from my view, I 've been trying to find a way to "Hedge" my currency pairs. I got burned a couple of times, and i want to make sure that I will have a chance to reduce my losses, and give me fighting chance to know what directions the currency pair is headed. What do I mean by this? well...
for example, recently I bought gbp/jpy. at the high level.at the time, i wanted to let it sit there and ride it out, and I thought the interest rate collected will help offset the position as it goes down. I'd figure if I hold it for one year, I'd be ok. HOWEVER, the market really gone down, from 240 to 221. YIKES!!!. i got BURNED!!. I was hurting, and lost some money.

.
now, I've been researching the same currency pair, and I'd figure.. What if I "Hedged" it with a another currency pair(buy one, and sell the other pair)? I'd figure, at least for the moment, even though I THINK its going on one direction, I'd be protecting myself because I'd be selling the other pair at the same time. yes, I wont be making too much money, but at least if it gone down the other direction, I'd be giving myself a fighting chance to readjust myself, and sort of eliminate the emotional aspect of trading.
Here how I been doing this via practice account.
I would buy gbp/jpy, and I would sell eur/jpy. these two currency pairs move exactly the same way. I noticed when they move, gbp/jpy moves 1.5x faster than the eur/jpy. so what I do is I would purchase 5(mini lot) of gbp/jpy, and I would sell 8 lots eur/jpy. because of the commision of course you start out with like 60 dollar in the red., but if you leave it there, somehow, one of these pairs gotta start moving up , and the other move down. The point is...I gave myself a fighting chance to determine direction. If it gone down, that means, at the right time, I would buy back the eur/jpy to collect profit from the downturn, and when it rebounds, I can either rehedge by selling eur/jpy, or sell gbp/jpy for whatever profit I have gained from the two.
I caught myself buying one direction, and yes, holding the position. but when i do find it that I am down 100 to 200 pips, its already twoo late, leaving me vulnerable , and loss of confidence, in finding the right trade.
This strategy provides me a chance to become less emotional, but remain objective to my plan. If it gone down, I'd still be confidence to make the right decision without emotional pain.
of course its still work in progress, but i guess you can sort of compare this strategy similar to a "straddle", a term commonly used at the options market .
