Possible to add horizontal NOT moving lines?

hi All

is it possible to at on chart window horizontal NOT moving lines?
why? if jacko say: DETERMINE THE TIME FRAME THAT YOU WANT TO TRADE.

1. If the graph on the chart starts in the bottom left hand corner and ends in the top right hand corner, the market is going UP.

2. If the graph on the chart starts in the top left hand corner and ends in the bottom right hand corner, the market is going DOWN.

I think it will be more easy to see if my systems signals are below or above those lines...

these lines must be 70%, 50%, 30%

thank you in advance...
