Question about IV & HV chart

[heizit]

Hi!

I am ploting the IV and HV of the stock on the same chart using TOS's built-in studies.

However, this chart does not look correct to me -- HV line is abobe IV line for around 20% while the indicator only shows IV is 34% and HV is 33.6%.

Does anyone know why this happens and how to fix it?

Thanks!

Plot them both in the same indicator rather than having two indicators in the same panel. Its not showing you their actual values, what its showing you is a result of the platform attempting to scale them both entirely into view.

declare lower;
plot HST = HistoricalVolatility() * 100;
plot IMP = impVolatility() * 100;
