Trading Forex in Baskets to diversify trading risk for both, speculative trading or hedging Forex risk by 
The Forex market is a mixture of corporate activity, hedging their corporate currency risk and speculators on the other side.
Corporations, like import/export companies etc. have to calculate each time their amount of risk when they do a deal.
They have a different view compared to the speculators.
In the chart below we calculate how much percent we like to hedge long/short.
On November 25 the EUR/USD at 1.2930 turned up and changing trend.
The bars got a green color, the percent indicator came above zero and indicate to hold 30% long.
Since then, the long EUR/USD position turned to 80% as today.
Again this is not a strategy for speculators but a defensive model to hedge corporate Forex risk.
Of course this can be done with others securities as well, like Dow Jones, Oil etc.
Important is to stay with the strategy on daily basis and so adjusting positions.
It’s all about discipline!
