Macd Advanced

[guru73]

I would like to build the indicator following:

name = SLT

SLT = It show the level of price to which the indicator MACD changes inclination.
The level of the price has also shown in the cursor window.
SLT line is drawn on the graph of the price.
If MACD study is down = SLT line is above the price.
If MACD study is up = SLT line is under the price.
MACD down = MACD(0) < MACD(-1);
MACD up = MACD(0) > MACD(-1);
I use MACD with simple moving average.
I hope help me, and sorry for my bad english, thanks in advance.
