Thinkscripts to pull call and option volume and plot them as an overlayed histogram. Initial script by JeanTann3n. Refactored and optimized by Wahakalaka.
Make sure to set same-day date alpha transparency in the Study options. CreateColor does not allow alpha to be specified.
- There is a lot of data being processed, so we recommend using a longer aggregation period or a shorter time interval if you're seeing performance issues.
- Currently strikes are pulled in dollar increments.
- Something like SPSX is going to be difficult because of the number of strikes.
- It might take a while to load everything, be patient.
- Futures (/ES, etc) aren't working currently due to the way option symbols are matched. (Todo hardcode a fix for /ES)
- Strike ranges and expirations need to be set manually, right now. On the plus side this allows for effective filtering to a specific delta range if you look up what the strike range is for the equivalent delta range.
- The volume data is not raw order data, so specific sale prices, order sizes, etc. cannot be inferred.
