GetRSIStudy() Advanced GET Study Functions
Creates object, which allows to get values of indicator Advanced GET Relative Strength Index in EFS scripts. The Advansed GET RSI returns three lines, the RSI and two moving averages of the RSI. The RSI is calculated by finding the percentage of positive closes (the current close is higher than the previous close) to negative closes (the current close is lower than the previous close).
Syntax
GetRSIStudy( nLength , PriceSource , nMavg1 , bExp1 , nMavg2 , bExp2 )
Parameters
| Parameter: | Description: | Default: |
| nLength | Number of periods to use for calculation of RSI.
|
n/a |
| PriceSource | String. One of the following values: "Open", "High", "Low", "Close", "HL/2", "HLC/3", "OHLC/4", "Volume".
|
n/a |
| nMavg1 | Number of periods to use for calculation of the first Moving Average.
|
n/a |
| bExp1 | If this parameter is True the first MA is calculated as exponential, if False - as simple.
|
n/a |
| nMavg2 | Number of periods to use for calculation of the second Moving Average.
|
n/a |
| bExp2 | If this parameter is True the second MA is calculated as exponential, if False - as simple.
