As long as there is uncertainty I remain bearish, bolstered by a positive swap I consider it my best strategy. It might go up, and keep doing so through the article 50 and I can ride it out knowing that every night I get some extra breathing room and can cover with other pairs.
I had the same thought as you on TRY and MXN (sort of, as the trend was bullish)... started adding long positions to cover my negative short positions, now it's running sideways and swap rats on my longs started eating into my positions... time to close the long positions as time of uncertainty reared it's head. Took a 20% loss in that exercise.
Closed out my MXN in profit last night and closed the chart, I'm not comfortable trading it again any time soon.
Assuming you are right, you will make the profits now, and I will make them later in the year, if you are wrong, I will make the profits now and you will be stuck with long positions with negative swap if you hold, which would be unrecoverable in the long term.
For every loss there should be at least an equal and opposite profit.
