|sdi_ivp release 1.3 on spy|
then, as tina turner says "we never do nuthin' nice and easy," i complicated it a little. i tied the label color to the current color of the dots. maybe you want to show a midrange - there's a parameter for that. maybe you want to place the dots below the low of the chart - there's a parameter for that. maybe you don't like the choice of text for the label - there's a parameter for that. maybe you don't like the colors for high/mid/low - there's a parameter for that.
about the new default text for the label: i decided that i like this text to be "iv%r" for implied volatility percent range. this is because there is precedent for this nomenclature in the technical indicator biz e.g. williams %r, and i don't like the appellation of rank, which i think implies something completely different. a rank is the ordinal value of an item in a list e.g. class rank. i think that calling this indication a rank will eventually lead to ambiguity when people begin comparing implied volatilities between companies e.g. in the same industry. but, hey, i'm just a small dog investor so call it what you want ... there's a parameter for that.
as always i maintain the new releases for a thinkscript on the original blog post which you can get here.
