Here is the ES Chart, as you can see its working.

Anyone have any ideas, to correct this EFS to work for FOREX data??

Re: Colored MACD no display?

The reason why the plots are compressed when using some forex symbols is that the values of the histogram are limited to 2 decimals in lines 177, 179, 181 and 183 using the .toFixed() method (see the link to the corresponding article in the EFS KnowledgeBase for its usage)

/*** Updated 12/1/2003 ***

*Added FunctionParameter objects for user defined inputs.
*Added drop-down lines to the MACD where the color will
match the up/down colors of the histogram up/down color
settings. When MACD is positive, drop-down lines will be
the up color and down color when the MACD is negative.
*Added options to enable/disable MACD historgram, Signal,
MACD and MACD drop-lines.
