Possible short? Im open for all advice and critisism

FX_IDC:GBPAUD   British Pound / Australian Dollar
On the daily chart it is shown to be a downtrend.
As I enter the 4H, it shows its respecting the 20 ema .

SL is above an area of recent resistance.
TP is in the golden area of support.

if I was to enter a short. would I wait till it gets near to the 20 ema?
