What is a box trade? It is playing a break from within two particularly important Support/Resistance lines. The more imporant the lines the better chance of a clean break above or below the S/R line.

Monday for instance:

On Tuesday the price makes it to 780 and is flirting with a break:

My strike price is long 780.9 and short 739.8. My concern here is that my long, which we are very close to, may be executed in out of hours trading. Out of hours price doesn’t seem to show the same respect for S/R that it does during market open hours.

We will see what happens today.
