Now I see where you are at. That's not what I'm about on this thread and I will not post any screen shots. But, go ahead and post the screen shots, and keep posting them if you need to show what you do.
There was intraday resistance at the earlier high at 42.20. An entry at 42.00 would have been very aggressive.
Your trade worked out. Great. Place a trendline accross the high at 9:50 and you'll see where it came back at 12:32 to test for support at the 9:50 high resistance I mentioned earlier, and it then traded up. There was big volume gain working for you in MERQ.
