Potential Short in the EUR/USD, Dollar Index Near Support

As much as I don't like TREND-LINES this one looks too good to ignore for a possibility of a reversal today OR on the 21st-22nd of March. At least short term reaction of sorts. Also the 30min chart in the EUR/USD shows 1.137-8 as potential shorting targets  
The only problem is THOSE ARE TREND LINES and are obvious. DXY level to watch 96.26-96-30

Trade closed manually:

Upon reviewing the other trading ideas in TV, everybody and their brother took short position like me @ 1.1355-1.1360 looking @ the trend-line. This gives me NO CONFIDENCE it will work as when many people look @ something, it most probably wont work. Even if EUR/USD crashes here I am out of the trade.Maybe will re-enter a bit higher or just switch to a longer time frame for an entry.
