System not working !!!! help

[vittoriacacace1111]

Hi, I have created this simple system witch has the task of buying when the moving avegrae on dayli chart is above the price bid and the adx is below 30 while it has to sell when the moving average is above the bid price and the ADX is above 70; 

But I don't understand why it doesn't work , among other things the period of the moving average should be 100, but when in the platform I check the input data the period of the moving average is 12 ; 

Can you tell me where I went wrong ?
Thanks in advance !
