Can anyone comment on Moving Averages in the forex market?
I agree with the comments above and can perhaps add one of my own ...
I've spent quite a lot of time looking at ways of filtering MA crossovers on slower-periodicity Forex charts. This isn't how I actually trade, myself - I don't use indicators for that - but it remains an interest though I'm not altogether convinced about the probability of discovering anything that's viable in the long-term.
Still, if you look at 3-hour and 4-hour Forex charts and take something simple like a 5-EMA and 20-EMA crossover (personally I would always be looking at EMA's or WMA's rather than SMA's), it certainly seems to be the case that if prices move enough to cause such a crossover AND keep moving for quite a while after the cross, there's a high probability that there'll be some more mileage in the trend. I'm not talking just about the fact that "continuation is more likely than change" (which is true, anyway), but suggesting that it _might_ theoretically be possible to define parameters which could lead to a profitable, trend-based "trading system".
This is the nature of the celebrated "Bunny-Girl WMA Cross System", discussed exhaustively elsewhere, which has certainly been traded successfully (and with shorter-periodicity charts than I've mentioned) by some people in the medium-term, though I believe that attempts to reduce it to a "simple, mechanical system" have, perhaps unsurprisingly, so far been a total failure.
It's also (together with par-sar) the nature of another system I've been looking at, which trades only very occasionally (perhaps so occasionally that some wouldn't really call it "trading") but so far with an extraordinarily high success-rate. All of which makes me think that it's still possible there's "something in it".
For myself, I'm interested in looking further at the probabilities of trend-continuation after an EMA crossover followed by a break through a point of comparatively recent resistance/support. I suspect, though, that such a "system" would turn out to have more to do with levels of support and resistance than with the MA crossovers themselves.
One thing which is fairly certain is that MA crossover signals need a _lot_ of filtering, one way or another, to become viable in the long-term.
