how to pass color parameter

dear sir,

I have a problem :how to pass the parameter to user difine function :

example :

CreateObject("Test1",Green);

CreateObject("Test2",C'236,130,0')

CreateObject("Test3",32768 )

void CreateObject(string Name1,int DefineColor)

{

ObjectCreate(Name1,OBJ_LABLEL,WindowFind("Indicato r1"),0,0);

ObjectSetText(Name1,"Testing",12,"Arial Bold:,DefineColor);

1. so how to pass the Color for Green, C'235,130,0,' or 32768

2. in the User define function, what is the type of the color? can be string ? int? double or color ? I have try but failed

3. what is the type variable for color, or can be convert from interger, string into color type variable ?

4. can you show me the url for this kind of problem.

thanks for the help

Hello,

I've moved your post to this thread. Take a look at posts 20#.

Meanwhile:

double iMAOnArray( double array[], int total, int period, int ma_shift, int ma_method, int shift)Calculation of the Moving Average on data stored in a numeric array. Unlike iMA(...), the iMAOnArray function does not take data by symbol name, timeframe, the applied price. The price data must be previously prepared. The indicator is calculated from left to right. To access to the array elements as to a series array (i.e., from right to left), one has to use the ArraySetAsSeries function. Parameters:

array[] - Array with data. total - The number of items to be counted. 0 means whole array. period - Averaging period for calculation. ma_shift - MA shift ma_method - MA method. It can be any of the Moving Average method enumeration value. shift - Index of the value taken from the indicator buffer (shift relative to the current bar the given amount of periods ago). Sample:

double macurrent=iMAOnArray(ExtBuffer,0,5,0,MODE_LWMA,0);

double macurrentslow=iMAOnArray(ExtBuffer,0,10,0,MODE_LWMA,0);

double maprev=iMAOnArray(ExtBuffer,0,5,0,MODE_LWMA,1);

double maprevslow=iMAOnArray(ExtBuffer,0,10,0,MODE_LWMA,1);

//----

if(maprev=macurrentslow)

Alert("crossing up");

 

iMAOnArray

iMAOnArray is not an indicator but a function that calculates the moving average of an array!

If you search my lessons you will find the answer and more details about the iMAOnArray.
