Algo Trader system could work with 9 pairs/18 timeframes:

EURUSD, GBPUSD, USDJPY, AUDUSD, NZDUSD, USDCAD, GOLD,  WTIOIL, DollarIndex

(H1+H4 Timeframe)

The logic of Algo Trader includes price action, pivot and trending following method.

It is very simple, but it does take me several years to find it...

It works on H4 and H1 timeframe with filters from higher timeframe.

When short term trend, medium term trend and/or  long term trend all turn green, and the price also closed above the upper bands, this should be a perfect medium term buy opportunity.

When short term trend, medium term trend and/or long term trend all turn magenta, and the price also closed below the lower bands, this should be a perfect medium term sell opportunity.
