but to put it in simple terms, you can go long CHF/JPYQuote from oldtime:
well, CHf/JPY is already a spread, maybe spread is not the right term, I just spread it out over 5 currencies, like AUD, CAD, EUR, GBP and USD. You pay more in commisions and spreads in exchange for flexibilty. It involves a lot of scaling in (including averaging down.)
Averaging down gets a bad rap, but if one of your losers has not been stopped out and starts moving better than anything else you have on why not add to it? It would be a an entry signal if you hadn't already entered too early. (but I keep them on a short leash, and if they don't perform they get cut back)
or you could go short USD/CHF and long USD/JPY, same difference if you are keeping score in USD, but twice the expense. But later you may want to add to one side and not the other.
