Hellow Yellow,
I can only express my personal opinion, and that is with the benefit of hindsight

I don't think that this was a particularly bad trade set up, although I doubt that i would have taken it (hindsight is very useful

)
Take a look at the chart that you have posted, the price had shown a lot of reaction to your support line. Certainly it has been acting as a very strong support and so it is quite reasonable to expect it to bounce up from it again.
I have to ask you though, did you note the 2 recent highs that effectively formed a double top? Did you see the relationship of these 2 highs with the MACD? The second closing high was slightly higher than the first, but the MACD was much lower. This divergence with the MACD should have suggested that you look for a shorting opportunity and a break of the well established support line.
Also, if you take a look at the H4 chart at the time of your trade, there were a lot of indecisive candles previous to your entry.
Good luck
Keith
