How to call historical volatility from IB

[pstrusi]

Hi NT,

I was reading NT7 guide searching how to call the instrument's historical volatility from IB. I'm don't know if IB's connectivity allows this procedure. So, let's suppose that IB gives this info, that would be through this method:

protected override void OnFundamentalData(FundamentalDataEventArgs e)
{
    if (e.FundamentalDataType == FundamentalDataType.HistoricalVolatility)
         Print("HistoricalVolatility = " + e.HistoricalVolatility);
}

Questions:

- How to call this method once a day? Where to put in the code?
- I've read in IB's TWS documentation that historical volatility that is given is 30 days, so what if I need 1 year?

Thanks

Hello pstrusi,

Thanks for your post.

Getting Fundamental data information is similar to realtime market data feeds like OnMarketData, there is not an ability to get this information historically and they update as they are sent from the data provider. When the script starts, OnFundamentalData will show the values which already exists. I suggest saving these values to a variable to use them elsewhere in your script and then you can reference those values at your desired point in time.

One item to note, is that you will want to print e.DoubleValue for the value of HistoricalVolatility.

        protected override void OnFundamentalData(FundamentalDataEventArgs e)
        {
            if (e.FundamentalDataType == FundamentalDataType.HistoricalVolatility)
                 Print("HistoricalVolatility = " + e.DoubleValue);
        }

Please let me know if I can be of further assistance.

Hi Jim, thanks for addressing the questions, allow me to rephrase them in order to get a better understanding of properties:

1. Where would this method go in the code, before OnBarUpte, after OnStartUp....?

2. If I understand well, this info will be thrown by IB as soon is updated and it will feed into my code?

3. How to call ImpliedVolatility from IB ? IB's TWS gives this info but in the NT7 guide I just see these fields:

FundamentalDataType

Possible values: AverageDailyVolume Beta CalendarYearHigh CalendarYearHighDate CalendarYearLow CalendarYearLowDate CurrentYearsEarningsPerShare FiveYearsGrowthPercentage High52Weeks High52WeeksDate HistoricalVolatility Low52Weeks Low52WeeksDate NextYearsEarningsPerShare PercentHeldByInstitutions PriceEarningsRatio SharesOutstanding

Thanks

Hello pstrusi,

The code would reside in your NinjaScript's class. Neither in OnStartUp or OnBarUpdate but at the same level as those methods.

When the data provider updates these values, OnFundamentalData will iterate for any updates here.

ImpliedVolatility is not a supported Fundamental Data value, only the values listed for FundamentalDataEventArgs could be referenced with OnFundamentalData.

Please let me know if I can be of further assistance.
