need help on MACD

i need to know the highest value of indicator counted, for example this is function on standard MACD.
MacdBuffer[i]=iMA(NULL,0,FastEMA,0,MODE_EMA,PRICE_CLOSE,i)-iMA(NULL,0,SlowEMA,0,MODE_EMA,PRICE_CLOSE,i);

what function I should use to write these MacdBuffer[i] highest value for last 100 bars..
sorry for my english and the question, both are not my native language.

I'm not sure if this will work on an array but give it a try. You may have to declare or define the array


int iHighest(string symbol, int timeframe, int type, int count=WHOLE_ARRAY, int start=0)Returns the shift of the maximum value over a specific number of periods depending on type.
Parameters:
symbol - Symbol the data of which should be used to calculate indicator. NULL means the current symbol.
timeframe - Timeframe. It can be any of Timeframe enumeration values. 0 means the current chart timeframe.
type - Series array identifier. It can be any of the Series array identifier enumeration values.
count - Number of periods (in direction from the start bar to the back one) on which the calculation is carried out.
start - Shift showing the bar, relative to the current bar, that the data should be taken from.

Sample:
double val; // calculating the highest value on the 20 consequtive bars in the range // from the 4th to the 23rd index inclusive on the current chart val=High[iHighest(NULL,0,MODE_HIGH,20,4)];

int highest;
highest = iHighest (NULL,0,MacdBuffer,100,0);

Again I'm sure if this is correct but its were I would start...I'd bet some of the coding gurus could tell you specifically...I'm just an amature who's taking a crack at it.

Many Thanks gspajon..

Here's how to do it manually:


I don't think the iHighest() function will work in this case.

got it, thanks M256..
