SPX500 short/ approaching potential re-entry

SPX has been looking solid for a short off the 1 hr/4 hr. The trend began within a channel, but there has officially been a breakthrough. It experienced some resistance around the 3380 price reversal zone. Should it break through and reach all the way to the 3438 area, there may be a complete reversal or a strong resistance @least.

I've been trading for almost 3 months now. This is my first mark-up. Feedback would be much appreciated. LMK what you think.
