EA FX Strength

Hello, I'd need help to code a simple EA that enters orders based on Strength on 8 currency pairs. The EA monitors the 8 fx pairs strength in the past x hours (input of EA) and enters position on the strongest vs weakest. The EA check of which pairs is strongest and weakest is performed every x minute (input of the EA). 

The position should be based on % of Equity Balance and ATR unit of FX pair to be traded

The code of the Strength indicator should be something like below: 

v1=security('EURGBP',period) 
v2=security('EURJPY',period) 
v3=security('EURUSD',period) 
v4=security('GBPJPY',period) 
v5=security('GBPUSD',period) 
v6=security('USDJPY',period) 
v7=security('EURCAD',period) 
v8=security('EURNZD',period) 
v9=security('EURCHF',period) 
v10=security('EURAUD',period) 
v11=security('GBPCAD',period) 
v12=security('GBPNZD',period) 
v13=security('GBPAUD',period) 
v14=security('GBPCHF',period) 
v15=security('USDCAD',period) 
v16=security('NZDUSD',period) 
v17=security('USDCHF',period) 
v18=security('AUDUSD',period) 
v19=security('AUDCAD',period) 
v20=security('AUDNZD',period) 
v21=security('AUDCHF',period) 
v22=security('AUDJPY',period) 
v23=security('NZDCAD',period) 
v24=security('NZDCHF',period) 
v25=security('NZDJPY',period) 
v26=security('CADCHF',period) 
v27=security('CADJPY',period) 
v28=security('CHFJPY',period)
