MACD colored with change color prediction
Nikolay.Gekht · Wed Mar 30, 2011 4:43 pm
The indicator is a port of MACD_Colored_v102.mq4 by Herb Spirit (http://www.forexfactory.com/showthread.php?t=20349)
This is the simple MACD where histogram := FastEMA - SlowEMA and signal := SMA(histogram)
The higher/lower than previous bars are colored. The default parameters are optimized for 4-hour strategy.
The highlight of the indicator is that, being applied on the live chart, shows the distance in pips between the current price and the price at which the current histogram bar will be equal to the previous (i.e. will change it’s color). the positive value means that the price must go upward and the negative value means that the price must go downward.

p.s. The indicator may be interesting for the developers. Please see this post about how properly port such indicators to Lua: viewtopic.php?f=28&t=3790

Is it possible to have this indicator corrected or have the MACD On Off Indicator incorporate the prediction functions. Thank You

I am currently using it but would like to see the blue bar predictor as in the other indicator but that one does not work.

When I load the Macd On / Off parallel with the Macd color with change prediction indicator, the Macd color with change prediction indicator does not line up even after I confirm the settings are the same. Please assist. Thank You.

Could you add three sets of line level options? set 1 default .00015 and -.00015 color, width, style set 2 default .0003 and -.0003 color,width, style set 3 default .00045 and -.00045 color, width, style Thanks

Your request is added to the development list.

Thanks a million for this indicator! The traditional MACD on market scope does not allow for the value of 1for the signal line. This version of MACD is used for the 4HR MACD strategy which has a very high success rate, better than most of the expensive strategies out there. I know because I’ve tried alot of them. Just google 4HR MACD strategy. It’s very popular and you’ll be glad you did. (sorry, if this comment is not in the appropriate section).

Hello Developer,
I am wondering if you can also add the signal line to this indicator.
I currently have 2 separate MACD indcators: (1) gives me the MACD movements as a colored histogram (Green/Purple) but no signal line (2) the MACD indicator with histogram colored only grey if it moves to other side of signal line (Red/Blue/Green) but the histogram logic is NOT the same as (1)
So if you can add a signal line to this indicator, that will meet my need.
Please advise when you can deliver this
Many thanks

Signal line is already available.

Hello Apprentice,
The parameters you have shown me are for the 2nd indicator which has the Signal line but the logic for the MACD coloring is based on when it crosses the signal line.
I am looking for a signal line parameter for the 1st indicator which does NOT have a signal line and the logic of the MACD coloring is based purely on the previous MACD histogram and not on anything else.
If you see the parameters for the 1st indicator (attached) there is no signal line to setup.
Can you add the signal line to the 1st indicator please
Thank you.

My apologies, after i posted my reply to your post, I realized that this is a the 3rd indicator which you are referring to that already has the signal line. Sorry for the confusion, I got what I was looking for.

The indicator was revised and updated.
