A counter-trend move, is it a good idea

If you have been following me for sometime, you would know that I've my bias in looking to long the US Dollar.

At this moment, there isn't such opportunity, but multiple shorting opportunity presents itself, in this moment, the bearish crab pattern, retest on the 4-hourly chart.

I will take the trade once the market has show the confirmation and will treat it as a counter-trend trade.
