Sorry if this has been repeated but I've looked back a few pages to no luck. I'll make this quick. Would it be possible to get Implied Volume and Historical Volume indicators or is that out of the quuestion?

Thanks! 

It is not possible to add Implied Volatility to your chart, but it is possible to plot Historical Volatility.

Historical Volatility (HV)

The formulas can be quite a bit shorter in TC2000 v17 than the formulas explored in the above topic for previous versions of TC2000.

Historical Volatility

1600 * ABS((SUM(LOG(C / C1) ^ 2, x) - LOG(C / Cx) ^ 2 / x) / x) ^ .5

Where x is the period of the Historical Volatility indicator.

HV Ratio

SQR(ABS((SUM(LOG(C / C1) ^ 2, n) - LOG(C / Cn) ^ 2 / n) / n)) / SQR(ABS((SUM(LOG(C / C1) ^ 2, d) - LOG(C / Cd) ^ 2 / d) / d))

Where n is the first period specified which is used for the historical volatility in the numerator.

Where d is the second period specified which is used for the historical volatility in the denominator.

So a 100 period Historical Volatility can be written as follows.

1600 * ABS((SUM(LOG(C / C1) ^ 2, 100) - LOG(C / C100) ^ 2 / 100) / 100) ^ .5

And an HV Ratio 6/100 can be written as follows.

SQR(ABS((SUM(LOG(C / C1) ^ 2, 6) - LOG(C / C6) ^ 2 / 6) / 6)) / SQR(ABS((SUM(LOG(C / C1) ^ 2, 100) - LOG(C / C100) ^ 2 / 100) / 100))
