Hi leonlee,
I think you just need to take a little time in your trades and look to see what the higher time frames are doing first before entering on the H4, as Philip has said we need to wait a little first and wait for the correct setup, I will show you how i see the GBP/CAD going at the moment.

H4 CHART
Hope you are using Demo account first…! Please dont trade live until you fully understand your actions…
Good Luck…
