The "dynamics" you speak of are subject to change without warning.
And there is confusion over whether trades are long or short term.
To me, either you are a rocket scientist, or a fast talker. No offense. Just that without a recipe (a set of rules) it is like listening to a PhD explain Quantum Mechanics. I think that if you could tell us how fundamentals and other tangibles play into this, it would be enlightening.

Hi,
It's not gambling if one has taken the time to learn how the market works. Most successful traders would resent being called gamblers. It IS gambling when a newbie has no idea how the market works, how a system works, and throws real money on the table.
Correlation trades can be either long or short term. Long term correlation trading is better in the direction of positive swap, but that is discussed elsewhere in this thread. I prefer short term. Last August was a perfect example why. I was trading the EURUSD/GBPUSD correlation and went for a medium term trade.
Wham - the news of the hoof and mouth disease hit England and the GBPUSD dropped fast and briefly decorrelated. When things settled down a few days later the strong correlation resumed, but the two pairs then had a several hundred pip negative separation and I was stuck in that stupid trade. Read my posts about walking through the mall as an explanation of correlation and divergence.
I am neither a rocket scientist or a fast talker. The dynamic is there. To explain a bit using the EURUSD/GBPUSD pair. First, understand that there are secondary influences on this correlation.
Rule - three related pairs always work mathmatically together. If the GBPUSD rises and the USDJPY rises, the cross (GBPJPY) will rise strongly. This is straight math. Multiply the GBPUSD by the USDJPY and you will get the price of the GBPJPY.
Correlary - if the price of the cross moves dramatically (GBPJPY sell off for example) the two primary pairs GBPUSD and USDJPY must move because the math works both ways.
Basically, the tail can sometimes wag the dog. The JPY crosses have been in violent movement since last June, causing mayhem in the primary pairs, and hence their correlations. Imagine a very, very, happy Labrador Retriever wagging his tail - the whole body is in motion, bouncing all over the place.
The primary factor is not the strength of a given currency in a correlated set, but rather the
significance of that currency. For example, while the EUR was stronger a year ago than the USD, it was
the USD that was more significant as it moved relatively more strongly than the EUR or GBP in response to technical, fundamental, and sentiment data. During the second half of the year,
the relative significance of those currencies changed, which negatively affected the correlation, making it more random.
To use an illustration, imagine a very large parent holding the hands of two very small children. Those children will be pulled in the direction in which the parent travels. It is the parent who is significant. Then, imagine three small children holding hands. Nobody is significant, they have no correlated direction and are all over the sidewalk.
Rule - correlated trades always work best in pairs where the currency in common is significantly more dynamic (this does not mean stronger) than the other two currencies.
So, it is not the fundamentals, such as a GDP or payroll trend that is directly important, but how significantly that currency will behave relative to the other two currencies. A year ago the USD was far more significant than the EUR or GBP, so the EURUSD/GBPUSD pair was logical. Is the USD more significant today? No. In fact, on given days or weeks, any of these three can take the lead at this time. That is the current "dynamic."
I hope this helps.
Trade carefully,
Bill
