covered in the past scenario recognition can be very profitable learned skill. The more chart patterns and their subsequent out comes given the tape environment the quicker you as a trader are able to identify and profit from the price action.
The chart to the left is of Alcoa which had M&A rumors this morning sending its shares surging higher the first hour of trading before tailing back a bit and catching off 12.87. The bid off 12.87 was my signal the buyer is still there and has size to take down. I decided to hold onto
my 11 calls i purchased around 12.80 until she broke over 13. The way she traded at 13 without busting through though not falling 5c below 13 for nearly an hour told me she is going to go high. Eventually you can see the volume at the bottom of the chart confirmed there was indeed buyers watching the 13 level as 730k shares were bought sending AA up nearly 10c very quickly.
Trades like this are simple with risk minimal because you are able to place a tight protective stop while letting your longs run it a bit more size because you are confident in the scenario.
