iBands

Calculates the Bollinger Bands® indicator and returns its value.

double  iBands(
   string       symbol,           // symbol
   int          timeframe,        // timeframe
   int          period,           // averaging period
   double       deviation,        // standard deviations
   int          bands_shift,      // bands shift
   int          applied_price,    // applied price
   int          mode,             // line index
   int          shift             // shift
   );

Parameters

symbol

[in] Symbol name on the data of which the indicator will be calculated. NULL means the current symbol.

timeframe

[in] Timeframe. It can be any of ENUM_TIMEFRAMES enumeration values. 0 means the current chart timeframe.

period

deviation

[in] Number of standard deviations from the main line.

bands_shift

[in] The indicator shift relative to the chart.

applied_price

[in] Applied price. It can be any of ENUM_APPLIED_PRICE enumeration values.

mode

[in] Indicator line index. It can be any of the Indicators line identifiers enumeration value (0 - MODE_MAIN, 1 - MODE_UPPER, 2 - MODE_LOWER).

shift

[in] Index of the value taken from the indicator buffer (shift relative to the current bar the given amount of periods ago).

Returned value

Numerical value of the Bollinger Bands® indicator.

Example:

if(iBands(NULL,0,20,2,0,PRICE_LOW,MODE_LOWER,0)>Low[0]) return(0);
