The following stronger currencies are well represented for going long: NZD(4X) followed by the USD(2X) with the CHF(2X). The weaker currencies are the EUR(4X) with the GBP(5X) followed by the CAD(3X).
A nice combination for coming week may be e.g:

Some of the pairs in the Top 10 comply for a longer term trade based on the Technical Analysis (TA) of the Daily and Weekly chart. For the coming week these seem to be: 
GBP/NZD, GBP/USD, GBP/CHF, NZD/CAD, USD/CAD and EUR/GBP. 
For more details read both of my articles where the relevant Charts and Tables are provided.

These are just a few examples and many other combinations are possible. The mentioned pair combinations can be traded at the same time according to the rules of the FxTaTrader strategy because these are all different currencies. Generally speaking, by not trading the same currency in the same direction more than once in the same Time Frame you may have better chances with lower risk. In any case it always seems better to spread risk and this can be done in many different ways.
When trading with more than 2 micro lots it is a good idea to have a diversification and depending on your preferences it may offer opportunities by going long or short on a specific currency trading it against other currencies.

Ranking and Rating list

Analysis based on TA charts for all the major currency pairs. Good luck to all. No advice, just info. Every week the Forex ranking rating list will be prepared in the weekend. All the relevant Time Frames will be analyzed and the ATR and Pip value will be set.

For analyzing the best pairs to trade looking from a longer term perspective the last 13 weeks Currency Classification can be used in support.
This was updated on 25 September 2016 and is provided here for reference purposes: 
Strong: USD, JPY, NZD. The preferred range is from 6 to 8.
Neutral: CHF, AUD. The preferred range is from 4 to 5.
Weak: EUR, GBP, CAD. The preferred range is from 1 to 3.

When comparing the 13 weeks Currency Classification with the pairs mentioned in the Ranking List above some would then become less interesting. On the other hand these pairs are at the top of the list partly also because of their volatility. It seems best to take positions for a short period then and take advantage of the high price movements.
With the FxTaTrader Strategy these pairs are not traded because these would be trades in the 4 Hour chart or in a lower Time Frame. Nevertheless they may offer good chances for the short term trader.
