    File Name: getWeeklyOHLC.efs

    Description:
    Returns the Weekly OHLC data with the use of callFunction() and may be used with any interval less than weekly.

    Formula Parameters:
    sPriceSource: No Default value. Pass “Open” /”High”/”Low”/”Close” to callFunction()

    Notes:
    Save this formula to /eSignal/Formulas/OHLC/ and use this formula through the callFunction() function from your custom formulas to get the current week’s OHLC prices.

    Code Example:
    PHP Code:
    function main() {
        var 
    vData callFunction("/OHLC/getWeeklyOHLC.efs""main""High");    
        if (
    vData == null) return;
        return 
    vData;
