CRASH? S&P500 price bounced down from resistance

Here is where I opened short on S&P500 cfd. If it crashes I make a lot of money. Risk to reward is somewhere from 1:25, to 1:50.
I opened just because of bounce from level, I don't even use fibonacci and trendlines were all broken somewhere and are there just for show.
What do you think?
