? is there any way you can tell if this will happen?
