[amibroker] Re: HELP for the AFL code of Leading indicators(by John Ehlers)

["gmorlosky" <gmorlosky@xxxxxxxxx>]

AFL is easier. Use the Formula Editor icon to check your code. The 
guide has many excellent exmaples. Try this thinking:

Price = ((H+L)/2);
alpha1 = (0.25);
alpha2 = (0.35);
Lead = (0);
NetLead= (0),
EMA= (0); - EMA is a defined term - don't use it - use EMA1 or 
something

Plot(EMA1, "EMA1", colorRed, styleLine, Null, Null, 10 );
