Closing My Short GBP Trade At 1.22

I am closing my recommended outright short of GBP vs USD now that it has depreciated to 1.22. This is net payout of 180% given initial trade was at 1.33 with a stop above 1.37. Even though i still believe in the original target of 1.1, the upside/downside is not as convex as it was initially. I would put the trade back on if the GBP move back closer to the original level of 1.33.
