A few reasons:
1. Short-term double bottom.
2. This pair hasn't reached this price level since 2015.
3. I think major longs are waiting at about 1.22 but I also think it will do a bit of bouncing first before ultimately trading down to that level.
4. Because I don't think anyone else wants to based on the ideas page.
Notes:
1. Just my humble opinion only. I know as much (or as little) as anybody else.
2. Trade with money you can only afford to lose.
3. Risk management is absolutely everything when trading forex.
