SetIndexStyle sample and settings descriptions
void SetIndexStyle( int index, int type, int style=EMPTY, int width=EMPTY, color clr=CLR_NONE)
Sets the new type, style, width and color for a given indicator line.
Parameters:
index - Line index. Must lie between 0 and 7.
type - Shape style. Can be one of Drawing shape styles listed.
style - Drawing style. It is used for one-pixel thick lines. It can be one of the Drawing shape styles
listed. EMPTY value means that the style will not be changed.
width - Line width. Valid values are: 1,2,3,4,5. EMPTY value means that width will not be changed.
clr - Line color. Absence of this parameter means that the color will not be changed.

iMA example and settings descriptions
double iMA( string symbol, int timeframe, int period, int ma_shift, int ma_method, int applied_price, int shift)
Calculates the Moving average indicator and returns its value.
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.
period - Averaging period for calculation.
ma_shift - MA shift. Indicators line offset relate to the chart by timeframe.
ma_method - MA method. It can be any of the Moving Average method enumeration value.
applied_price - Applied price. It can be any of Applied price enumeration values.
shift - Index of the value taken from the indicator buffer (shift relative to the current bar the given
amount of periods ago).
