MACD based Indicator

Hi guys,

I want to create some easy (I hope) indicator, that paints colored candles based on MACD indicator.

I've uploaded two MACD indicators on the chart for easier visualization, both have same MACD settings.
- First one is typical bottom MACD.
- Second one is in the form of arrows on the chart.

Ok how it should work:
When a MACD typical cross signal occurs, indicator should check if MACD bars are above or below 0 value.
What I mean of MACD 'above/below' is the white bars (not red MA). (Please check pic 1.)

Now:
- when up MACD signal occurs and MACD bars are above the '0' candles should have blue color.
- when up MACD signal occurs and MACD bars are below the '0' candles should have white color.
- when down MACD signal occurs and MACD bars are below the '0' candles should have red color.
- when down MACD signal occurs and MACD bars are above the '0' candles should have white color.

Please check pic 2.
1. MACD up signal, MACD bars are above the '0' = blue candles
2. MACD down signal, MACD bars are above the '0' = white candles
3. MACD up signal, MACD bars are below the '0' = still white candles
4. MACD down signal, MACD bars are below the '0' = red candles

Indicator should have adjustable MACD settings, also adjustable candle colors. It should have candles back number, that has color. (for example last 100 candles).
I would like also to implement MT4 sound alert, e-mail and push notification, when candles change color.

Best regards

M.
