I have been trying for hours, How on earth do I get the s@p 500 chart on. I typed s&p500, spx etc. How do you do it. please help me

I assume that you have price data and have set AmiBroker data folder in the program. Then

Plot( C, "", colorPaleGreen, styleBar ); //use any color and bar style

All of this is explained in HELP and the ;Users Guide.
